Being openminded should mean that we’re more humble in our thinking and more averse to taking strong stances, right?
I’d love to see some psychological research on this but I am pretty sure that there is good reason to believe that the opposite is true.
If we’re incredibly open to being wrong and incredibly eager to correct ourselves, why take humble positions? If we’re good Bayesians, always looking to update our assessment, then why hedge it by casting it as qualified? Someone might at first think you’re hypocritical but open-mindedness is such a precious and laudable value outside of politics that people will often come around to respecting your flexibility.
Clearly there are good reasons to not overstate knowledge, but there also seems to be a good case to be made that one should juice their capacity for inference for all it’s worth,
especially if they’re always open to altering it.
