When Tribal Moral Communities Collide

Apr03
2011 2 Comments Written by Gerald Guild

When I hit the publish button for my last post Cognitive Conservatism, Moral Relativism, Bias, and Human Flourishing I felt a tinge of angst.  It took a few days for my rational brain to figure out (or perhaps confabulate) a reason; but, I think I may have.  Perhaps it should have been immediately obvious, but my outrage likely clouded my judgment.  Anyways, that angst wasn’t due to the potential controversy of the article’s content – I had previously posted more provocative pieces.  What I have come to conclude is that the nature of the controversy could be construed as being more personal.

It is not hard to imagine that there is a very real possibility that people I love may have been hurt by what I wrote.  This left me feeling like a hypocrite because what I have continually aspired to communicate is that “true morality” should promote human flourishing for everyone.  Although the overarching message was consistent with my goal, the tone and tenor was not.

I was inspired by a blog post written by a family member that touched the nerves of my liberal sensitivities.  Further, and more importantly, I believe that what he wrote was likely hurtful to others in my family.   A couple of my tribal communities (moral and kin) were assaulted, and I responded assertively.

The whole purpose of my blog “How Do You Think?“ has been driven toward understanding such diverse and mutually incompatible beliefs that do in fact transcend my family and the world in general.  In this particular situation, however,  I placed several family members in the crux of just such a moral juxtaposition.

I am certain that much of what I have written over the last year may be construed as offensive to some from a variety of different tribal moral communities.  But one thing I am equally certain of, is that attacking one’s core moral holdings is not an effective means of facilitating enlightenment.

I responded to my relative’s pontifications with moral outrage and indignation.  I was offended and mad.  That is what happens when core beliefs are challenged.  We circle the wagons and lash back.  But this does nothing to further the discussion.  I should have known better.  And, that error of judgment may have lasting familial consequences.  This saddens me, and I am sorry.

So then, how are we to cope with such diametrically opposed perspectives?

If you have consistently read my posts you are likely to have come away with an understanding of the workings of the human brain, and as such, realize that it is an incredible but highly flawed organ.   What is more important to recognize, is that these flaws leave us prone to a variety errors that are both universal and systematic.  The consequences of these errors include Confirmation Bias, Spinoza’s Conjecture, Attribution Error, Pareidolia, Superstition, Essentialism, Cognitive Conservatism, and Illusions of all sorts (e.g., Attention, Cause, Confidence, Memory, Efficacy, Willpower, and Narrative).  The down stream consequences of these errors, paired with our tribal nature, and our innate moral inclinations lead us to form tribal moral communities.  These communities unite around ideologies and sacred items, beliefs, or shared history’s.  Our genetically conferred Moral Instincts which are a part of our Human Nature lay the ground work for us to seek out others who share our beliefs and separate ourselves from others who do not.  This is how the divide occurs.  And our brain is instrumental in this division and the subsequent acrimony between groups.

This is perhaps the most important concept that I want to share.  Systematic brain errors divide us.  Understanding this – I mean truly understanding all of these systematic errors, is essential to uniting us.  Education is the key, and this is what I hope to provide.  Those very brain errors are themselves responsible for closing minds to the reality of these facts.  Regardless, the hopes that I have for universal enlightenment persist and I hope to endeavor ever onward opening minds without providing cause to close them.   I fear that I  have taken a misstep – spreading the divide rather than closing it.

Please know that Human Flourishing for all is my number one goal.  Never do I intend to come off as judgmental, hurtful, or otherwise arrogant or elitist.  When I do – please push back and offer constructive criticism.   We are all in this together – and time, love, life, peace, and compassion are precious.   This is the starting point – something that I am certain we share.  Don’t you think?

Cognitive Conservatism, Moral Relativism, Bias, and Human Flourishing

Mar26
2011 1 Comment Written by Gerald Guild

I am a caring and compassionate man with deep concerns about humanity.  Of utmost importance to me is the issue of human flourishing, which roughly translated, incorporates wellness, happiness, success, and adaptive functioning not only for the individual, but for society in general.  Individual flourishing necessitates societal flourishing and vice versa.  One does not rise at the expense of the other.  Promoting human flourishing has been my life’s work.

