Skills Needed for Success

April 28, 2017

Scott Adams listed skills that he thinks every adult should gain a working knowledge in his book “How to Fail At Almost Everything and Still Win Big”  He writes that mastery isn’t necessary and that luck has a good chance of finding you if you become merely good in most of these areas.

Public speaking is a skill the need for which should be obvious.  Adams himself took a Dale Carnegie course on public speaking which he found quite useful.  Today he can make $100,000 for a single speaking engagement.

Business writing is another needed skill.  The emphasis here is not on business, but rather that good business writing is both concise and informative.  It provides a good model for effective writing in general.

Accounting is essential not only for businesses, but also for managing one’s household.  An understanding is also necessary for evaluating stocks.

Adams writes that in today’s world we’re all designers, whether we like it or not.  PowerPoint presentations, Web sites, or flyer’s for your child’s school events.  Furnishing you home, buying clothes to look nice to others, and so on are needed.  Design once was the exclusive domain of artists and other experts, but now we’re all expected to have a working understanding of design.

Adams notes that few people are skilled conversationalists.  Most people just talk, which is not the same thing as conversation.  The difference is that skilled conservationalists know techniques that are surprisingly non obvious to a lot of people.  Adams goes into some detail about effective conversations, and he also notes that it is a learnable skill.

Overcoming shyness is important to overcome for obvious reasons. He says that we can overcome shyness with a little practice.  It is worth the effort or one can find oneself socially drowning at every gathering or public talk. He provides examples regarding how to overcome shyness.  He writes that the single best tip for avoiding shyness is  to harness the power of acting interested in other people.

Learning a second language can qualify one for a large range of jobs and opportunities compared to monolingual peers.

He notes that the old cliche is that business gets done on the golf course.  As Adams enjoys golf, both business and enjoyment can be done at the same time.  However, HM likes to watch golf, but when he sees the difficulties and problems the best golfers in the world have, he has difficulty understanding how it can be enjoyed.  HM is in agreement with Mark Twain who said that “golf is a good walk spoiled.”

Proper grammar is important.  He provides examples of common grammar gaffes that can cause others to lower their opinions of you.

Today one also needs to have at least a working knowledge of technology at the hobby level.

He recommends having proper voice techniques noting that it’s helpful to have different vocal strategies for different situations.

Adams goes into considerable detail on each of these topics.

Two topics on his list, persuasion and psychology, will each have a post devoted to them.

Managing Your Attitude

April 27, 2017

“Managing Your Attitude” is the title of a chapter in Scott Adams’ How to Fail At Almost Everything and Still Win Big.”  Adams writes, “Your attitude affects everything you do in your quest for success and happiness.  A positive attitude is an important tool.  It’s important to get it right.  The best way to manage your attitude is by understanding your basic nature as a moist robot that can be programmed for happiness if you understand the user interface.”  This is a geeky way of saying that you control your thoughts and by controlling your thoughts you are able to manage your attitude.  This point has been made in previous healthymemory blog posts.

Although Adams makes no mention of this, the best way of managing your attitude is via mindfulness and meditation, about which many posts have been written.  Here are some tips offered by Adams.  “A simple trick you might try involves increasing your ratio of happy thoughts to disturbing thoughts.  If your life doesn’t provide you with plenty of happy thoughts to draw upon, try daydreaming of wonderful things in the future. …If you imagine winning a Nobel Prize, buying your own private island, or playing in the NBA, don’t worry that those things are unlikely. Putting yourself in that imagination-fueled frame of mind will pep you up.  Imagination is the interface to your attitude.  You can literally imagine yourself to higher levels of energy.”

However, if you are in a truly bad mood, exercise, nutrition, sleep, and time are helpful.  Once you return to you baseline level of happiness, you’ll be in a better position to get the benefits of daydreaming.

Adams also writes, “A powerful variation on the daydreaming method involves working on projects that have a real chance of changing the world, helping humanity.  Adams tries to have one or more change-the-world projects going at all times.

Adams also correctly notes that smiling makes us feel better even if the smile is fake.  When you’re in a bad mood the physical act of forcing a smile may trigger the feel-good-chemistry in our brains that is associated with happiness.

This smiling-makes-you-happy phenomenon is part of a larger and highly useful phenomenon of faking it until you make it.  He says that two-way causation can be found in a wide variety of human activities.  He’s discovered that acting confident makes you feel more confident.  Feeling energetic makes us want to  play a sport, but playing a sport will also make us feel energetic.

Adams notes the there is a bonus to smiling, “as it makes us more attractive to others.  When we’re more attractive, people respond with more respect and consideration, more smiles, and sometime even lust.  That’s exactly the sort of thing that can cheer us up.”

Goals Versus Systems

April 26, 2017

Scott Adams wrote the following as the first teaser for reading “How to Fail At Almost Everything and Still Win Big”, “Goals are for losers.”  He later concludes, “My worldview is that all success is luck if you track it back to the source. “  By this he means that no matter how good the product or idea is, there were a variety of conditions that resulted in the success of that product or idea.  Absent those conditions, the product or idea would have remained unknown.

So chance plays a large role in success.  This is why he writes “Goals are for losers.” If you meet your goal, fine.  But meeting your goal does not guarantee your success.  And even if you do meet your goal, what’s next?  And if you fail to meet your goal?  What then?

Adams argues for systems rather than goals.  By systems he means those skills and activities that you enjoy.  Different skills can be blended into skill sets.  One works systematically at building these skill sets.  His book explains how he does this, and provides general advice as to how it can be done.

There were many healthy memory blog posts on Angela Duckworth’s book “GRIT.”  Her advice is to find your passion and pursue it.  There were posts written to try to modulate this advice.  Unmodulated passion, not matter how intense, can lead to misery and failure.

These systems, of which Adams writes, can be called passions, although Adams does not do so.  But absent success, they are enjoyable and fulfilling in themselves.  Moreover, continuing to develop and enhance skill sets increases the probability of success.  With perseverance that probability becomes fairly high.

There is a chapter titled “Managing Your Odds for Success.”  It contains the following success formula:  Every skill you acquire doubles your odds of success.  He further explains that this does not say anything about the level of proficiency you need to achieve for each skill.  Nothing is implied about excellence or being world class.  The notion is that you can raise your market value by being merely good, not extraordinary, at more than one skill.

An example he provides if you are a good, but not great, public speaker, and you know your way around a Powerpoint presentation, you might have a reasonable chance of running your organization, or unit with an organization.  Adams puts this success formula into its simplest form:    Good + Good > Excellent.

Adams also notes that sometimes an entirely inaccurate formula provides a handy way to move in the right direction if it offers the benefit of simplicity.   He provides this example.  When writing a resume, a handy trick is to ask yourself if there are any words in your your first draft you won’t be willing to remove for one hundred dollars each.  Here’s this simple formula  Each Unnecessary Word = $100.

Adams continues, “when you apply the formula to your resume, you’ll surprise yourself by how well the formula helps you prune your writing to its most essential form.  It doesn’t matter that the hundred-dollar figure is arbitrary and the some words you remove are more valuable than others.  What matters is that the formula steers your behavior in the right direction.  As is often the case, simplicity trumps accuracy.  The hundred dollars in this case is not only inaccurate;  it’s entirely imaginary.  And it still works.

Here’s how Scott Adams characterizes his skill set:  “I have poor art skills, mediocre business skills, good, but not great, writing talent, and an early knowledge of the Internet.  And I have a good, but not great, sense of humor.  I’m like one big mediocre soup.  None of my skills are world-class, but when my mediocre skills are combined, they become a powerful market force.

Adams concludes with The Knowledge Formula:  The More You Know, the More You Can Know.

In other words learning and knowledge build upon themselves.

How to Fail at Almost Everything and Still Win Big

April 25, 2017

The title of this post is identical to the title of a book by Scott Adams.  The subtitle is “Kind of the Story of My Life.”  Scott Adams is the creator of “Dilbert.”  HM needs to make a confession at the outset and that is that he is an enormous Scott Adams fan.  He’s been reading “Dilbert” religiously ever since he discovered the strip.  He has the collection of DVDs of the video series made for “Dilbert” and greatly laments the loss of “Dilbert”  from the air.  He has also read many of Scott Adams’ books.

