Research into ‘dark personality traits’ has always focused on men. But some experts believe standard testing misses the ways an antisocial personality manifests itself in women
Picture a psychopath. Who do you see in your mind’s eye? Chances are it’s a man. And chances are your answer would be similar if you were asked to picture a narcissist. From Charles Manson and Ted Bundy to Joseph Stalin, Adolf Hitler and Donald Trump, most famous people we consider psychopathic or narcissistic are male. That’s even the case for fiction – think Hannibal Lecter, Patrick Bateman or Norman Bates.
Scientists long assumed that women were simply too wonderful to be significantly psychopathic or narcissistic, and didn’t bother to study the possibility much, according to Ava Green from City St George’s, University of London. But research over the past few decades is increasingly challenging this stereotype, suggesting women can have a dark streak, too. Much like in autism or ADHD, such traits just express themselves slightly differently in women – making them harder to spot with diagnostic tests that were essentially developed for men.

Phosphate, key to food production, is choking waterways, but a new sponge-like material returns it to the soil for crops
It is one of the least appreciated substances on the planet and its misuse is now threatening to unleash environmental mayhem. Phosphorus is a key component of fertilisers that have become vital in providing food for the world. But at the same time, the spread of these phosphorus compounds – known as phosphates – into rivers, lakes and streams is spreading algal blooms that are killing fish stocks and marine life on a huge scale.
It is a striking mismatch that is now being tackled by a project of remarkable simplicity. The company Rookwood Operations, based in Wells, Somerset, has launched a product that enables phosphates to be extracted from problem areas and then reused on farmland.

From yearning for a ‘strong leader’ to being swept up in riots, the portents for our children are not good – and who can blame them for being so disillusioned, asks Marina Hyde. Oscar-nominated Cynthia Erivo has gone stratospheric as Elphaba in Wicked – what next for one of Britain’s brightest stars? And new research shows western medicine’s traditional split between brain and body is far from clear cut – could this new understanding provide a breakthrough for many complex conditions?
