Cognitive Bias and the Partisan Wars
Posted May 18th, 2010 by Ira Altschiller –You can find online a study guide to Cognitive Biases.
The descriptions of the biases themselves leads one to think of comedy. Seinfeld could have done, (and by indirection often did), storylines illustrating these irrational paths we all follow in trying to arrive at a rational decision.
Here are some of the biases which could be attributed to those engaged in the partisan wars — apply this to whatever affinity group you wish — they will fit like a glove:
Outgroup homogeneity bias
Individuals see members of their own group as being relatively more varied than members of other groups.
False consensus effect
The tendency for people to overestimate the degree to which others agree with them.
Just-world phenomenon
The tendency for people to believe that the world is just and therefore people “get what they deserve.”
Hyperbolic discounting
The tendency for people to have a stronger preference for more immediate payoffs relative to later payoffs, where the tendency increases the closer to the present both payoffs are.
Negativity bias
Phenomenon by which humans pay more attention to and give more weight to negative than positive experiences or other kinds of information.
Illusion of control
The tendency for human beings to believe they can control or at least influence outcomes that they clearly cannot.
Framing
Using an approach or description of the situation or issue that is too narrow. Also framing effect – drawing different conclusions based on how data is presented.
Moral credential effect
The tendency of a track record of non-prejudice to increase subsequent prejudice.
Bias blind spot
The tendency not to compensate for one’s own cognitive biases.
Bandwagon effect
The tendency to do (or believe) things because many other people do (or believe) the same. Related to groupthink and herd behaviour.
Wishful thinking
The formation of beliefs and the making of decisions according to what is pleasing to imagine instead of by appeal to evidence or rationality.
Reactance
The urge to do the opposite of what someone wants you to do out of a need to resist a perceived attempt to constrain your freedom of choice.
Disregard of regression toward the mean
The tendency to expect extreme performance to continue.
Overconfidence effect
Excessive confidence in one’s own answers to questions. For example, for certain types of question, answers that people rate as “99% certain” turn out to be wrong 40% of the time.
Authority bias
The tendency to value an ambiguous stimulus (e.g., an art performance) according to the opinion of someone who is seen as an authority on the topic.
So, we are irrational creatures. Not out of ill intentions, but out of heuristics: the mental shortcuts we use to make decisions. The best we can do is to find the particular errors to which we are most prone and try and compensate.
Social function clicks in though. If you are struggling to be fair and objective and others seem unconcerned, but out of ego are pursuing their irrational goals, you have lost some edge in the argument. But then your own thinking was similarly distorted, so you may be wrong as well and it is ego that drives the argument, on both sides.
This is why the arts deal with ambiguities and not declarations of conceptual truth in trying to express the human condition.
There is no objectivity, in the humanities or even in the sciences, where at one time, it seemed, science was the sole oasis of objectivity.