Scott Adams is not only humorous and highly creative, there is an element of truth in what he does.  He created “Dilbert” while he was working at Pacific Bell and continued to work there for several years after he had become a commercial success.  The most common comment he hears is,”You must have worked at my company.”  This comment comes from people working in both government and private industry.  So there is a core of truth at the bottom of his humor.

Should you already be a fan of Scott Adams you would certainly enjoy this book and find it interesting.  However, even if you are not a fan of Scott’s, this book is still recommended as it provides solid advice on how to succeed (eventually) and how to live a meaningful and enjoyable life.

Adams documents his many failures on his way to success.  One of his failures was a Meditation Guide the he wrote with a friend.  Adams had meditated for years and found a lot of benefits in meditation.  However, only three copies of this book were sold.  He writes that he learned about local advertising, marketing, and product development from the experience.  Unfortunately, it appears that he overgeneralized this failure to meditation itself.  Meditation does not appear in this book, although there are many areas for which it is highly relevant.

“How to Fail at Almost Everything and Still Win Big” warrants many posts that shall immediately follow.

Can Democracy Survive the Internet?

April 24, 2017

The title of this post is part of the title of a column by Dan Balz in the 23 April 2017 issue of the Washington Post.  The complete title of the column is “A scholar asks, ‘Can democracy survive the internet?’  The scholar in question is Nathaniel Persily a law professor at Stanford University.  He has written an article in a forthcoming issue of the Journal of Democracy with the same title as this post.

Before proceeding, let HM remind you that the original purpose of the internet was to increase communication among scientists and engineers.  Tim Berners-Lee created and gave the technology that gave birth to the World Wide Web.  He gave it to the world for free to fulfill its true potential as a tool which serves all of the humanity. The healthy memory blog post “Tim Berners-Lee Speaks Out on Fake News” related some of the concerns he has regarding where the web is going.

Persily’s concerns go much further.  And they go way beyond Russian interference in the 2016 presidential election.  He notes that foreign attempts to interfere with what should be a sovereign enterprise are only one factor to be examined.  Persily argues that the 2016 campaign broke down previously established rules and distinctions “between insiders and outsiders, earned media and advertising, media and non-media, legacy media and new media, news and entertainment and even foreign and domestic sources of campaign communication.”  One of the primary reasons Trump won was that Trump realized the potential rewards of exploiting what the internet offered, and conducted his campaign through new, unconventional means.

Persily writes that Trump realized, “That it was more important to swamp the communication environment than it was to advocate for a particular belief or fight for the truth of a particular story.”  Persily notes that the Internet reacted to the Trump campaign, “like an ecosystem welcoming a new and foreign species.  His candidacy triggered new strategies and promoted established Internet forces.  Some of these (such as the ‘alt-right’ ) were moved by ideological affinity, while others sought to profit financially or further a geopolitical agenda.  Those who worry about the implications of the 2016 campaign are left to wonder whether it illustrates the vulnerabilities of democracy in the Internet age, especially when it comes to the integrity of the information voters access as they choose between candidates.”

Persily quotes a study by a group of scholars that said, “Retweets of Trump’s posts are a significant predictor of concurrent news coverage…which may imply that he unleashes ‘tweetstorms’ when his coverage is low.”

Persily also writes about the 2016 campaign, “the prevalence of bots in spreading propaganda  and fake news appears to have reached new heights.  One study found that between 16 September and 21 October 2016, bots produced about a fifth of all tweets related to the upcoming election.  Across all three presidential debates, pro-Trump twitter bots generated about four times as many tweets as pro-Clinton bots.  During the final debate in particular, that figure rose to seven times as many.”

Clearly, Persily raises an extremely provocative, disturbing, and important question.

What’s Next for The March for Science?

And remember that science is essential for a healthy memory!

Science Should Inform Democracy

April 23, 2017

The immediately preceding post, “Can Science Survive in a Democracy?”, focused primarily on the funding of science.  An equally, if not more, important issue is the use of science by a democracy.  Environmental and health issues are in the spotlight, but there is a wide variety of issues that can be usefully informed by science.  The failure to consider scientific evidence can have seriously adverse consequences.

One of the best examples of this failure is the size of the prison population in the United States.  The United States has 5% of the world’s population and 25% of its prisoners.  Remember that totalitarian governments imprison political dissidents, but the United States manages to surpass even these totalitarian countries on this grim statistic.  Moreover, this high rate of imprisonment did not address the problems they were supposed to solve.

The problems that were supposedly addressed were crime and drug abuse.  The public thought the best way to address these problems was by getting tough.  Politicians picked up this public sentiment and passed laws that were excessively severe for crime and proscribed drugs.  “Getting tough” might seem like a reasonable approach.  But it is a gut response, an emotional response that involves only System 1 processing according to Kahneman.  If thought processes had been engaged, System 2 processing in Kahneman’s terminology, the question would have been asked, does science have anything that would inform us as to what would be a reasonable policy?  If this question had been raised, the clear answer would have been that “getting tough” would be counterproductive, and it certainly was.

There are very few scientists or engineers, sometimes none, in Congress.  And few normal citizens read articles relevant to science.  As a consequence, they are unaware of their personal ignorance.  So what can be done to correct this widespread ignorance?

In the schools, science is taught primarily as an academic subject, and the subjects covered are typically biology, chemistry, and physics.  This is fine, but the relevance and applications of these sciences need to be taught.  The social sciences and statistics also need to be taught.  Every citizen needs to understand inferential statistics at some level to be a responsible citizen and to make reasonable decisions about personal health.  Unless college is going to be pursued, citizens can get by without understanding geometry or trigonometry.

It is essential that all students receive this education before graduating from high school, and not just students with plans for college.

Public television and a few dedicated cable channels have good programs on these topics, but they need to be increased, and they need to be presented on the major networks.

If done satisfactorily, constituents should inform their representatives as to the importance of these topics.  Then science would not only survive, but would prosper in this democracy.  And public policies would be informed by the best available scientific evidence.

Can Science Survive in a Democracy?

April 22, 2017

This post is motivated by an article in the Comments section of the 22 April 2017 edition of the New Scientist by Dave Levit titled “Marchers, raise your banners for the tortoise pace of progress.”  The referenced March is the March for Science taking place today April 22.  His article begins, “The March for Science reflects the growing gap between slow, steady, vital scientific gains and quick-fire opportunist US politics.  A week is a long time in politics.  Science, however, is in it for the long haul.  Whether studying rising sea levels or isolating proteins in fruit fly nerve cells so that many years down the line we might have a new drug for Parkinson’s, science does not fit with the day-to-day fixed-term imperatives of government.

Politicians back fracking ventures that quickly create jobs, but talk down the risks of long-term pollution.  They take credit for the progress made in renewable energy, ignoring the decades of work underlying this progress.  Levit continues “The slow march of scientific progress does not match well with politics even on a good day.  “And today is not a good day.”

The science community has been shocked by the preliminary budget outlines from Donald Trump.  From the National Institutes of Health (NIH) to NASA’s earth science mission, science would get a buzz cut.  This makes perfect sense for Donald Trump.  Levit writes, “the impulsivity and lack of long-term thinking that places science at odds with politics seems less a feature and more a tenet of Trump’s view.   Why fund the NIH properly, helping to produce the medical advances of 2030, when he can’t see past his next tweet? If politics couldn’t handle science’s tortoise pace years ago, it should be no surprise to see this disdain reach a new peak in a faster moving age.”

This March is one day aimed at making people understand how unimportant one day actually is.  March participants are simply trying to drum up greater appreciation for evidence, scientific rigor, methodology, and expertise.  The March of Science is one of slow, steady, incremental progress.

Trump’s proposed cuts would have an immediate effect—less government spending.  But their long-term outcomes, such as delayed development of life saving drugs or preventing seas from rising to swallow Miami, apparently have little effect for many elected officials.

Levit notes that there is a chance cuts will accelerate the pace of impacts until it becomes impossible to ignore them, even though some of the damage would be irreversible.

It remains to be seen whether the March can wake us up before that happens.

Let us hope that it does wake up the congress.

We Dream Much More Than we Know

April 21, 2017

This is the conclusion from a News Piece written  by Chelsea Whyte in the 15 April 2017 issue of the New Scientist.  A new way to detect dreaming has confirmed that it doesn’t only occur during rapid eye movement (REM) sleep, and has shown why we don’t often remember our dreams.

