Unpaywalled: Diversity training

Unpaywalled: Diversity training

Author: Tom Chivers and Stuart Ritchie August 20, 2025 Duration: 1:05:08

We’re very sorry about the disrupted service over this summer! It’s been hectic with work and a house move and various things. To tide you over, here’s a formerly paywalled episode: our very first one.

…

If you’ve ever done a diversity training session at work, you’ll almost certainly have learned about unconscious bias, microaggressions, stereotype threat, and trigger warnings. Prejudice, racism, and trauma are apparently simmering constantly, just under the surface of our conscious minds.

It turns out that each of these concepts has been subject to a lot of scientific research. It also turns out, perhaps unsurprisingly, that they’re all extremely controversial. In this first paid-subscriber-only episode of The Studies Show, Tom and Stuart look at each of them in turn and try to decide which of them—if any—stand up to scrutiny.

To listen to the full version of this episode and see the show notes, you’ll need to be a paid subscriber to The Studies Show podcast on Substack. See below, or go to www.thestudiesshowpod.com/subscribe, for the options.