I see around me much acrimony, the source of which often ascends from moral inclinations from diverse cultures.  This concerns me, as one ought to suppose that morality should promote human flourishing.  Should it not instill virtue and wellness for all?  Unfortunately, the moral teachings of the world’s religions pitch one belief against another.  And it does not take much effort to see that virtually all ideologically based moral systems actually inhibit human flourishing for many.

At the core of these issues are several human inclinations that feed and sustain many of the perpetual conflicts that consume our blood and treasure and in other ways gravely harm our brothers and sisters.  Deeper still, at the root of many erroneous human inclinations, is a flawed brain that makes us vulnerable to ideology and likely to sustain beliefs without good reason.

Our brains sustain vestigial mechanisms that render us prone to all sorts of cognitive errors and illusions.  As a major consequence, we are inclined to hold on to belief systems regardless of substantive evidence to suggest that we just might be wrong.   This Cognitive Conservatism is a universal human attribute, and it plays out as we disregard, devalue, discredit, and/or out-write ignore evidence that contradicts previously held beliefs.  At the same time, we gladly take in evidence that confirms our beliefs.  This is an undeniable truth about the human condition.

Suffice it to say that our brains are belief engines leaving us vulnerable to mysticism and disinclined to accept aggregated evidence.  As such, our moral guidance has been historically guided by intuition (how things seem) as opposed to reason (how things actually are).  As a result, our intuitions in modern times are often wrong.  We tend to be compelled by anecdotes and stories rather than data.  We have relied on intuition and apparent correlations to guide us, and only recently has the scientific method entered our consciousness (circa 1400).

Another problematic inclination stems from our tribal tendencies.  Because of this we have developed a wide variety of diverse and often incompatible moral doctrines.  We have for fear of cultural insensitivity and accusation of bias, been pressured to accept as “moral” such atrocities as genital mutilation, genocide, and the demonization of homosexuality.  Although we might not view such acts as moral, the perpetrators certainly do.  This Moral Relativism, I believe is a grave error, particularly when you look at the subsequent consequences relative to human flourishing.

In some cultures it is acceptable to engage in honor killing.  For example, to torture, mutilate, or kill a female family member who has been a victim of rape is considered honorable.  Or consider martyrdom.  Suicide bombers fully believe that they are serving their God by killing infidels.  They further believe that they and 70 of their closest family and friends will be granted eternal bliss in the afterlife for doing God’s benevolent work.   Can we rightfully accept that either of these acts advances human flourishing?  Is it truly acceptable to condone either act because it is believed to be morally acceptable by their culture?  Is disapproving of these acts culturally insensitive or indicative of bias?

Using the same logic, is it acceptable to limit the expression of romantic love to only those that happen to be from the opposite sex?  Does rendering homosexuality illegal or immoral, promote or hinder human flourishing?  I suggest that it accomplishes the latter.  And are not the origins of the beliefs that render homosexuality wrong, wrought from the same belief mechanisms that encourage martyrdom or honor killings?

If I am driven to use evidence to guide decisions regarding what promotes or diminishes human flourishing, one has to ask the question: “Is science biased?”  I recently read articles by morality guru Jonathon Haidt who suggested that indeed this may be the case.  He didn’t really argue that the data rendered by Social Psychologists was flawed.  He simply argued that the scientists themselves (in the field of social psychology) are heavily skewed to the liberal left.  The problem I have with his argument is that scientists use evidence to guide their beliefs, and as such, end up sharing liberal inclinations.  Does that render them biased?   I believe not.  There is a substantial difference between those that base their beliefs on evidence and those that base their beliefs on ideology.  It is more true to say that ideologues are biased because their beliefs that are unprovable and generally devoid of any real evidence.  This, I believe, is far more dubious.