Tore Nielsen at the University of Montreal says, “There is  much more dreaming going on than we remember.  It’s hour and hours of mental experience, and we remember a few minutes.  Low-frequency  brainwaves are detectable across the brain.  Francesca Siclari and her colleagues at the University of Wisconsin-Madison have discovered that a decrease in these waves in an area at the back of the brain is a sign that  someone is dreaming.  She says, “This zone was a little bit more awake, showing high frequency  brainwaves more common during wakefulness.  This one region seems to be all that’s necessary for dreaming.”

Siclari and her team used EEG caps to map the brain activity of 32 people while they slept.  They woke the sleeper when they showed various patterns of brainwave activity, and asked them if they had been dreaming.  Some participants reported having dreams with a narrative structure, while others were more impressionistic.  One had a dream about reporting a dream

There was such a strong correlation between dreaming and fewer low-frequency  waves in the “Hot zone” that they could successfully predict whether a person was dreaming 91% of the time.

The team found that dreams during REM sleep were linked to a rise in high-frequency brainwaves in areas the are active in waking hours.  The activity matched the brain areas that would have been active if the dreamers had been living our their dreams in real life.  The team found that the participants dreamed during 71% of their non-REM sleep in addition to 95% of their REM sleep.

Many dreams are forgotten.  Sometimes participants had a foggy idea that they had been dreaming, but couldn’t remember  what about.  In a further experiment the team found that being able to later remember a dream was linked to higher activity in the prefrontal cortex, which is associated with memory, while dreaming.  Siclari says, “The region for remembering the dream was different from the region having a dream.

So dreaming is very important for our brains.  The previous posts on willpower have shown the importance of having adequate sleep for effective mental functioning.  It seems like both education and employment typically employ schedules that hinder sufficient sleep.  This issue needs serious public attention.

Willpower Wrap Up

April 20, 2017

This is the final post on the book “Willpower:  Rediscovering the Greatest Human Strength” by Roy Baumeister and John Tierney.  The title says the greatest human strength, but it could be called the greatest human weakness as most of us not only fail to adequately foster willpower, but we also fail to make use of its potential. Perhaps a more appropriate title would have been “Willpower:  Discovering the Greatest Human Potential.”

The book also discusses how Eric Clapton and Mary Karr finally managed to stop drinking.  The exploits of David Blaine, who is perhaps the most famous current exploiter of willpower are described along with his methods for accomplishing them.  However, Henry Morton Stanley makes Blaine look like a wuss when it comes to willpower.  Stanley became famous by finding a Scottish Missionary in the deepest parts of Africa and saying, “Dr. Livingstone, I presume.”  Stanley made many trips into the wilds of Africa and encountered conditions that severely challenged his willpower.  But he never broke.  He said, “Self-control is more indispensable than gunpowder.”

HM’s only complaint with the book is that it does not discuss the relevance of meditation and mindfulness.  HM finds meditation to be a good technique for restoring willpower.  And mindfulness keeps the objectives of willpower in the mind and assists in monitoring progress.  Fortunately, readers of the healthy memory blog have many posts on both meditation and mindfulness.

Additional Willpower Strategies

April 19, 2017

This post is based largely on the book “Willpower:  Rediscovering the Greatest Human Strength” by Roy Baumeister and John Tierney.  The power of positive procrastination is another source of willpower.  The “I’ll have it later” trick is an example of positive procrastination.  At least you’re delaying the temptation.  And you might eventually forget about the temptation completely.

Another strategy is the nothing alternative courtesy of Raymond Chandler.  Chandler’s system for writing detective stories was to set aside at least four hours a day for his job, writing.  He did this methodically every day.  In the morning he would wait for inspiration.  When it came, he wrote.  If it didn’t come he would do nothing the entire four hours.  The authors write that the nothing alternative is a marvelously simple tool against procrastination for just about any kind of task.  You just might become bored doing nothing and start doing the desired task.  They key is not to do something else unless you strategically arrange the task as Robert Benchley did (see the first blog in this series, “Willpower:  Discovering the Greatest Human Strength).

The authors call the nothing alternative an offensive strategy.  Offensive strategies for not spending money would be to never carry more cash than you intend to spend, and to never carry a credit card unless it was for a predetermined purchase.  Precommitment is the ultimate offensive weapon.  Buy junk food in small packages or keep them out of the kitchen altogether.  Plan meals by the week, rather than on the spur of the moment.  Set up automatic payroll deductions, IRAs, and 401k plans.

Keeping track is another strategy .  Monitoring is crucial for any kind of plan you make—and it can even work if you don’t have a plan at all.  Weighing yourself every day or keeping a food diary can help you lose weight, just as tracking your purchases can help you spend less.  You can use technology to assist you in keeping track.

An especially important strategy is to reward often.  When you set a goal, set a reward for reaching it.  The authors write that we should steadily award ourselves for successes along the way.  Look for ways to reward yourself along the way to success prior to the big reward when the goal is reached.

Willpower Strategies

April 18, 2017

This post is based largely on the book “Willpower:  Rediscovering the Greatest Strength” by Roy Baumeister and John Tierney.  Willpower is constrained by  the availability of energy sources.  One of these is glucose, which is burned up in activities.  The other is mental energy.   Exerting willpower deletes this source, irrespective of the reason for needing willpower.  Consequently strategies are required for utilizing this resource to best advantage.  One strategy is to pick our battles.  Although we can’t control or predict the stresses that come into our lives, we can use the calm periods or peaceful moments to plan an offense such as starting an exercise program, learning a new skill, quitting smoking, reducing drinking, making one or two lasting changes to a diet.  These are all best done during times of relatively low demand, when we can allocate much of our will power to the task.  And we would want to address this tasks individually, one at a time.  Aiming for huge and quick transformations will backfire if they seem impossible.  So only address the possible.

The authors counsel us when budgeting our time, not to give drudgery more than its necessary share.  They tell us to remember Parkinson’s Law:  Work expands to fill the time available for its completion.  We need to set firm time limits for tedious tasks.  If it is a large task it might need to be addressed on different dates.  Only try to do what is realistic.

To-do-lists are good for organizing time and for making sure certain tasks are completed by a certain time.  The authors realize that some readers might not feel like drawing one up because this sounds dreary and off-putting.  So they suggest of thinking of it as a to-don’t list.  This is a list of things that we don’t have to worry about once we write them down.  Making a specific plan mollifies our unconscious minds.  We need to plan the specific next step to take; what to do, whom to contact, how to do it (in person? by phone? by e-mail?)If we can also plan specifically when and where to do it, so much the better, but that’s not essential.  Our unconscious mind can relax as long as we’ve decided what to do and put it on the list.

Whenever we set a goal, we need to be aware of the planning fallacy.  This affects everyone from young students to experienced executives (who continue to fall prey to this fallacy).  This fallacy has been extensively documented and replicated.  An example provided in the book is one by psychologist Roger Bueller and his colleagues.  They asked collegeseniors working on their honors theses to predict when they would probably finish, along with best-case and worst-case scenarios.  On average, the students predicted it would take thirty-four days to finish, but in fact it took them fifty-six days.  Not even half the students finished by they worst-case predicted date.

The authors note that self-control will be most effective if we take basic care of our bodies, starting with diet and sleep.   We need to get enough healthy food on a regular basis so that our mind has adequate energy.  And it is good to begin the day with a healthy breakfast.  The authors write that sleep is probably even more important than food:  The more researchers study sleep deprivation the more nasty effects they keep discovering.  Coffee in the morning is not an adequate substitute for sleeping until our bodies wake up on their own because it has gotten enough rest.  They write,”The old advice that  things will seem better in the morning has nothing to do with daylight, and everything to do with depletion.  A rested will is a stronger will.”

It seems that most schedules for school and work are oblivious of the importance of adequate sleep and breakfast.  This forces people to shortchange themselves on sleep and breakfast.  In turn, these shortages result in inferior performance in both school and work.  Seriously attention needs to be paid to this problem.

Smoking and Alcoholism

April 17, 2017

This post is based largely on the book “Willpower:  Rediscovering the Greatest Human Strength” by Roy Baumeister and John Tierney.  Just like dieting, quitting smoking requires your maximum willpower.  So it should be the lone habit you’re trying to rid yourself of.  One research program found that a written contract committing to temporarily stop smoking was nearly 40% more likely than a control group to be nicotine free after a year.  Given an incentive to temporarily restrain their smoking, they were more likely to make a lasting change in their lives.  What began as a recommitment turned into something permanent and more valuable:  a habit.

