Thinking, Fast and Slow describes this man's work with Amos Tversky.
This man found that residents of Southern California and the Midwest reported similar levels of general well-being but both groups expected Californians to be happier, an example of what he called the "focusing illusion." This man argued operations such as combining probabilities or segregating different options occurred during the editing phase of decision-making, which is followed by the evaluation phase. This man and an alphabetically-latter collaborator wrote a paper that proved the substitution axiom rarely holds because people give disproportionate weight to (*) certainty. That paper also introduces the reflection effect, the name this man gave to observed risk aversion for gains but risk-seeking for losses. Thinking, Fast and Slow describes this man's work with Amos Tversky. For 10 points, name this co-developer of prospect theory.
