Intervention Effect Sizes Put Into Context

In any given school, you’re never more than 6ft away from a poster about “growth mindset”. It’s the massively-popular idea that if you believe that people can change, you’ll put more effort into a task (like studying) and end up doing better at it. On the other hand, if you have a “fixed mindset” and think talent is innate and unchangeable, you won’t put in the effort and you’ll fail to reach your potential.

In this episode, Tom and Stuart talk about how the claims about the power of growth mindset have changed over the years, and explain the convoluted back-and-forth story of recent studies and reviews of the evidence. Do growth mindset interventions help kids get better grades? Is growth mindset even a thing? Take a listen to find out.