If you can’t bring your self to quit smoking, try cutting down to two or three cigarettes per day.  This should have health benefits plus it puts you closer to quitting smoking altogether.

Smoking cigarettes had long been regarded as a personal physical compulsion due to overwhelming  impulses in the smoker’s brain and body.  That belief was challenged  in 2008 by an article in the “New England Journal of Medicine” by Nicholas Christakis and James Fowler found that quitting smoking seems to spread through social networks.  They fond that kicking the habit seemed to be contagious.  If a member of a married couple quit smoking, the odds of the other spouse quitting increased dramatically.  The odds also increased if a brother, sister or friend quit.  Even coworkers had a substantial effect as long as the people worked together in a fairly small firm.  Generally speaking, smokers who live mainly among nonsmokers tend to have high rates of quitting, indicating the power of social influence and the social support for quitting.

Religions provide large social networks that can assist in quitting smoking.  Of course, religious people are less likely to smoke in the first place, but both new converts along with committed smokers have a good social support network for quitting.  Baumeister and Tierney  also have high praise for Alcoholics Anonymous.  Although they seem to be somewhat skeptical of the method, as good scientists they cannot argue with the results of AA.  AA does not provide an automatic cure.  Rather, it assists in developing the personal discipline using willpower to overcome alcohol abuse.

Smoking and Alcoholism are serious problems and they should be dealt with individually.   Limited willpower should be focused on each separately.

The Perfect Storm of Dieting

April 16, 2017

The title of this post is identical to the title of a chapter in the book “Willpower:  Rediscovering the Greatest  Human Strength” by Roy Baumeister and John Tierney.   Some of the content will be related plus a few contributions from this blog’s author.

Baumeister and John Tierney write, “If you’re serious about controlling your weight, you need the discipline to follow these three rules:

Never go on a diet.
Never vow to give up chocolate or any other food.
Whether you’re judging yourself or judging others, never equate being overweight with having weak willpower.

The reason for these rules can be attributed to “The Dieter’s Catch-22.”
In order not to eat, a dieter needs willpower.
In order to have willpower, a dieter needs to eat.

Oprah Winfree, along with the experience of others, and perhaps even your personal experience should be proof that diets do not work in the long term.  Although there may be short term effects, eventually we all seem to be able to find that weight that we thought we had lost.

In one experiment, using both dieters and non dieters, the participants arrived at the what researchers call a “food-deprived state.”   In other words they were hungry.  They had not eaten for several hours.  Some were given a small milkshake to take the edge off; others drank two giant milkshakes with enough calories to leave a normal person feeling stuffed.  Then both groups, along with other subjects who hadn’t even given any kind of milkshake, were asked to serve as food tasters.  Each one sat in a private cubicle with several bowls of crackers and cookies and a rating form.  As these people recorded their ratings, they could eat as many from  from each bowl as they wanted and if they finished them all, they could just tell themselves they were doing a thorough job as food testers.  Of course, their ratings didn’t matter.  The researchers were just interested inn how many cookies and crackers they ate, and how the dieters in the group compared with people who were not on a diet.

The non dieters reacted as expected.  Those who had just drunk two giant milkshakes nibbled at the crackers and quickly filled out their ratings.  Those who had drunk the small milkshake ate more crackers.  And those who were still hungry after not eating for hours went on to chomp through the better part of the cookies and crackers.

However, the dieters reacted in the opposite pattern.  The ones who had downed the giant milkshakes actually ate more cookies and crackers than the ones who’d had nothing to eat for hours.    These results have been replicated.  Finally the researchers began to see why self-control in eating can fail even amount people who are carefully regulating themselves.  The researchers gave this phenomenon the scientific term, counterregulaory eating, but this is commonly referred to as the what-the-hell effect.  So once dieters go off their diet they tend to say what-the-hell and behave like sailors on leave.

The key to successful dieting can be attributed to Mark Twain who wrote in The Adventures of Tom Sawyer, “To promise not do a thing is the surest way in the world to make a body want to go and do that very thing.”

Research has shown the effectiveness of a postponement strategy.  When offered something tempting, rather than denying it, tell yourself that you will enjoy it sometime later.  Apparently it takes less will power to postpone something rather then to deny it.  So rather than a “what the hell” effect,” there can be an “I never managed to get around to it effect.”

The chapter concludes, “So when it comes to food never say never.  When the dessert cart arrives, don’t gaze longingly at forbidden treats.  Know that you will eat them eventually, but just not tonight.”

Weight loss goals should be modest.  And all your willpower needs to be devoted to them.  Large weight losses rarely last.

The following strategies were not in the book, but HM finds them promising.
The book does mention trying to keep track of calories.  This can have the benefit of slowing down your eating.  And the slowing down itself can be quite effective.  Take time to savor each bite of food.  This can also increase your enjoyment of the meal as well as helping your lose weight.

Another tactic is to switch diets for a limited amount of time.  For example, you might become a vegetarian for a week.  This is a variant of the postponement strategy.  You postpone your regular food.  Over a period of a week you are filling up on new food.  And over this period, you might start to enjoy some foods.  You can do this periodically gradually increasing the length of time on the new diet.

Willpower 101, First Lesson, Know Your Limits

April 15, 2017

The title of this post is identical to the title of a section in he book “Willpower:  Rediscovering the Greatest Strength” by Roy Baumeister and John Tierney.  It is important to reiterate that your supply of willpower is limited, and you use this same resource for many different things.  Throughout the day you do many things that deplete your willpower of which you are likely unaware.  One activity that definitely depletes willpower is making decisions.  Practically nobody is aware of just how tiring it is to decide.  Even apparently simple decisions such as choosing what to have for dinner depletes willpower..  But deciding where to go on vacation, whom to hire, or where to look for a new job, which purchases to make and how much to spend are all decisions that deplete willpower.

Also remember that what matters is the exertion and not the outcome.  If you struggle with temptation and then give in, you have depleted your willpower regardless of the result.  You even use up willpower when you partake in indulgences that don’t appeal to you.  Forcing yourself to do something you don’t really want to do at the moment, be it chugging tequila, having sex, or smoking a cigar, depletes your willpower.

Unfortunately there is no obvious “feeling” of depletion, so you need to watch yourself for subtle, easily misinterpreted signs.  For example:  Do things seem to bother you more than they should?  Has the volume somehow been turned up on your life so that things are felt more strongly than usual?  Is it suddenly hard to make up your mind about even simple things?  Are you more than usually reluctant to make a decision to exert yourself mentally or physically?  When you notice these feelings, then review the last few hours and see if it seems likely likely that you have depleted your will power?

Although your supply of willpower is limited, it is obvious it can be replenished.  Obviously, a good night’s sleep and a good breakfast should restore your willpower.  But during the day pleasant down time should also do some replenishing.   There is another activity that HM strongly recommends, and that is meditation.  HM finds meditation most definitely to be restorative.  It is unfortunately that Baumeister and Tierney do not have meditation play a more central role.  It is mentioned that meditation rituals are a “kind of anaerobic workout for self control.”  And that “Meditation activates the same brain centers used for self-regulation.”  HM understand why they do not emphasize meditation.  They are conscientious researchers who want controlled research on the topic.  Although HM understands why they do not emphasize meditation, he criticizes their not conducting obvious research on the topic.  HM can, at least, provide his recommendation on the basis of his personal experience.  And that is that, perhaps apart from a good sound night’s sleep, meditation is the most restorative activity.  A short period, a half hour or less, of effective meditation has remarkable restorative powers.  (Enter “relaxation response” into the search block of the healthy memory blog to find relevant posts.  Additional posts can be found by entering “meditation”  or “mindfulness”)

Eat (and Sleep) Your Way to Willpower

April 14, 2017

This post is based on the book “Willpower:  Rediscovering the Greatest Strength” by Roy Baumeister and John Tierney.  Glucose depletion can turn the most charming companion into a monster.  The advice of eating a good breakfast applies all day long, particularly when you’re  physically or mentally stressed.  If you have a test, an important meeting, or a vital project, don’t take it on without glucose.  Don’t thrash out serious problems with your partner just before dinner.

Don’t skimp on calories when you’re trying to deal with more serious problems than being overweight.  If you’re trying to quit smoking, don’t try quitting while your also on a diet.  You might even consider adding some calories, because part of what seems to be a craving for a cigarette may actually be a craving for food once you’re no longer suppressing your appetite with nicotine.  When sugar tablets were given to smokers trying to quite, sometimes the extra glucose has led to higher rates of success, particularly when the sugar tablets were combined with other therapies such as the nicotine patch.

