How can you spot them?

People come to your door.

How do I know if they're really trick or treaters or if they're actually people who are trying to purge me?

True crime would obviously be the...

perfect fit into this category.

And this one's interesting because I think there's a good specific evolutionary reason why we're interested in this as humans.

Yeah, so there's a really popular book that came out, I think two years ago, written by Richard Wrangham.

So he's a biological anthropologist.

He spent his whole life studying apes and trying to understand human evolution through apes and our closest ancestors.

And it's called The Goodness Paradox.

And in it, he puts forward this new theory of

why humans are uniquely what he calls proactively aggressive.

So there's two kinds of aggression in the world, right?

So you have reactive aggression, which you can probably imagine what that means.

It means you react aggressively when someone transgresses you.

So

This is how like most animals engage in aggression.

So if you imagine a chimp troop, you have an alpha chimp and you have this hierarchy of chimps below him.

And the alpha chimp goes and he takes the fruit he wants or the mates he wants or whatever he wants.

And if someone tries to take that from him, another chimp tries to take that from him, he's going to react aggressively.
