Summary

Hosts Peter Shamshiri and Michael Brooks dissect Angela Duckworth’s "Grit," tracing its rise from academic obscurity to a dominant education policy trend. They critique Duckworth’s methodology, exposing statistical exaggerations in her West Point and Green Beret studies where grit often performed worse than existing metrics like physical fitness. The episode argues that the concept was overhyped by media and policymakers, leading to flawed implementations like "grit report cards" despite weak predictive power for long-term success.
