Cash Keahey works with new and emerging leaders and is often asked what personality types make the best leaders? It’s a difficult question at best and he didn’t have the data to provide a solid answer. So, he took his interest in politics and studied successful presidents based on the assessments of 120 presidential historian-experts and accompanying analyses and authored Eight Leader Types in the White House: Discover and Leverage Your Oval Office Leadership Style. Cash used the Myers-Briggs/Jungian personality theory to develop his leadership types. We all demonstrate these styles depending on our view of the world and we evolve. He suggests we find our leadership type and jump to that presidential chapter in the book to learn more about our strengths and blind spots.
