How much do our genes determine about our lives, and could they influence traits like risk-taking, antisocial behaviour or even violence? In a recent podcast, Ian Sample speaks with Kathryn Paige Harden, a behavioural geneticist and professor of psychology at the University of Texas at Austin, who studies how genetic factors shape human behaviour.
Exploring the interplay of nature and nurture
Harden, author of the book Original Sin, explores how nature and nurture combine to influence our likelihood of committing crimes. She delves into whether the 'cause' of our actions matters for how we think about culpability. The discussion challenges the notion that genetics determine destiny, instead highlighting the complex interplay between inherited traits and environmental factors.
Implications for criminal justice
The conversation raises profound questions about responsibility and punishment. If genetic predispositions can increase the risk of antisocial behaviour, how should society respond? Harden argues that understanding genetic influences does not excuse criminal acts but can inform more effective interventions and a more nuanced view of human behaviour.
Listeners are directed to the full podcast for a deeper exploration of these topics. The episode is part of the Science Weekly series, and Harden's book Original Sin is available for order through the Guardian bookshop.
