Many of us are obsessed with true crime documentaries and podcasts, and actively seek out the most gruesome details of horrific murder, torture and kidnapping. It’s all pretty horrible – so why are we drawn to it? Does ‘evil’ really exist – and if so, what does it look like? Are people born evil or do they become it over time? Emma Kennedy is joined by forensic psychiatrist Dr Sohom Das and the UK’s top expert on serial killers, criminologist Professor David Wilson to uncover why we are so obses...

Most of us could list a few physical attributes for our ideal romantic partner – like preferring blondes or men over 6ft tall. But is having a ‘type’ real? If so, how does it develop? Is it biological, or socially constructed? And is the rhetoric of ‘types’ actually dangerous? Emma Kennedy speaks to University of California Davis Psychology Professor Paul W. Eastwick, and Not My Type: Automating Sexual Racism in Online Dating author and University of Michigan Assistant Professor Apryl Williams, ...

Most of us think we’re too smart, stable and strong-willed to join a religious cult, or to cut ourselves off from our families to join a group devoted to a charismatic leader. But clearly somebody’s joining them. So why do people willingly give up their free will and independence to join cults? Do they realise what they’re getting themselves into? And how do they get out? Emma Kennedy is joined by world-leading cult deprogrammer Rick Alan Ross and NXIVM cult survivor Sarah Edmondson to explore t...

From Terminators and Cylons to the War Droids from Star Wars, military robots are staples of science fiction. But they’re already here in the real world too. The US, China and Russia are all investing efforts into military machines – but they won’t be the gun-toting humanoids we see onscreen. Would taking human fighters off the battlefield increase the peace? Or should we be gravely concerned about this new era of international war? Today on Why?, Emma Kennedy speaks to Kelsey Atherton, an award...

Most of us would like to live for as long as possible, given we’re in good health. But the definition of a long life is changing, and the rapid advancement of anti-ageing technologies could transform the idea of immortality from fantasy to reality. So the question isn’t so much can we live forever, but should we?

Humanity has always been fascinated by the prospect of living on another planet – and our nearest neighbour is the prime candidate. Could we create livable space on Mars? What would we take with us? How would our lives be different? And how would human society change? As climate change and war make the question more urgent, we ask: Could humans really live on Mars? Anna Machin talks to Why? ’s first husband-wife duo, A City on Mars authors Kelly and Zach Weinersmith , about life for the first Ma...

With the news full of war, terror and natural disasters, it’s increasingly looking like the so-called Doomsday Preppers were on to something after all. But most of us still don’t have a clue what – or how – we’d do in a disaster scenario. So when catastrophe does strike, is there a science behind who is more likely to cope? And what can we do to increase our chances? Luke Turner talks to Dr Sarita Robinson, Associate Dean at the University of Central Lancashire and an expert in survival psycholo...

Everything goes extinct eventually. When will it be our turn? And will humans disappear because of shifting tectonic plates, catastrophic natural disasters, the earth being engulfed by the sun… or our own ruinous activities? Basically, how long have we got? Dr. Henry Gee , senior editor at Nature and author of A Very Short History of Life on Earth , tells Olly Mann that it isn’t so much a question of if we will go extinct, but when and why . • “My feeling is that humans will become extinct withi...

You can trust what’s in front of your eyes, right? Turns out… not really. Everything we see is processed through a filter of our prior expectations. Our brains fill the gaps in the data they receive to create a “reality” that we can understand. If everything we see and hear is just a construct, are we all living in our own hallucinations? Anil Seth, Professor of Cognitive and Computational Neuroscience at the University of Sussex and author of Being You: A New Science of Consciousness , explains...

If you could take a pill that would make you fall deeply in love with someone, would you do it? And if you could give someone a pill that would make them love you… would that be right? Therapists have been giving couples psychedelic drugs for over 50 years to help build emotional bridges – but can a mere chemical create something as complex as love, from nothing? Dr. Brian D.Earp tells Luke Turner how therapists could use serotonin-inducing drugs to reroute neural pathways, and why a chemically-...

Our brains process over 35,000 conscious decisions every day – and let’s face it, they can’t all be good choices. So why do we make bad decisions? Which part of our brain is in control when we decide what to do? How do we decide what’s risky but worth a try? How do we process all this vast information? And why do different people make wildly different choices when faced with the same situations? Professor Moran Cerf takes Luke Turner through the neuroscience of decision-making and the hidden mec...

Dads will often say that fatherhood changes you – but did you realise those changes happen at a physical, biological level as well as in fathers’ perspectives and values? We often assume that biologically mens’ bodies are unaffected by the arrival of a child. But huge hormonal changes take place at the point of the child’s birth, and research shows that when fathers interact with their children incredible neural activations take place. How do these changes prepare children for the world? And wha...

Multiverse theory inspired movie blockbusters like Marvel’s Dr Strange and Everything Everywhere All At Once – but the “Many Worlds” theory of multiple realities isn’t just science fiction. If the science is right, could there be another version of me out there somewhere? The Cosmological Inflating Multiverse, for instance, says that ours is but one universe among billions and no scenario, no matter how bizarre, can be ruled out. Can we prove that the Multiverse is science fact? Theoretical Phys...