Speaking of bias, I recently read an article written by a Roman Catholic Priest that derided National Public Radio (NPR) as being biased on par with right wing conservative media outlets.  The context of the argument was NPR’s inclination to cover the issue of homosexuality in a way that condoned it.  Because the author holds the belief that homosexuality is immoral, and NPR comes off as pro gay marriage (as well as taking other pro “liberal” positions), the author suggests that NPR, as an institution, is biased.  I could not disagree more with this notion.  NPR may have a liberal slant, but this does not automatically imply that it is biased.  I would argue that at NPR there is a stronger inclination to use evidence-based, rather than ideologically-based reason to guide its reporting.  Isn’t that what reporters are supposed to do?  Somehow, because the evidence does not support the moral inclinations of the church, or those of social conservatives, it is biased?  I think not!

This accusation of bias is wrong at a profoundly deep level!  Even if 90% of scientists are secular liberals, that does not render the facts that they expose as biased.  There is only one truth – and if the truth does not fit one’s beliefs, that doesn’t render it less truthful.  Moral relativism opens the door to multiple truths and renders evidence meaningless.  If we condone such thinking, then who are we to judge those who brought down the World Trade Center towers as “evil doers?”

Likewise, who are we to diminish the quality of life of a small but no less significant portion of our population because they happen to be born gay, lesbian, or bisexual?  Within consenting relationships, does gender really matter?  Can it be argued that making same sex intimacy illicit, diminishes human flourishing?  Yes it can, and it most definitely does!

When ideology crosses a line that diminishes human flourishing it has gone too far.  I am reminded of what I wrote in Surprise Chautauqua after listening to Bishop John Shelby Spong.

“Spong derides religious zealots who promote racism, sexism, antisemitism, and homophobia based upon quotations from the Holy Scriptures.  His rational embrace of science and the realities of human suffering (often as a result of religion’s influence) have guided his journey toward a reinterpretation of the faith story.  He strongly asserts that he wants nothing to do with any institution that diminishes the humanity of any child of God. He deplores how the Bible and the Church have harbored those that have relegated blacks to subhuman status, women as second class citizens, and gay and lesbian people as essentially immoral.”

I am incensed when religious doctrine results in human suffering. This is particularly true with regard to the Catholic Church who squandered any hope of offering moral guidance with regard to sexuality when it systematically aided and abetted pedophiles.   The Catholic Church should be granted no more moral authority than radical Islam. Their respective track records with regard to promoting human flourishing are abysmal. Only when we have the courage to stop turning a blind eye toward social injustice and stop condoning systematic human degradation (because it is consistent with a religious “moral” teaching) will all of humanity be able to truly thrive.

Vaccines and Autism

Aug13
2010 5 Comments Written by Gerald Guild

It is hard to imagine anything more precious than one’s newborn child. Part of the joy of raising a child is the corresponding hope one has for the future. Don’t we all wish for our children a life less fraught with the angst and struggles we ourselves endured? One of the less pleasant aspects of my job has the effect, at least temporarily, of robbing parents of that hope. This erosion occurs in the parent’s mind and heart as a consequence of a diagnosis I often have to provide. I am a psychologist employed in part to provide diagnostic evaluations of preschool age children suspected of having Autism. My intention is never to crush hope, instead it is to get the child on the right therapeutic path as early as possible in order to sustain as much hope as possible. However, uttering the word AUTISM in reference to one’s child constitutes a serious and devastating emotional blow.

Many parents come to my office very aware of their child’s challenges and the subsequent implications. They love their child, accept him as he is, and just want to do whatever they can to make his life better. Others come still steeped in hope that their child’s challenges are just a phase or believing that she is just fine. Regardless, most of them report that they suspected difficulties very early in the child’s development. For example, many note a lack of smiles, chronic agitation and difficulty soothing their child. Some children had not been calmed by being held or may have even resisted it. Some other children I see develop quite typically. They smile, giggle, rejoice at being held, coo and babble, and ultimately start to use a few words with communicative intent. The parents of this latter and rather rare subset, then watch in dismay as their child withdraws, often losing both functional communication and interest in other children.

The timing of this developmental back-slide most often occurs at around 18 months of age. This regression happens to coincide with the recommended timing of the provision of the Measles-Mumps-Rubella (MMR) vaccine. This temporal chronology is important as it has lead, in part, to a belief that the vaccine itself is responsible for the development of Autism. What these parents must experience at this time, I can only imagine, is a horrible combination of confusion and grief. They have had their hopes encouraged and reinforced only to have them vanquished. And it is human nature, under such circumstances, to look for a direct cause. It makes perfect sense that parents would, given the chronicity of events in some cases, suspect the MMR vaccine as the cause of their child’s regression.

