How much do our genes determine about our lives, and could they influence traits like risk-taking, antisocial behaviour or even violence? Ian Sample talks to 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. In her book Original Sin she explores how nature and nurture combine to influence our likelihood of committing crimes, and asks whether the ‘cause’ of our actions matters for how we think about culpability

**Nature or nurture: can genes make us behave ‘badly’? Insights from new podcast featuring Kathryn Paige Harden**
*London, UK* – The enduring debate over whether genetics or environment shape human behaviour has taken a compelling new turn in a recent podcast discussion hosted by Ian Sample of *The Guardian*. The episode, titled *Nature or nurture: can genes make us behave ‘badly’?*, features Kathryn Paige Harden, a leading behavioural geneticist and professor of psychology at the University of Texas at Austin. Harden’s research delves into how genetic factors influence complex human traits, including risk-taking, antisocial behaviour, and violence, challenging simplistic notions of moral judgment and free will.
### Background context
For centuries, scientists and philosophers have debated the relative contributions of “nature” (our genetic inheritance) and “nurture” (our upbringing and environment) in shaping who we are. Recent advances in behavioural genetics and genomics have illuminated the profound role genes play in predisposing individuals to certain behavioural tendencies. Yet, these predispositions are neither deterministic nor isolated from environmental influences.
Kathryn Paige Harden has become a prominent voice in this nuanced field. Through her research and her book *Original Sin*, Harden argues that acknowledging genetic influences on “bad” behaviour does not excuse it but rather can inform more effective responses to antisocial behaviours by integrating genetics with social and environmental contexts.
### Key details of the podcast and research insights
In the *Guardian* podcast, Harden explains how genetic variation contributes significantly to differences in behaviour, including traits commonly labeled as “bad,” such as aggression or risk-taking. Using twin and genome-wide association studies, her work has identified that genetics accounts for a substantial portion of variance in behaviours previously attributed solely to upbringing or social environment.
Crucially, Harden emphasizes that genes do not function in isolation. Instead, genetic predispositions interact with environment-a concept known as gene-environment interplay. For example, someone genetically inclined towards risk-taking may behave differently depending on whether they grow up in a supportive or adverse environment.
The podcast challenges simplistic binaries that frame behaviour as either a product of choice or destiny. Harden advocates for an integrative perspective that recognizes the probabilistic, not deterministic, role of genes.
### Expert perspective and implications
The discussion with Harden provides valuable insight for policymakers, educators, and the justice system. Understanding genetic influences on behaviour can support more tailored interventions, such as early identification of children at risk and personalized prevention strategies.
However, Harden and Sample are cautious to highlight ethical considerations. Misuse of genetic data could lead to stigmatization, discrimination, or fatalistic attitudes. Transparency, education, and careful communication are imperative in applying behavioural genetics in public policy.
### Market and societal implications
The increasing ability to analyze DNA at scale via affordable genomic technologies is opening new markets in health, behavioural analytics, and personalized education or rehabilitation programs. Companies specializing in genetic risk profiling could see growing demand, influencing sectors from insurance to criminal justice.
Meanwhile, society faces complex questions about privacy, consent, and the balance between genetic insight and individual rights. The evolving discourse around nature versus nurture could reshape social attitudes toward responsibility and morality over time.

**In summary**, the *Nature or nurture: can genes make us behave ‘badly’?* podcast featuring Kathryn Paige Harden sheds light on the complex interplay of genetics and environment in shaping human behaviour. By bridging cutting-edge genetics with social science, it contributes to a more informed and humane understanding of behaviours once burdened by moral judgment alone. The conversation invites ongoing reflection on how science can guide equitable policies that respect both our biological diversity and social humanity.
