The Science of Personality Podcast

In the latest episode of The Science of Personality, Ryne and Blake are joined by  Hogan’s Managing Director of Asia Pacific, Krista Pederson, and Hogan Senior Consultant in the APAC region, Nicole Dickie, to discuss the findings of Hogan’s Global Leadership Effectiveness Study. Anyone who uses Hogan’s personality assessments or listens to this podcast knows that identifying effective leaders is at the core of what we do at Hogan. The study, which compares personality assessment data from over 21,000 executives in Hogan’s global database with survey responses from nearly 10,000 full-time employees across more than 120 markets, revealed some really incredible insights, including a striking disconnect between the characteristics executives display and the qualities employees say define effective leadership. Krista and Nicole were two of the key people to get this study off the ground, and they join us in this episode to discuss the findings now that the results are in.

In the latest episode of The Science of Personality, Ryne and Blake are joined by Dr. Victoria Grady, Associate Professor of Management at George Mason University's Costello College of Business, to talk about change. More specifically, we dive into the psychology behind why people respond to change the way they do. Change affects us all, but how it affects us varies widely. Some find change to be personally disruptive or destructive, while others seem to just roll with the punches. So, what’s going on here? We discuss that and so much more with Victoria in this episode.

In the latest episode of The Science of Personality, Ryne and Blake are joined by world-renowned author and journalist, Jack El-Hai, to discuss the personality of evil, with a specific focus on the personalities of authoritarians and fascists. This was the focus of his best-selling 2013 book, The Nazi and the Psychiatrist, which inspired the 2025 movie, Nuremberg, currently streaming on Netflix, which features not one, but two Academy Award winning actors. In the movie Russell Crowe plays the part of Nazi war criminal Hermann Göring and Rami Malek plays the role of Douglas Kelley, the US Army psychiatrist assigned to evaluate the personalities and mental capacities of high-ranking Nazis leading up to the Nuremberg trials. Again, this was all inspired by Jack’s book which Pulitzer Prize-winning author Gilbert King describes as “a harrowing narrative that brilliantly probes the depths of evil.” So, that begs the question: What is the personality of evil?