During my occasional community talks on Autism, I often am asked about the alleged connection between vaccines and Autism. The coincidental temporal relationship between the provision of the MMR vaccine and this developmental decay leads to what Chabris and Simons in The Invisible Gorilla refer to as the Illusion of Cause. Chabris and Simons discuss how “chronologies or mere sequences of happenings” lead to the inference “that earlier events must have caused the later ones.” (2010, p. 165). By default, as a result of evolution, our brains automatically infer causal explanations based on temporal associations (Chabris & Simons, 2010).

At nearly every talk I give, there is someone in the audience who is convinced that their child (or a relative) is a victim of the MMR vaccine. Their compelling anecdotes are very difficult to refute or discuss. I find that the application of reason, or data, or both, misses the mark and comes off as being cold and insensitive.

For such causal relationships to endure and spread they often need some confirmation of the effect by an “expert.” This is where the story of Dr. Andrew Wakefield comes into play. Wakefield, a GI Surgeon from the UK published a paper in the prestigious UK medical journal, The Lancet, alleging a relationship between the MMR vaccine and the development of Autism. His “expert” opinion offered legitimacy to already brewing suspicions backed by the perceived correlates of increases in both vaccination and Autism rates, as well as the apparent chronology between the timing of the vaccines and the onset of Autism. Wakefield provided credibility and sufficient plausibility: and as a result, the news of the alleged relationship gained traction.

But hold on! There were major flaws with Wakefield’s study that were not initially detected by The Lancet’s peer review panel. First of all, Wakefield was hired and funded by a personal injury attorney who commissioned him to prove that the MMR vaccine had harmed his clients (caused Autism). His study was not designed to test a hypothesis: it was carried out with the specific objective of positively establishing a link between Autism and provision of the MMR vaccine. From the outset the study was a ruse, disguised as science.

Just this year (2010), 12 years after the initial publication of Wakefield’s infamous study, The Lancet retracted it and Dr. Wakefield has been stripped of his privilege to practice medicine in the UK. Problems however, surfaced years ago: as early as 2004, when 10 of 13 co-authors retracted their support of a causal link. In 2005 it was alleged that Wakefield had fabricated data – in fact, some of the afflicted children used to establish the causal link had never actually received the MMR vaccine!

Since the initial publication of this study, hundreds of millions of dollars have been spent investigating the purported relationship between vaccines and Autism. Despite extensive large scale epidemiological studies, there have been no replications of Wakefield’s findings. Children who had not been vaccinated developed Autism at the same rate as those who had received the MMR. There is no relationship between the MMR vaccine and the development of Autism. As a result of Wakefield’s greed, hundreds of millions of dollars have been wasted. Those dollars could have been devoted to more legitimate pursuits, and that is not the worst of it. I will get to the real costs in a bit.

Another aspect of the history of this controversy is associated with the use of thimerosal as a preservative in vaccines. This notion, which has also been debunked, gained plausibility because thimerosal contains mercury, a known neurotoxin. You may ask: “Why on earth would a neurotoxin be used in vaccines?” Researchers have clearly established that thimerosal poses no credible threat to humans at the dosage levels used in vaccines. However, given the perceived threat, Thimerosal is no longer used as a preservative in routine childhood vaccinations. In fact, the last doses using this preservative were produced in 1999 and expired in 2001. Regardless, the prevalence of autism seems to be rising.

It is important to understand that mercury can and does adversely affect neurological development and functioning. However, long term exposure at substantially higher doses than present in thimerosal are necessary for such impact. The mercury in thimerosal is ethyl-mercury, which is not fat-soluble. Unlike the fat-soluble form of methyl-mercury (industrial mercury), ethyl-mercury is flushed from the body very quickly. Methyl-mercury can be readily absorbed into fatty brain tissue and render its damage through protracted contact. Methyl-mercury works its way into the food chain and poses a hazard to us if we eat too much fish (particularly those at the high end of the food chain). In reality, one is at more risk from eating too much seafood (shark and tuna) than from getting an injection of a vaccine preserved with thimerosal. Yet there does not seem to be a movement to implicate seafood as the cause of Autism.

