Rationalizing missteps pays off better than acknowledging mistakes - the latter is seen as a weakness
Yet few people cogitate on how to reduce this downside risk
Rationalization and non-admission of supposed "mistakes" is a good thing, as it contributes to intellectual diversity
Else we sort of acknowledge there is one "right" course - and all other courses are "mistakes" that ought to be shunned
It contributes to a certain ideological totalitarianism
By refusing to acknowledge error, but rather making a case for our own ideological distinctiveness, we are guarding ourselves against group-think and moral homogeneity
So it's a fine balance
Within-group variance
Variance across groups
And it helps increase variance in views across groups
But it comes at the cost of reducing variance within a group - where everyone is supposed to be loyal
But by championing the idea of progress and the notion of "objective truth" - it's susceptible to groupthink across groups
It tends to reduce variance across groups
