In the latest episode of The Science of Personality, Ryne and Blake are joined by Melvyn Payne, Commercial Director at Advanced People Strategies, one of Hogan’s fabulous distributors in the UK, to talk about finding the right balance between team engagement and psychological safety. More specifically, we look at the role personality plays through the lens of Hogan data. This is something Melvyn and his team at APS have made a priority recently as they continue to deliver best-in-class team solutions for their vast client portfolio.

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.