Even though the relationship between vaccines and Autism has been thoroughly debunked, there is a movement afoot, steeped in conspiratorial thinking, that alleges that “Big Pharmacy” and the “Government” are colluding to deceive the people and that elaborately fabricated data is used to cover up a relationship. This belief lives on. How can this be so? Even intelligent and well educated people I know are avoiding important childhood immunizations based on the fear and misinformation spread by these well intentioned people.

In 2003, in the UK, the MMR vaccine rate had fallen to below 79% whereas a 95% rate is necessary to maintain herd immunity. Currently, the vaccine rates are dropping in the US due to the efforts of celebrities like Jenny McCarthy who purports that her son’s Autism was caused by vaccines. McCarthy campaigns fiercely against childhood immunizations spurred on by the likes of Oprah Winfrey. Even folks like John McCain, Joe Lieberman, and Robert F. Kennedy, Jr have spread such misinformation. Continuing to contend that the MMR vaccine is the culprit, Wakefield has moved to the US and has risen to martyr status among the anti-vaccine folk. You need to know that just months before he published his seminal paper, Wakefield received a patent on a Measles Vaccine that he alleges, “cures” Autism. He has much to gain financially, in his attempt to scare people away from the current safe and effective MMR vaccine.

It amazes me that people do not automatically dismiss this alleged vaccine-Autism link. Wakefield’s conflict of interest and discredited research practices alone draw into question anything he has to say. The mountains of epidemiological evidence also favors rejection of a causal relationship between the MMR vaccine and Autism. However, the power of anecdotes and misguided beliefs place millions of children in harm’s way.

Imagine yourself as a parent of a child who cannot get the MMR vaccine because of a serious medical condition (e.g., cancer). Such vulnerable children, of which there are millions worldwide, depend on herd immunity for their very survival. Now imagine that your child is inadvertently exposed to measles by coming into contact with a child who wasn’t vaccinated (because of misguided parental fear). Because your child’s compromised immunity, she develops the measles and gets seriously ill or dies. Such a scenario, although improbable is not impossible. It is more likely today largely due to the diminished herd immunity caused by misinformation. Whooping Cough (Pertussis) is likewise posing serious concerns (and one documented death) in unvaccinated clusters because of the anti-vaccine folk. This myth persists, in part, because of the Illusion of Cause, and the consequences have become deadly. Next week I will delve into this Illusion that sustains this erroneous and dangerous belief system.

Looking Forward – Looking Back

Jul30
2010 1 Comment Written by Gerald Guild

I find myself in an untenable situation. I have plenty to write about but I am finding that the choices I am making right now, in the splendor of summer, give me limited time and energy to write. I’ve decided to take a short hiatus.

Over the last seven months my writing has been spurred on by relentless curiosity about belief systems that are held despite mountains of overwhelming evidence to the contrary. This cognitive conservatism absolutely befuddles me. And I am further driven to understand why ideology carries such overwhelming power over people and how it drives people to attack evidence or science in general. In a similar vain, I struggle with politics. The efforts made by the United States on the world’s stage to me seem to be a desperate attempt to slay the Hydra by means of decapitation. People close to me, that I love and have deep respect for, look at this war and even the environment in vastly different ways than I do.

Looking back, I have learned a great deal about the thinking processes that drive these different world views. Essentially we have what Michael Shermer calls a Belief Engine for a brain. We are hard wired to believe and make copious errors that incline us to believe – even silly things – regardless of evidence. We have successfully evolved in a world for hundreds of thousands of years devoid of statistics and analysis all the while thriving on snap judgments. Evolution itself, as a process, has inhibited our ability to accept its veracity. Stepping away from the belief engine demands a level of analysis that is foreign and often unpalatable. It is hard to be a skeptic yet oh so easy to go with our hard wired intuitive thinking. If you are new to my blog look back at entries that explore erroneous thinking, rational thought, the adaptive unconscious, memory, morality and even religion.

