Everyone's taken a Big Five personality test at some point, but almost nobody knows what the results actually mean, or whether they're stuck with them for life. In this clip, Drew and I break down the single most replicated finding in all of psychology: the Big Five (OCEAN) traits, what each one actually predicts about your health, relationships, and career, and why not one of them is "good" or "bad," with a single exception. Then we get into the question that actually matters: can you change your personality, or are you set like plaster by 30? The old guard said no. The newer research tells a far more interesting story. I also get into how I trained myself out of being an introvert in my twenties, turned into an extrovert, and then quietly slid back once I started going to bed at 9pm like an old man. Turns out your personality is less a fixed verdict and more a range you move around inside of.
