The blog Advances in the History of Psychology pointed me toward an Australian Broadcasting Corporation radio show covering the now-famous Robbers Cave experiments conducted by Muzafer Sherif and his colleagues. It includes fascinating audio from the experiments, interviews with adults who were the boys at the camps, interviews with one of the experimenters (OJ Harvey), etc. It raises some significant ethical issues, as well as some methodological issues. Highly recommended if you’re into social psychology.