When you eat, go for the slow burn,  The body converts just about all sorts of food into glucose, but at different rates.  Foods that are converted quickly are said to have a high glycemic index.  Included here are starchy carbohydrates like white bread, potatoes, white rice, and plenty of offerings on snack racks and fast-food counters.   Eating them produces boom-and-bust cycles, leaving you short on glucose and self-control, and too often unable to resist the body’s craving for quick hits of starch and sugar from doughnuts and candy.

To maintain steady self-control, we’re  better off eating foods with a low glycemic index.  Included here are most vegetables, nuts (like peanuts and cashews), many raw fruits (like apples, blueberries, and pears), fish, meat, olive oil, and other “good” fats.

When you’re sick, save your glucose for your immune system.  Before driving to work when you’re sick consider this:  Driving a car with a bad cold has been found to be even more dangerous than driving when mildly intoxicated.  That’s because your immune system  is using so much of your glucose to fight the cold that there’s not enough left for the brain.

Sleep when your are tired.  We adults routinely shortchange ourselves on sleep with the result of less self control.  By resting we reduce the body’s demands for glucose, and we also improve its overall ability to make use of the glucose in the bloodstream.  Sleep deprivation has been shown to impair the processing of glucose, which produces immediate consequences for self-control, and, over the long term, a higher risk of diabetes.

Willpower: Rediscovering the Greatest Human Strength

April 13, 2017

The  immediately preceding post, Irresistible described the increasing addictive dangers of technology.  This and the immediately following posts will outline the solution.  That solution is willpower, and is covered in detail in a book with the title of this post  Roy Baumeister and John Tierney.   In the concluding chapter of this book they write that they’re still bullish on the future of self-control, at both the personal and social levels.  And they concede that temptations are getting more sophisticated, but so are the tools for resisting them.

Charles Darwin wrote in “The Descent of Man,” “The highest possible state in moral culture is when we recognize that we ought to control our thoughts.  Most personal problems, both personal and social, center on the failure of self-control:  compulsive spending and borrowing, impulsive violence, underachievement in school, procrastination at work, alcohol and drug abuse, unhealthy diet, lack of exercise, chronic anxiety, explosive anger.  Poor self-control correlates with practically every kind of individual trauma: losing friends, being fired, getting divorced, and ending up in prisons.  It contributed to the epidemic of risky loans and investments that devastated the financial system.  Ultimately, self-control let’s you relax because it removes stress and enables you to conserve willpower for the important challenges.

There are two important facts to understand about willpower.  There is a biological constraint on willpower.  When glucose levels are low, willpower declines.  And there is an additional constraint on willpower that is psychological.   There is a limited supply of willpower, and exercising willpower depletes this limited supply.  We use the same resource for doing different things.  This is why it is pointless to have many New Year’s Eve resolutions.  The fewer you have, the less likely any of them will be successful.  In previous healthy memory posts the recommendation was to have, at most, two resolutions.  One should be fairly easy, so at least there will be one victory, and the other should be challenging so that the success of that resolution would be grounds for cheering.  But do them in succession, say easy first, then difficult, rather than trying to do them both at the same time.

Many strategies and techniques for effectively using one’s willpower that are based on sound research are presented in the book.  One of them is positive procrastination.  For example, you might want to  have some tasty treat, but you tell yourself to procrastinate, to have it sometime later.  There is also a humorous example provided by  Robert Benchley, my favorite humorist.  In one of his essays he writes that he is often asked how he manages to accomplish so much work, given that he appears to be so dissipated.  He explained how he could summon the discipline to read a scientific article about tropical fish, build a bookshelf, arrange books on said shelf, and write an answer to a friend’s letter that had been sitting in a pile on his desk for twenty years.  All he had to do was to draw up a to-do list for the week and put these tasks above his top priority—his job of writing an article.  He wrote, “The secret of my incredible energy and efficiency in getting work done is a simple one.  The psychological principal  is this:  anyone can do any amount of work, provided that it isn’t the work he is supposed to be doing at that moment.”  I encourage readers to look up Robert Benchley on the Wikipedia.  Much of his work is still available on amazon.com.

The following is from the concluding chapter of Willpower.  “People with stronger willpower are more altruistic.  “They’re more likely to donate to charity, to do volunteer work, and to offer their own homes as shelter to someone with no place to go.  Willpower evolved because it was crucial for our ancestors to get along with the rest of the clan, and it’s still serving that purpose today.  Inner discipline still leads to outer kindness.”

You are strongly encouraged to read Willpower even though the following posts will be based on his book about this important topic, they can only scratch the surface.  Erick Clapton, Mary Karr, David Blaine, and Henry Morton Stanley. Should you not know Henry Morton Stanley, he is famous for finding a Scottish missionary in the wilds of Africa and saying, “Dr. Livingstone, I presume.”  He is a legendary figure in willpower.  He makes David Blaine look like a wuss.

Irresistible

April 12, 2017

“Irresistible” is the title of a book by Adam Alter.  Its subtitle is “The Rise of Addictive Technology and the Business of Keeping Us Hooked.”  This is an important book because it addresses an important problem, the addiction to computer games.  The World of Warcraft (WOW) is perhaps the most egregious example in which lives have been and are continuing to be ruined.  The statistics will not be belabored here.  They are well presented in “Irresistible” along with numerous personal stories.  “Behavioral addiction” was discussed in a previous healthymemory blog post “Beware the Irresistible Internet.”  There is a series of posts based on Dr. Mary Aiken’s book, “The Cyber Effect” that has addressed this problem. Additional healthy memory posts on this topic can be found by entering “Sherry Turkle” into the search block of the healthymemory blog.  What is especially alarming is that Adam Alter makes a compelling argument that game makers are getting better at making their games irrestible, that is behaviorally addicting.

Of course, not all games are bad.  “Gamification”  is a term for games devoted to beneficial ends, such as education.  This can be very beneficial when learning, that could be tedious, is transformed into an entertaining game, which could be played for its entertainment value alone.  Good arguments can be made for these games provided that their educational benefits are documented.  However, even if it were possible, it would be dangerous if all of education were gamefied.  Not everything in life is enjoyable, and part of the educational process should be learning to assure the students persevere even when learning becomes difficult and frustrating.

Alter also does a commendable review of treatments for behavioral addictions and preventive measures to decrease the likelihood of addiction.  The book begins with Steve Jobs telling the New York Times journalist Nick Bilton that his children never used the iPAD, “We limit how much technology our kids use in theme.”  Bolton discovered that other tech giant imposed similar restrictions.  A former editor of “Wired,” Chris Anderson, enforced strict time limits on every device in his home, “because we have seen the dangers of technology firsthand.”  After relating the way tech giants controlled their childrens’ access to technology lAlter wrote, “It seemed as if the  people producing tech products were following the cardinal rule of drug dealing:  never get high on your own supply.”

Perhaps one of the most informative studies related in “Irresistible” is not specifically about addiction.  It related a paper published by eight psychologists in the journal “Science.”  In one study they asked a group of undergraduate students to sit quietly for twenty minutes.  They were told that their goal was to entertain themselves with your thoughts as best you can.  That is, your goal should be to have a pleasant experience, as opposed to spending time focusing on everyday activities or negative things.”  The experimenters hooked up  to a machine that administers electric shocks, and gave them a sample shock  to show that the experience of being shocked isn’t pleasant.   The students were told that they could self-administer the shock if they wanted to, but that “Whether you do so is completely up to you.”  It was their choice.
One student shocked himself one hundred and ninety times.  That’s once every six seconds, over and over for twenty minutes.   Although he was an outlier, two thirds of all male students and about one in three female students shocked themselves at least once.  Many shocked themselves more than once.  By their own admission in a questionnaire they didn’t find the experience pleasant, so they preferred to endure the unpleasantness  of a shock to the experience of sitting quietly with their thoughts.

Upon rereading this experiment HM became convinced that the teaching of mindfulness and meditation should be mandatory in the public school.  If so these students would have taken advantage of the situation to be “in the present ” and to meditate, just as they would if they found themselves stuck in traffic or being forced to wait.  (See the healthy memory blog post, “SPACE”)

Perhaps HM is a “goody two-shoes” but he has never been attracted to games.  He never cared how much he scored on a pin ball machine.  He is the same with respect to computer games.  They strike him as pointless activities, so he never plays them.

