Okay.

Final question.

What's the next thing you're working on?

Well, the big thing is this book on collective brains.

So I'm gradually working through that.

One of the ideas that I really am excited about in this book is that we evolve to think in collectives.

There's this assumption that psychologists have had that understand human decision-making and how our minds solve problems is that we should put people by themselves in experiments and see how they do.

But real human societies, hunter-gatherers, they actually work in groups.

And when we want to solve a problem, the first thing we want to do is check with our friends or ask other expert members of the community.

So it's the idea that we think collectively and solve problems collectively in a kind of naturally distributed brain.

And Hugo Mercier and Dan Sperber, for example, have argued and shown with various lines of evidence that many of the sort of

irrational biases we have mitigate or disappear entirely when we solve problems as groups.

So it's almost like we evolved to have that positive interaction and correct each other's errors.

All right.

Great to be with you.
