Dr Emmanuel Pothos (City University) will be talking about “The Clash of the (Formal Probability Theory) Titans” in which he will try to convince us that the reason why human judgments and decision-making often fails to conform to classic (Bayesian) probability theory (conjunction fallacy, violations of the sure thing principle etc) is because human judgment is more naturally modelled using quantum probability theory, which has no problem with such apparent lapses of rationality. 27th Feb 2014, 13:00; Meteorology, GU01.
