Celebrating the Mind Changers

We collect links to Claudia Hammond's radio series, and our related coverage.

Mind Changers is a radio series presented by Claudia Hammond. In each 30-minute episode, Claudia explores a classic psychology experiment and discovers what impact the study had.

As Claudia recently collected together all her radio and podcast offerings in a fantastic new website, we thought we'd take the opportunity to each episode, and point to our own content on the same topics.
