A Nobel Winning Psychologist
From the vantage point of the unified theory, there is much to like and only a little to critique regarding Kahneman's work. He is a brilliant experimentalist (I believe he is the only psychologist who has won a Nobel prize-let me know if you know of another) and his studies led to a whole field of behavioral (psychological?) economics. His work on the two mental systems, System 1 and System 2 and their corollaries in consciousness (experiential and reflective/remembering) is directly congruent with the model of cognition advocated for in the unified theory. (Behavioral Investment Theory provides the theoretical frame for System 1, and the Justification Hypothesis for System 2).
