A main form of insight is a hypothesis that one hadn’t previously entertained, but should be assigned a non-negligible prior probability.
Why use “prior probability” here instead of just “probability”?
Because the error (corrected by the insight) is failing to consider the hypothesis at all, rather than incorrectly thinking that it is ruled out by evidence.