It strikes HM that public education is avoiding a key responsibility.  Students need to understand from an early age that their time on earth is limited.  This should not send them into panic or to avoid enjoyable pursuits.  But a question should be asked regarding any pursuit is what value does the pursuit have.  It is okay for some pursuits to be pursued for enjoyment alone.  But there are also pursuits, which in addition to being enjoyable, provide both personal benefits as well as societal benefits.

Ideally one should pursue a life with purpose as was related in the posts on Victor Strecher’s book “Life on Purpose.”  This provides for a benefiting an fulfilling life.  In the healthymemory blog post “SPACE” Stretcher argues for pursuing a healthy lifestyle to further the ends of living a life with purpose.

Inside knowledge: What’s Really Going On in the Minds of Animals

April 11, 2017

The title of this post is identical to the title of a Feature article by Michael Brooks in the Features section of in the 1 Apr 2017 New Scientist.   The article begins, “Bright animals from chimps to crows know what they know and what others are thinking.  But when it comes to abstract knowledge, the picture is more mixed.”  Some qualifications need to be placed on “what others are thinking.”  There are definite limits as we humans often have difficulty trying to know what our fellow humans are thinking.

The article also fails to note “The Cambridge Declaration of Scientists.”  It begins as follows:
“On this day of July 7, 2012, a prominent international group of cognitive neuroscientists, neuropharmacologists, neurophysiologists, neuroanatomists and computational neuroscientists gathered at the University of Cambridge to reassess the neurobiological substrates of conscious experience and related behaviors in human and non-human animals. While comparative research on this topic is naturally hampered by the inability of non-human animals, and often humans, to clearly and readily communicate about their internal states, the following observation can be stated unequivocally:”

and concludes:
“The absence of neocortex does not appear to preclude an organism from experiencing affective states. Convergent evidence indicates that non-human animals have the neuroanatomical, neurochemical, and neurophysiological substrates of conscious states along with the capacity to exhibit intentional behaviors. Consequently, the weight of evidence indicates that humans are not unique in possessing the neurological substrates that generate consciousness. Non-human animals, including all mammals and birds, and many other creatures, including octopuses, also possess these neurological substrates.”

The full statement can be found at http://fcmconference.org/img/CambridgeDeclarationOnConsciousness.pdf

Fortunately, the scientists here are neuroscientists, which gives the statement more gravitas than had it been made by psychologists.  But psychologists are involved in designing experiments to assess how much and what kinds of abstract knowledge can be achieved by different species.  And there is a long row of research ahead of them.  HM was much encouraged by this declaration as he has long thought that dogs were man’s best friend, rather than men being man’s best friend, because dogs had the neurological substrates for love and loyalty, but were lacking in neocortex that allowed for rationalization and deviousness.

There is a tendency to evaluate what animals know with respect to what humans know.  Sometimes this research seems to reflect an inferiority complex in showing what these are things we can do that nonhuman species cannot. They also need to be evaluated with respect to the capabilities of the species and the environments in which they operate.

We need to consider species with respect to their sensory caoacities. Consider are best friend, dogs, for example.  The vision of most dogs is not that good, but their hearing is outstanding, and their sense of smell is extraordinary.  When we think of someone, we tend to see them in our mind’s eye.  However, when a dog thinks of a person it is likely in terms of how that person smells.

Recent research has indicated that non-human species are more human than has traditionally been thought.  This research is to be applauded.  We look forward to what we’ll learn from future research, but it should go beyond what they can do compared to what we can do.

Inside Knowledge: Why Knowing Thyself is the Hardest Thing

April 10, 2017

The title of this post is identical to a Feature article by Anil Ananthaswamy in the 1 April 2016 issue of the New Scientist.  As Anil writes, We are within ourselves, so any attempt to build a full picture is fraught with our own cognitive biases and problems of self-reference.  Moreover a big part of our self perception is tied up with how others see us, yet we can never now the biases that cloud their perception.

Philosophical investigation and scientific observation of human behavior allow us to delineate the question of what the self is a little more sharply.  There are several ways of doing this.

There is the phenomenal self.  This corresponds to our signs of existing, and that there is a distinct entity in our mind that experiences this existence.  The self is very real to each of us:  it’s a sense of being a body situated in the here and now, and also of being a person existing over time.  Unfortunately, this is not always a reliable source of true knowledge.  There is a rate neurological disorder Cotard’s syndrome in which the individual has the distinct and disturbing experience of non existence—a  subjective self-knowledge clearly at odds with the truth.  There are also people who do not feel that parts of their bodies, say particular limbs, are not theirs.  And when we dream we have a robust sense of self while being completely deluded about who and where we are.

The epistemic self is a more sophisticated type of self-knowledge.  The epistemic self is a sense of self that knows it knows.  The epistemic self is aware of the working of the phenomenal self, and can make us more aware of our motivations.  It is a new way of relating to oneself.

Imagine you are sitting in a mind-numbing meeting and start fantasying about an exotic vacation.  Your phenomenal self wanders with you into this dream world, but as you snap back to the reality of your meeting and become aware you’ve been daydreaming, your epistemic self flashes into action, only to disappear again as you mind focuses (or wanders) once more.

The aim of mindfulness and meditation is to enhance the epistemic self.  Doing so gives us greater mental autonomy, “the capacity to stop or better control what we’re thinking, feeling, and doing.”  There are many healthy memory posts on mindfulness and meditation.

Inside Knowledge: The Maximum Any One Person Can Ever Know

April 9, 2017

The title of this post is identical to the title of a Feature Article by Sean O’Neill in the 1 April 2017 issue of the New Scientist.  The preceding post explained why Homo Sapiens will never know everything.  This post estimates the maximum any one person can know.

A human brain has approximately 100 billion neurons connected in labyrinthine ways by 100 trillion synapses.  According to a 2015 estimate from the Salk Institute, this amounts to an information storage capacity measured in petabytes, which are millions of gigabytes.  In comparison the Large Hadron Collider, the particle smasher as CEN, pumps out some 30 petabytes of data in use one year.  A recent paperer published jointly by researchers using the collider credited 5000 people with producing and analyzing the data.

Of course creating knowledge is about a lot more than assimilating data.  Our brains are not an empty petabyte stick.  As O’Neill notes, if it were, you would send it back to the shop, disappointed in its slow upload rate.

What is relevant is how much an individual brain can know as we have never filled one up.  We reach a time limit before we reach a processing limit.  Hyperpolyglot Alexander Arguelles is already competent in over 50 languages.  He says, “Give me total freedom of time…and I could conceivably do 100 languages.”  O’Neill notes that this would be at the expense of everything else.

Cesar Hidalgo of the Massachusetts Institute of Technology has dubbed the amount a person can realistically learn in a lifetime a personbyte.   He notes that the knowledge you would need to throw a beautiful clay pot is less than 1 person byte.  But if you want to build an F-22 Raptor fighter jet complete with on-board missile-guidance systems, you’re going to need many thousands of person bytes.

O’Neill optimistically concludes that “we should not let our brains meagre bandwidth get us down.  And if the amount and complexity of human knowledge has increased over time, so the means of acquiring it have steadily improved too, with spoken knowledge, written language, the printing press and now the internet.  In that profusion of information, the barrier to progress lies not in the quantity of knowledge our brains can hold, but in its quality.”

Although what O’Neill writes is true, especially in putting the emphasis on the quality of knowledge instead of the quantity, we still need to be humble about how much we think we know.  HM writes “think we know” because we can never be sure of what we know.  Regardless of the technology, there are biological limits to the rate of knowledge acquisition and the capacity of short term memory.  So we need to walk and talk humbly.

Inside Knowledge: Why We’ll Never Know Everything

April 8, 2017

The title of this post identical to the title of an article by Richard Webb in the Features Section of the 1 Apr 2017 New Scientist.   There are many limitations, but let us just consider computational power.  One can argue that computational power is only a temporary limitation.  Webb notes, however powerful we make them, computers rely on human input to program them.

Webb goes on to comment “…human thought is a glorious, uproarious, complex mess. Statements like “this statement is false, hating someone yet loving them and yes, that small-yet-large jumbo shrimp, both compute and do not compute.”  Panofsky, an information scientist at the City University of New York says, “language is an expression of the mind, and my mind is full of contradictions.”