Looking forward I plan on delving further into our enigmatic Belief Engine. I want to further explore the errors of intuition, specifically the illusion of cause, implicit associations, as well as Jonathon Haidt’s work on political affiliation. Later I hope to switch gears and delve into the unique attributes of our planet that makes it hospitable for complex life.

What Plato, Descartes, and Kant Got Wrong: Reason Does not Rule.

Jun04
2010 2 Comments Written by Gerald Guild

For nearly as long as humans have been thinking about thinking, one of the most intriguing issues has been the interplay of reason and emotion. For the greatest thinkers throughout recorded history, reason has reigned supreme. The traditional paradigm has been one of a dichotomy where refined and uniquely human REASON pitches an ongoing battle for control over animalistic and lustful EMOTIONS. It has been argued by the likes of Plato, Descartes, Kant and and even Thomas Jefferson that reason is the means to enlightenment and that emotion is the sure road to human suffering (Lehrer, 2009).

This Platonic dichotomy remains a pillar of Western thought (Lehrer, 2009). Suppressing your urges is a matter of will – recall the mantras “Just say no!” or “Just do it!” My guess is that most people today continue to think of the brain in these terms. Until recently even the cognitive sciences reinforced this notion. Only through very recent advances in the tools used to study the brain (e.g., fMRI) and other ingenious studies (e.g., Damasio’s IGT) has any evidence been generated to place this traditional paradigm in doubt. As it turns out, emotion plays a very crucial role in decision making. Without it, our ability to reason effectively is seriously compromised. I have long believed that feelings and emotions should be under the control of our evolutionary gift – the frontal cortex. Reason, after all, is what sets us apart from the other animals. Instead it is important to understand that we have learned that these forces are NOT foes but essentially collaborative and completely interdependent forces.

The implications of this recent knowledge certainly do not suggest that it is fruitless to employ our reason and critical thinking capabilities as we venture through life. Reason is crucial and it does set us apart from other life forms that lack such fully developed frontal cortices. This part of the outdated concept is correct. However, we are wrong to suppose that emotion with regard to decision making lacks value or that it is a villainous force.

Jonah Lehrer, in his book, How We Decide discusses this very issue and notes that: “The crucial importance of our emotions – the fact that we can’t make decisions without them – contradicts the conventional view of human nature, with its ancient philosophical roots.” He further notes:

“The expansion of the frontal cortex during human evolution did not turn us into purely rational creatures, able to ignore our impulses. In fact, neuroscience now knows that the opposite is true: a significant part of our frontal cortex is involved with emotion. David Hume, the eighteenth-century Scottish philosopher who delighted in heretical ideas, was right when he declared that reason was the “the slave of the passions.”

So how does this work? How do emotion and critical thinking join forces? Neuroscientists now know that the orbitofrontal cortex (OFC) is the brain center where this interplay takes place. Located in the lower frontal cortex (the area just above and behind your eyes), your OFC integrates a multitude of information from various brain regions along with visceral emotions in an attempt to facilitate adaptive decision making. Current neuroimaging evidence suggests that the OFC is involved in monitoring, learning, as well as the memorization of the potency of both reinforcers and punishers. It operates within your adaptive unconscious – analyzing the available options, and communicating its decisions by creating emotions that are supposed to help you make decisions.

Next time you are faced with a decision, and you experience an associated emotion – it is the result of your OFC’s attempt to tell you what to do. Such feelings actually guide most of our decisions.

Most animals lack an OFC and in our primate cousins, this cortical area is much smaller. As a result, these other organisms lack the capacity to use emotions to guide their decisions. Lehrer notes: “From the perspective of the human brain, Homo sapiens is the most emotional animal of all.”

I am struck by the reality that natural selection has hit upon this opaque approach to guide behavior. This just reinforces the notion that evolution is not goal directed. Had evolution been goal directed or had we been intelligently designed don’t you suppose a more direct or more obviously rational process would have been devised? The reality of the OFC even draws into question the notion of free will – which is a topic all its own.

