What Twins Tell Us

Hidden Brain

About this episode

In December 1988, two sets of identical twins became test subjects in a study for which they had never volunteered. It was an experiment that could never be performed in a lab, and had never before been documented. This week, we revisit this fascinating story, told by psychologist Nancy Segal, about the eternal tug between nature and nurture in shaping who we are.