This flexibility allows us to think creatively, while remaining firmly grounded.  Webb says that “because we are predicated on contradiction, we see contradiction everywhere. But “the defining feature of reality is that it admits no contradiction.   Quantum objects apparently act as waves or as particles depending how we choose to measure them.”  Physicist Richard Feynman called this confusing duality “the only mystery” of the quantum world.  Webb conjectures, “In all probability, the basic building blocks of reality are neither wave nor particle, but something else entirely.  It’s just something that we lack the experience or cognitive ability to express.”

When HM was a naive undergraduate he did not want to waste time on philosophy courses where questions were raised, solutions were presented and argued about, but resolution or general agreement, was never achieved.  So he took courses in symbolic logic where, he thought, definitive conclusions could be reached.  Logic and mathematics is supposedly a cleaner, neutral language for a trained brain to describe in abstract terms what it cannot visualize.  What HM learned in symbolic logic was that there were logical limitations on both logic and mathematics.

For example, there is the well-known injunction that you should never divide a number by zero.  If you do, you can begin to do things like prove 1 = 2.  This can’t be allowed if mathematics are the language of a flawless universe.   Panofsky says, “if you want mathematics to continue without contradiction than you have to restrict yourself.”

Kurt Godel showed in the 1930s that any system of logic containing the rules of arithmetic is bound to contain statements that can be neither proved nor disproved.  It will remain “incomplete” , trapped in the same inconsistency as we are.  Model incompleteness is a mathematical expression of the logical-illogical statement “this statement is false.”  So there is no way for anything, be it a simple sentence, system of logic, or a human being to express the full truth about itself.

Webb continues “This problem of self-reference is endemic.  Godel’s contemporary Alan Turing showed that you cannot ask a computer program in advance whether it will run successfully.  Quantum mechanics sprouts paradoxes because we are part of the universe we are trying to measure.”

And Webb concludes, “So the sobering truth is that we can build the most powerful telescopes, microscopes and computers we want, we we will never overcome the limitations of our minds.  Our perspective on reality will always be skewed because we—and the jumbo shrimp—are part of it.”

Inside Knowledge: How to Tell Truth from Lies

April 7, 2017

The title of this post is identical to the title of an article by Tiffany O’Callaghan in the Features section of the 1 Apr 2017 New Scientist.  This article notes there are hardcore relativist philosophers who argue that there’s no such thing as objective truth that exists outside our minds.  This is absurd.  What they might be intending to mean, and is something that HM thinks, is that we shall never find objective truth (see the immediately preceding post that follows this one, blog style).  Science is a systematic method for achieving an increasingly better understanding of objective truth.  The risk in believing that one has objective truth is the same as having beliefs having certainty.  They blind us to other better options.

Very often in both science and math, simplifying assumptions are made to make the research problem tractable.  These simplifying assumptions are necessary and bring us closer to objective truth.  However, it must always be remembered that these results were obtained using simplifying assumptions.

Unfortunately, we live in a world in which there are businesses devoted to making lies (see the healthy memory blog post, “Lies, Inc.”).

Steve Sloman says that as individuals, we hardly know anything.  “But most of us do very well, and as a society we create incredible things.  We sent  a person to the moon.  How is this possible”?  Because of the knowledge of other people.”

The article presents the following advice for treading the fine line between healthy skepticism and destructive cynicism.  “First, think critically and assess the credentials, track record and potential bias of the sources we rely on.” wrote Peter van Inwagen. He continues, “If someone is telling me this, what motives could that person have for wanting me to believe that, other than that it’s true?”

We should ask how do we know?  How do they know? We need to ask ourselves whether our reaction to new knowledge is rooted in something trustworthy or something else, like wishful thinking.  Those not believing in global warming in spite of scientific evidence might require them to do a certain amount of rather inconvenient stuff, stuff that would have financial costs, so they really rather not believe and start to make the sacrifices we would all have to make.

Inside Knowledge: What Makes Scientific Knowledge Special

April 6, 2017

The title of this post is identical to an article by Michael Brooks in the Features Section of the 1 Apr 2017 New Scientist.   The article begins, “NULIUS in verba:  “take nobody’s word for it”.  This is the motto of the Royal Society, the UK’s national academy of science.  This encapsulates the spirit of scientific inquiry.  The article continues, “Thanks to what science tells us about human physiology, the universe’s history, nature’s forces and Earth’s geology, flora and fauna, we know the earth isn’t flat, the universe is nearly 14 billion years old, and that there are no dragons or unicorns.  We live longer and in more comfort, and can send space probes to the edge of the universe.

But there are people who still contend the earth is flat.  Other people say the universe is 6000 years old.  Still others doubt the the theory of evolution by natural selection.  And there are people who question the reality of human-made climate change.  Unfortunately, some of these people are in positions of power like Donald Trump and his appointees.  For this, HM apologizes to the rest of the world.  However, a majority of the American voters did not vote for Trump.  Trump did not win the popular vote. He was elected by an electoral college, an institution developed to deny the principle of one citizen, one vote.

What is worse is there is an industry devoted to publishing and promoting scientific lies (see the healthy memory blog post, “Lies, Inc).  It needs to be understood that the scientific facts cited above could change.  Science is always an approximation of the truth.  Absolute truth is a destination we will likely never reach.  But to change science, experiments that produce data are required.  And there must be a means of disproving scientific theories.  There must be a way of disproving creationism, or it is not a scientific theory.  And there are arguments that question human-made climate change.  Unfortunately, some of these arguments come from Lies, Inc.  However, to be fair, there are scientists who question not the effects of humans on climate change, but on the rate at which these effects are taking place.  In this case, the opinion goes to the majority of research that argues climate change is real and is increasing at an alarming rate.

Philosopher Edward Hall of Harvard says “Authority in science is earned—at least, when a scientific community is functioning well—by  predicting and more generally at analyzing empirical phenomena.”

Inside Knowledge: Why We Like to Know Useless Stuff

April 5, 2017

This blog post has the same title as a Feature article by Daniel Cossins in the 1 Apr 2017 New Scientist. The author notes that knowledge is more than just information.  “Even the nematode worm caenorhabditis elegant, the owner of one of the smallest brains we now, forages to maximize information about its environment, and so its chances of staying alive and reproducing.”  This is the typical analysis offered by scientists.  It seems like the entire point is for species to evolve and to reproduce.  However, evolution offers the hope that we can evolve into something better.  Homo sapiens as a whole is quite depressing.  We seem to be preoccupied with warfare and have developed weapons that can lead to our own extinction.  However, there are some members of our species who espouse transcendental values, which leads to the hope that we might become something better.

Cousins writes, “The precise details of how we first came to love knowledge may always elude us.  But it is easy to see how it would have spurred our success as individuals and as a species furnishing us with the tools—often literally, if you think of  cutting blades or fire—to survive and prosper.”

So the argument is that we are addicted to knowledge because it has served us so well in the past.  It still does today, in everyday life as well as the frontiers of technological progress.  The term infovores has be used to describe this propensity (enter “infovores” into the search block of the healthy memory blog).

Abraham Flexner, the founder of the Institute of Advanced Study (IAS) at Princeton pointed out in a 1939 essay “The usefulness of useless knowledge,” radio communications and all that came with it wasn’t ultimately the inventions of Guglielmo Marconi.  It was down to James Clerk Maxwell and Heinrich Hertz, scientist who worked out the basics of electromagnetic waves with no practical objectives.”

The current director of IAS, Robbert Dijkgraaf has written a companion essay to a reissue of Flexner’s original.  He wrote, “The theory of general relativity is used every day in our GPS systems, but it was not the reason Einstein solved it.

The problem is that too many people reject science.  Some reject science on the basis of religious texts.  Others are fundamentally ignorant.  What is most depressing is the leader of the United States rejecting scientific research.  For this HM apologizes.  Although he did not win the popular vote; he was chosen by the electoral college, an anachronism that denies the sacred principle of one citizen, one vote.