This largely adaptive brain system of course has draw backs and limitations – many of which I have previously discussed (e.g., implicit associations, cognitive conservatism, attribution error, cognitive biases, essentialism, pareidolia). This is true, in part, because these newer and “higher” brain functions are relatively recent evolutionary developments and the kinks have yet to be worked out (Lehrer, 2009). I also believe that perhaps the complexities and diversions of modernity exceed our neural specifications. Perhaps in time, natural selection will take us in a different direction, but none of us will ever see this. Regardless, by learning about how our brains work, we certainly can take an active role in shaping how we think. How do you think?

Global Consequences of Cognitive Biases

Feb05
2010 10 Comments Written by Gerald Guild

My previous posts addressed several common cognitive biases while briefly touching on their subsequent consequences.  In review, the Fundamental Attribution Error leads us to make hasty and often erroneous conclusions about others’ personal attributes based on our superficial observations.  Generally such conclusions are in fact erroneous because we lack a sufficient understanding of the situational or external circumstances associated with the behavior in question. One particularly counterproductive manifestation of this tendency is the prejudice many individuals have regarding the plight of the poor. The commonly held misbelief is that the poor are so, because they are lazy or stupid or otherwise worthy of their circumstance. Further, the Self Serving Bias is manifested as an overvaluation of the degree of internal attribution the more fortunate make regarding their own personal social and economic position. The reality is that our social economic status has more to do with heritage than with personal attributes such as hard work and discipline.

Confirmation Bias, like Spinoza’s Conjecture facilitates the internalization of information that fits our beliefs and leads us to miss, ignore, or dismiss information that challenges deeply held beliefs. We are thus likely to dismiss pertinent and valid information that may move us from deeply held beliefs. And, perhaps most importantly, these tendencies disincline us from taking the additional steps necessary to critically scrutinize intuitively logical information. Thus we filter and screen information in a way that sustains our preconceptions – rarely truly opening our minds to alternative notions.

These biases are evident throughout society but are plain to see in those who hold strong attitudes about issues such as religion and politics.  The overarching implications are that we tend to cherry pick and integrate information in order to stay in our comfortable belief paradigms. For example, some Conservatives are reassured by watching Fox News because the information aired is presorted based on the core political ideology of political conservatism. Its viewers are presented with information that avoids the unpleasantness of having to legitimately deal with divergent perspectives. Similarly, creationists ignore or negate the overwhelming evidence that substantiates the theory of evolution.

It is interesting to me that the positions held by divergent individuals, liberals or conservatives and skeptics or believers are often quite emotionally based and staunchly guarded.  And rarely are “facts” universally regarded as such.  We are even more likely to cling to these attitudes and values and thus be more prone to such errors in times of distress or threat.  It takes careful rational discipline on both sides to constructively debate these issues.

The tendency to firmly hold onto one’s beliefs, be they religious, political, or intellectual, even in the face of compellingly disconfirming evidence, is referred to as “cognitive conservatism” (Herrnstein Smith, 2010).  Between groups or individuals with divergent “belief” systems, the entrenched rarely concede points and even less frequently do they change perspectives. The polar opposites jab and attack looking for the weakest point in the argument of their nemesis.  These generally fruitless exchanges include ad hominem attacks and the copious use of logical fallacies.

This is clearly evident today in debates between Republicans and Democrats as they battle over public policy. The case is the same between skeptics and believers as they pointlessly battle over the existence of God (as if existence was a provable or disprovable fact).  And it is interesting that some individuals and groups selectively employ skepticism only when it serves their particular interests. This is especially evident in those who make desperate attempts to discredit the evidence for evolution while demanding that different standards be employed with regard to the question of God’s existence.

Because it seems that we as humans are hard-wired with a default for intuitive thinking we are particularly susceptible to magical, supernatural, and superstitious thinking. Compound that default with a tendency to make the above discussed cognitive errors and it is no wonder that we have pervasive and intractable political partisanship and deadly religious conflicts. Further ramifications include the widespread use of homeopathic and “alternative” medicine, the anti-vaccine movement, racism, sexism, classism, and as mentioned previously, ideologically driven denial of both evolution and anthropogenic global climate change.

It is fascinating to me that how people think and at what level they think (intuitive versus rational) plays out in such globally destructive ways. How do you think?
