In this episode of the Science Weekly podcast, Ian Sample speaks with Kathryn Paige Harden, a behavioural geneticist and professor of psychology at the University of Texas at Austin. Harden studies how genetic factors shape human behaviour, including traits such as risk-taking, antisocial behaviour, and violence.
Genetic Influence on Behaviour
Harden explores the interplay between nature and nurture in determining our likelihood of engaging in criminal acts. Her book, Original Sin, delves into how genetic predispositions combine with environmental factors to influence behaviour. She questions whether the biological 'cause' of our actions should affect how we think about culpability and responsibility.
Implications for Justice
The discussion raises important questions about free will and the legal system. If genes play a role in shaping behaviour, does that change how we assign blame or punishment? Harden argues that understanding genetic influences does not excuse harmful actions but can inform more effective interventions and a fairer justice system.
