Subjective confidence in a judgment is not a reasoned evaluation of
the probability that this judgment is correct. Confidence is a feeling,
which reflects the coherence of the information and the cognitive ease
of processing it. It is wise to take admissions of uncertainty
seriously, but declarations of high confidence mainly tell you that an
individual has constructed a coherent story in his mind, not necessarily
that the story is true.
-- Daniel Kahneman, Thinking, Fast and Slow
