FOMO Has a Biological Basis

The fear of missing out isn't shallow. It taps the same belonging circuitry that once kept our ancestors safe inside the group.

I.
What it is

The short version.

Fear of missing out is the anxiety that others are having rewarding experiences you're absent from. It draws on the deep drive to stay included. Social media makes it constant by broadcasting, in real time, every gathering a teen wasn't part of. Understanding the root helps: it's not vanity, it's the belonging alarm, now wired to a device that never stops broadcasting.
