As far as I know he's a psychologist with no formal education in philosophy. Why would you rather like to see him as a philosopher? After all, philosophers have a different line of expertise than psychologists, which shows in their education.
The most obvious choice for a real philosopher would be here to discuss Plato's Republic, given that all of the crucial insights that these psychologists are now tarrying with were already almost 2500 years ago predicted by Plato.
