How Do You Think?

Have you ever heard someone make an argument that leaves you shaking your head in disbelief?  Does it seem to you like some people are coming from a completely different reality than your own?  If so, then this blog is for you.  I have spent the last year trying to develop an understanding of the common thought patterns that drive the acrimonious spirit of our social and political dialogue.  I am continually amazed by what I hear coming from seemingly informed people.  I have assumed that some folks are either deluded, disingenuous, or downright ignorant.  There is yet another possibility here, including the reality that different moral schema or belief systems may be driving their thinking.  And if this is the case, how do these divergent processes come to be?  I  have learned a lot through this exploration and feel compelled do provide a recap of the posts I have made.  I want to share with you those posts that have gathered the most traction and some that I believe warrant a bit more attention.

Over the past year I have posted 52 articles often dealing with Erroneous Thought Processes, Intuitive Thinking, and Rational Thought.  Additionally, I have explored the down stream implications of these processes with regard to politics, morality, religion, parenting, memory, willpower, and general perception.  I have attempted to be evidenced-based and objective in this process – striving to avoid the very trappings of confirmation bias and the erroneous processes that I am trying to understand.   As it turns out, the brain is very complicated: and although it is the single most amazing system known to human kind, it can and does lead us astray in very surprising and alarming ways.

As for this blog, the top ten posts, based on the shear number of hits, are as follows:

1. Attribution Error
2. Nonmoral Nature, It is what it is.
3. Multitasking: The Illusion of Efficacy
4. Moral Instinct
5. Pareidolia
6. IAT: Questions of Reliability
7. Are You a Hedgehog or a Fox?
8. What Plato, Descartes, and Kant Got Wrong: Reason Does not Rule
9. Illusion of Punditry
10. Emotion vs.Reason: And the winner is?

What started out as ramblings from a curious guy in a remote corner of New York State ended up being read by folks from all over the planet.  It has been a difficult process at times, consuming huge amounts of time, but it has also been exhilarating and deeply fulfilling.

I have been heavily influenced by several scientists and authors in this exploration.  Of particular importance have been Steven Pinker, Daniel Simons, Christopher Chabris, Jonah Lehrer, Bruce Hood, Carl Sagan, and Malcolm Gladwell.  Exploring the combined works of these men has been full of twists and turns that in some cases necessitated deep re-evaluation of long held beliefs.  Holding myself to important standards – valuing evidence over ideology – has been an important and guiding theme.

Several important concepts have floated to the top as I poked through the diverse literature pertaining to thought processes. Of critical importance has been the realization that what we have, when it comes to our thought processes, is a highly developed yet deeply flawed system that has been shaped by natural selection over millions of years of evolution.  Also important has been my increased understanding of the importance of genes, the basic element of selective pressures, as they play out in morality and political/religious beliefs.  These issues are covered in the top ten posts listed above.

There are other worthy posts that did not garner as much attention as those listed above.  Some of my other favorites included a review of Steven Pinker’s article in the New York Times (also titled Moral Instinct,) a look at Jonathon Haidt’s Moral Foundations Theory in Political Divide, as well as the tricks of Retail Mind Manipulation and the Illusion of Attention.  This latter post and my series on Vaccines and Autism (Part 1, Part 2, Part 3) were perhaps the most important of the lot.  Having the content of these become general knowledge would make the world a safer place.

The evolution of understanding regarding the power and importance of Intuitive relative to Rational Thinking was humbling at times and Daniel Simons’ and Christopher Chabris’ book, The Invisible Gorilla, certainly provided a mind opening experience.  Hey, our intuitive capabilities are incredible (as illustrated by Gladwell in Blink & Lehrer in How We Decide) but the downfalls are amazingly humbling.  I’ve covered other topics such as  happiness, superstition, placebos, and the debate over human nature.

The human brain, no matter how remarkable, is flawed in two fundamental ways.  First, the proclivities toward patternicity (pareidolia), hyperactive agency detection, and superstition, although once adaptive mechanisms, now lead to many errors of thought.  Since the age of enlightenment, when human kind developed the scientific method, we have exponentially expanded our knowledge base regarding the workings of the world and the universe.  These leaps of knowledge have rendered those error prone proclivities unessential for survival.  Regardless, they have remained a dominant cognitive force.  Although our intuition and rapid cognitions have sustained us, and in some ways still do, the everyday illusions impede us in important ways.

Secondly, we are prone to a multitude of cognitive biases that diminish and narrow our capacity to truly understand the world. Time after time I have written of the dangers of ideology with regard to its capacity to put blind-folds on adherents.  Often the blind- folds are absolutely essential to sustain the ideology.  And this is dangerous when truths and facts are denied or innocents are subjugated or brutalized.  As I discussed in Spinoza’s Conjecture:  “We all look at the world through our personal lenses of experience.  Our experiences shape our understanding of the world, and ultimately our understanding of [it], then filters what we take in.  The end result is that we may reject or ignore new and important information simply because it does not conform to our previously held beliefs.

Because of our genetically inscribed tendencies toward mysticism and gullibility, we must make extra effort in order to find truth. As Dr. Steven Novella once wrote:

“We must realize that the default mode of human psychology is to grab onto comforting beliefs for purely emotional reasons, and then justify those beliefs to ourselves with post-hoc rationalizations. It takes effort to rise above this tendency, to step back from our beliefs and our emotional connection to conclusions and focus on the process.”

