Laughter Used Transactionally

We think laughter is a response to something funny.
A joke. A punchline. A light moment.

But listen closely to real conversations, and laughter shows up in places that are far more important than we realize - and often when nothing is funny at all.

Neuroscientist Sophie Scott CBE reveals what laughter really signals, how it works, and why it quietly shapes our relationships, our hierarchies, and our sense of belonging.

Sophie Scott is a professor at University College London and one of the world’s leading researchers on the science of laughter.
