My goal is to help you understand what it means when you see a headline like “Scientists find that people on the political right are less open to experience than people on the left.”

TL;DR: For practical purposes, it doesn't mean anything.

You might guess, from the previous episode, that it's just that personality traits don't predict behavior. That's true, but more interesting things are going on: What does "open to experience" mean, actually? How much less open are conservatives?
