Do you know anyone who has extremely intense relationships—one minute totally in love with someone; the next, flying into a rage and calling them the worst person ever? It’s possible that they have borderline personality disorder.
Whatever that is. What is a “personality disorder”, anyway? How is one diagnosed? In this episode of The Studies Show, Tom and Stuart discuss a disorder that gets a lot of attention online, but which seems pretty tricky to define. And it’s somehow both surprising and entirely predictable that Tom relates this disorder back to his favourite topic: the Reverend Thomas Bayes.
The Studies Show is brought to you by Works in Progress magazine. On their Substack newsletter, you can find different styles of articles that aren’t part of the main magazine, like this excellent walkthrough of nuclear power technology called “Nuclear Reactors for Dummies”. You can find that and much more at worksinprogress.news.
