Overconfidence
“The most significant of the
cognitive biases.” - D. Kahneman
Confidence comes from the quality of
the story that you can tell yourself
It does NOT come from the quality of
the information that story is based on
It is the consistency of the
information that matters for a good
story, not its completeness.
