René Mõttus talks to Bill Revelle and Bob Hogan who are well respected personality researchers in the field. They argue that the main use of personality research is to predict what real people do in the real world. Yet, much of academic psychology has not taken this seriously, focusing on abstract ideas and models with little real-world relevance. They discuss why useful personality assessment is not about complex statistics or even measuring traits, but simply adding up questions that best predict important outcomes. They also discuss why we should stop believing in Easter Bunnies, how to reassess your work after forty years, and how to build a successful global company. And many other things.
