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?
