The Enigma of Reason (Dan Sperber, Hugo Mercier, 2017)
“Ziva Kunda led participants to believe that extroverts are more likely to be successful than introverts.
On a later memory task, these participants found it much easier to recall memories of their own extroverted rather than introverted behavior.
Another group of participants was led to believe that it is introverts who are more likely to be successful than extroverts.
They found it easier to recall memories of introverted rather than extroverted behavior.
Both groups were simply seeking reasons to believe that they had the qualities that would make them successful. (…)
If reason is an instrument of individual cognition aimed at better beliefs and decisions, it should be biased toward information that violates our expectations.
Reason should look for counterarguments to our generalizations, reasons to question our decisions, memories that clash with our current beliefs. (…)
Instead, reasoning systematically works to find reasons for our ideas and against ideas we oppose. It always takes our side.
As a result, it is preferable to speak of a myside bias rather than of a confirmation bias. (…)
The lawyer analogy brings to mind a context in which persuasion is paramount and the myside bias makes obvious sense: when defending a point of view, the myside bias is a good thing.
It is a feature, not a bug. This fits with the prediction of the interactionist approach.
If the function of reasoning, when it produces reasons, is to justify one’s actions or to convince others, then it should have a myside bias.”
