Author and researcher Samuel Barondes does an amazing job in this seminal work on personality and psychology. After much research, analysis, and collaboration, he and his colleagues formulated the OCEAN model for personality traits - Openness, Conscientiousness, Empathy, Agreeableness, Neuroticism. This model is widely used in ways you may not even be aware of. I found it a great addition to my readings on psychology, personality, leadership, and self-development. With useful examples of well known people as well as historical events, Barondes helps the reader to grasp not only their own various traits but also explore how this model can help them understand to better interact with others with a different mixture of traits. While I personally believe “All Models Are Wrong, Some Are Useful” (George Box), this model is incredibly useful with a vast research base and empirical evidence to support its formulation. I’d recommend this book for any Manager, Change Agent, Team Member, or anyone else interested in a useful model to understand themselves a little more.
