What makes you a good person or a bad person? How do you choose between the devil and the angel on your shoul­ders? What forms your moral compass?

Well, it could be how you were raised. Or your faith. Or the values of the society you live in.

But if you ask a neu­ro­sci­en­tist, they’ll likely tell you that morality has an even deeper, more fun­da­mental origin than that. Researchers are finding that moral decision-​​making is a deeply bio­log­ical process, rooted in your brain.

That’s the sub­ject in the latest in our series: “Brain Mat­ters: Reporting from the Front Lines of Neuroscience.”
