To remind System 1 to stay objective, to resist jumping to conclusions, and to enlist the evaluative skills of System 2, Kahneman coined the abbreviation, “WYSIATI,” what you see is all
there is. In other words, do not lean on information based on impressions or intuitions.
Stay focused on the hard data before us. Combat over confidence by basing our beliefs not
on subjective feelings but critical thinking. Increase clear thinking by giving doubt and
ambiguity its day in court.