We must therefore be humble with regard to beliefs and be willing to accept that we are vulnerable to error prone influences outside our awareness.  Recognition and acceptance of these proclivities are important first steps.   Are you ready to move forward?  How do you think?

I don’t know if you caught it the other night when you were watching the news while skimming your email, checking your twitter and RSS feeds, and updating your Facebook status, but there was an interesting story about multitasking.  Silly me, who actually watches the news anymore? Anyways, much of the recent buzz on this endemic behavior (among the technologically savvy) is not good.  Multitasking is a paradox of sorts – where we tend to romanticize and overestimate our ability to split attention among multiple competing demands. The belief goes something like this: “I’ve got a lot to do and if I work on all my tasks simultaneously I’ll get them done faster.”   However, what most of us fail to realize is that when we split our attention, what we are actually doing is dividing an already limited and finite capacity in a way that hinders overall performance. And some research is showing that chronic multitasking may have deleterious affects on one’s ability to process information even when one is not multitasking (Nass, 2009).

Advances in computer technology seem to fuel this behavior.  If you do a Google search on multitasking you will get a mix of information on the technological wonders of machines that can multitask (AKA computers) mixed with news regarding how bad media multitasking is for you.

Think about it.  There has been increasing pressure on the workforce to be more productive and gains in productivity have been made lockstep with increases in personal computing power. Applications have been developed on the back of the rising tide of computer capacity, thus making human multitasking more possible.  These advances include faster microprocessors, increased RAM, increased monitor size, the internet itself, browsers that facilitate the use of multiple tabs, relatively inexpensive computers with sufficient power to keep open email, word processing programs, Facebook, Twitter, iTunes, and YouTube. Compound these tools with hardware that allows you to do these things on the go. No longer are you tethered to the desktop computer with an Ethernet cable.  Wifi and 3G connectivity allow all the above activities almost anywhere via use of a smart phone, laptop, iPad, or notebook computer.  Also in the mix are devices such as bluetooth headsets and other headphones that offer hands free operation of telephones.

Currently, technology offers one the ability to divide one’s attention in ways inconceivable only a decade ago. The ease of doing so has resulted in the generalization of this behavior across settings and situations including talking on cell phones while driving, texting while driving, texting while engaged in a face to face personal interactions, and even cooking dinner while talking on the phone. Some of these behaviors are dangerous, some rude, and all likely lead to inferior outcomes.

Don’t believe it? If you don’t, you are likely among the worst skilled of those who multitask. “Not me!” you may claim. Well research has shown that those who routinely multitask are also the most confident in their ability to do so (Nass, 2009).  But when you look at the products of these “confidently proficient” multitaskers, you find the poorest outcomes.

Multitasking involves shifting attention from one task to another, refocusing attention, sustaining attention, and exercising ongoing judgment about the pertinence and salience of various competing demands. Doing this successfully is exceptionally difficult and is likely well beyond the capacity of most typical human beings. Our brains can only generally concentrate on one task at a time, and as such, multitasking necessitates devoting shorter periods of time on dissimilar tasks.  As a result, overall effectiveness, on all tasks is reduced.

Researchers at the University of Michigan Brain, Cognition and Action Laboratory, including Professor David E. Meyer, point out that the act of switching focus itself has deleterious effects. When you switch from task A to task B you lose time in making the transition and the completion time of the transition itself increases with the degree of complexity of the task involved. Depending on how often you transition between stimuli, you can waste as much as 40% of your productive time just in task switching (APA, 2006).

Shorter periods of focus reduce overall time on task and each transition reduces this time further. Dr. Glenn Wilson at the Institute of Psychiatry, University of London in 2005 discovered that his subjects experienced a 10-point fall in their IQ when distracted by incoming email and phone calls. This effect size was “more than twice that found in studies of the impact of smoking marijuana” and was similar to the effects of losing a night’s sleep (BBC, 2005).

As for the negative long term affects of multitasking, Dr. Nass noted that:

 

“We studied people who were chronic multitaskers, and even when we did not ask them to do anything close to the level of multitasking they were doing, their cognitive processes were impaired. So basically, they are worse at most of the kinds of thinking not only required for multitasking but what we generally think of as involving deep thought.”

Nass (2009) has found that these habitual multitaskers have chronic filtering difficulties, impaired capacity to manage working memory, and slower task switching abilities. One must be careful to avoid the Illusion of Cause in this situation. Correlation is not causation and we must avoid inferring that multitasking causes these cognitive declines. The reverse may be true or other undetected variables may cause both.

Much of the research in this area is in its infancy and thus limited in scope and depth, so it is prudent to be a bit skeptical about whether or not multitasking is bad for you. But with regard to the efficacy of multitasking – when you look at the issue from an anecdotal perspective, apply the tangentially related evidence logically, and then consider the data, you have to conclude that multitasking on important jobs is not a good idea.  If you have important tasks to accomplish, it is best to focus your attention on one task at a time and to minimize distractions.  To do so, avoid temptation to text, tweet, watch TV, check your email, talk on the phone, instant message, chat on Facebook, Skype, or otherwise divide you attention. If you believe employing these other distractions helps you do better, you are deluding yourself and falling victim to the reinforcement systems that make multitasking enjoyable. Socializing, virtually or otherwise, is more pleasurable than the arduous processes involved in truly working or studying.

You can likely apply the same principles to plumbing, cooking, housework, woodworking, etc.  The key to success, it seems is to FOCUS on one task at a time, FINISH the job, and then move one.  You’ll save time, be more efficient, and do a better job! Remember – FOCUS & FINISH!