Inside Knowledge: What Separates Fact from Belief

April 3, 2017

The title of this post is identical to an article by Richard Webb in the Features Section of the 1 Apr 2017 New Scientist.  HM answers this question by saying that it is the degree of belief.  Research has indicated that absent any indications to the contrary when we hear or see a fact, the default is to believe it.  When supposed facts are heard or read that do not correspond to the individual’s belief system, a noticeable signal is recorded in the brain.  This indicates that System 2 thinking has been invoked and this fact will either be rejected or postponed until further information and thinking can be performed.  Kahneman terms System 1 intuition and System 2 reasoning.  System 1 is fast, that’s why it’s the default processing system.  System 2 is slow and requires further thinking.  System 2 is supposed to protect us from false beliefs.  At the turn of he 20th century there were many physical scientists who believed that practically everything that needed to be known about the physical sciences was known.  All that was needed was to add some more decimal places of precisions.  Just five years later Albert Einstein published his Special Theory of Relativity.  Beliefs should always be subject to change and should never reach certainty.

Technology has developed at such an alarming rate that there are an enormous number of facts to evaluate.  All of science, both physical and social, is producing facts that lay people do not have the knowledge to evaluate. Moreover, there is a business of deliberately publishing false facts (See the healthy memory blog post, “Lies, Incorporated.”)

The remainder of this post is motivated by the box titled “Where Knowledge Comes From”  at the bottom of the article.  One way of classifying knowledge is by how we acquire it.

Perceptual knowledge comes from our senses but involves significant processing by our brains.  Basically the brain builds models of the world using this information, but it must be appreciated that we do not have direct knowledge of the world.  The truth is that we infer it, and this knowledge changes as information grows.  Everyone should be familiar with perceptual illusions, in which the psychological interpretation does not agree with the physical representation.

Testimonial knowledge comes from other people and media.  Here belief should largely hinge on the source of the information.  Different sources have different biases, as these biases must be taken into consideration.  The credentials of the sources are of primary importance.  Whether there is scientific evidence for the facts is especially important.  Sources that contradict scientific data must be evaluated with skepticism.

Our inner sense, the awareness of our own feelings and states, such as pain and hunger would appear to be highly credible, but some times we are out of touch with our senses.  Beliefs can actually greatly deaden pain in many cases.  Enter “placebos”  into the search block of the healthy memory blog.  (Enter “placebos” into the search block of the healthy memory blog to learn more about their effectiveness)

Inferential knowledge goes beyond actual facts in assessing the credibility of facts, and in making inferences about facts.  Critical thinking is key here.

Beliefs can blind us to facts.  A good example of this is the problem of health care in the United States.  Health care in the United States is the most expensive in the world, yet health statistics in the United States approach those in the third world.  Every advanced country in the world has a national system of health care except the United States.  The reason for this is that the Republican party sees government as the problem and not the solution to health care.  But all other advanced countries have successful health care systems in which the governments play a central part.  The affordable health care act, frequently referred to as Obamacare, used the government to increase access to health care.  It was a small effort that fell far short of Obama’s goals.  Trump promised that Trumpcare would be much better than Obamacare.  Had he formulated an improvement over the affordable care act, it would have been welcome.  However, the plan that was formulated was woefully short of the Affordable Care Act, and was defeated.

Republicans trumpet the value of market forces in health care.  But back in 1963 Nobel Prize winning economist Kenneth Arrow offered an explanation as to why markets do not work well in health care.  There is a huge mismatch of power information between the buyer and seller.  For example, if a salesman tells us to buy a particular television, we can easily choose another or just walk away.  However, if a doctor insists we need a medication or procedure, we are far less likely to reject the advice.  Arrow also noted that people don’t think they don’t need health care until they get sick, and then they need lots of it.

Beliefs are frequently compartmentalized and this has adverse effects on inferential knowledge.  Here again the Republican Party and healthcare provide a good example.  It should be understood that both parties have religious beliefs, but Republicans are especially strong in their beliefs which center on loving our neighbors, and caring for the needy and sick.  Yet compartmentalization of the Republican beliefs about the role of government blocked addressing religious beliefs about caring for the sick  with the result of increased unnecessary suffering among their fellow human beings

Beliefs are necessary, but they should never be absolute.  They are dangerous in that they can foreclose meaningful solutions to critical problems.  And they can hinder effective inferential knowledge.  A useful exercise is occasionally to try to ignore one’s beliefs and explore the ramifications of ignoring those beliefs.

Pedestrian Deaths Soar in the Uneven Battles with Cars

April 2, 2017

The title of this post is identical to the title of an article written by Ashley Halsey III in the 30 March 2017 issue of the Washington Post.  Pedestrian deaths soared by 25% nationally between 2010 and 2015.  Pedestrians now account for 15% of all traffic deaths.  Preliminary data for 2016 indicate that a the number of pedestrian deaths increased by 11% over 2015, with 6,000 people being killed in collisions with vehicles.  A number of reasons for this increase were noted, but the one that caught HM’s eyes was the use of smartphones—both by drivers and people on foot.

The article includes engineering and safety measures that need to be undertaken to reduce pedestrian deaths.  HM applauds these efforts, but this post is devoted to the measures pedestrians need to take to protect themselves.

The first is to not use smartphones, both as drivers and pedestrians.   Many, many healthy memory posts have been written on the dangers of distracted driving.  The personal risks to smartphone use by pedestrians are even greater.  I’ve seen pedestrians walking, engrossed in their smartphones, who step into traffic without checking for oncoming vehicles.  The HM has almost hit several of these pedestrians.  Fortunately he did not.  But an accident with one of these pedestrians would have haunted him for the rest of his life even though he would not have been at fault.

There are a couple of reasons pedestrians might be so careless.  One is that they have never ever been hit by a vehicle, so they think vehicles are not going to hit them.  What they fail to realize is that drivers certainly do not want to hit drivers, but drivers need to be given sufficient time to respond to avoid a collision.

Pedestrians also seem to assume a symmetry between their perception of automobiles and the automobile drivers’ perception of them.  This problem is particularly acute at night.  Although it is easy for pedestrians to see cars with their blazing lights, pedestrians are small usually dressed in dark clothing, which can make them almost impossible to see.

When HM was in public schools there were posters that were prominently displayed, “Where white at night.”  What has happened to these signs?  They need to be resurrected and placed in many prominent places.  Today reflectors are more readily available, but why don’t pedestrians make more use of them?

Perhaps Tim Berners-Lee Did Not Anticipate This Problem

April 1, 2017

And this problem can be found in a front page article by Elizabeth Dwoksin and Crain Timberg titled “Advertisers find it hard to avoid sites spawning hate” in the 25 March 2017 issue of the Washington Post.

This article begins, “As the owner of a small business in liberal Massachusetts, John Ellis was a natural sympathizer of the nationwide call for advertisers to boycott Breitbard News, with its hard-edge conservative politics and close ties to President Trump.  But it made Ellis wonder about other more extreme right-wing sites:  Who is placing adds on them?  A few clicks around the Internet revealed a troubling answer:  He was.”

He found an add for his engineering company company, Optics for Hire, on a website owned by white nationalist leader, Richard Spencer.  Of course, this meant that he was unknowingly supplying funding for this website.

The Post article continues that  in the booming world of Internet advertising, businesses use the latest in online advertising technology offered by Google, Yahoo, and their major competitors are increasingly finding their ads placed alongside politically extreme and derogatory content.

The reason for this is that the ad networks offered by Google, Yahoo, and others can display ads on vast numbers of third-party websites based on people’s search and browsing histories.  This strategy gives advertisers an unprecedented ability to reach customers who fit a narrow profile; it dramatically curtails their ability to control where their advertisements appear.

This week AT&T, Verizon and other leading companies pulled their business from Google’s AdSense network in response to news report that ads had appeared with propaganda from the Islamic State and violent groups.

A Washington Post examination of dozens of sites with politically extreme and derogatory content found that many were customers of leading ad networks, which share a portion of revenue gleaned from advertisers with the site’s operators.  The examination found that the networks had displayed ads for Allstate, IBM, DirectTV and dozens of other household brand names on websites with content containing racial and ethnic slurs, Holocaust denial and disparaging comments about African Americans, Jews, women, and gay people.

Other Google displayed ads, for Macy’s and the genetics company 23andMe, appeared on he website My Posting Career, which describes itself as a “white privilege zone,” next to a notice saying the site would offer a referral bonus for each member related to Adolph Hitler.

Some advertisers also expressed frustration that ad networks had failed to keep marketing messages from appearing alongside reader comments—even on sites that themselves do not promote extremist content.

Clearly more attention needs to be devoted to this topic along with better screening algorithms.  And perhaps some companies will need to make a choice between profits and offending content.
