Sin nature

Moral depravity and science

Schadenfreude

It’s a question that’s reverberated through the ages – are humans, though imperfect, essentially kind, sensible, good-natured creatures? Or are we, deep down, wired to be bad, blinkered, idle, vain, vengeful and selfish? There are no easy answers, and there’s clearly a lot of variation between individuals, but here we shine some evidence-based light on the matter through 10 dispiriting findings that reveal the darker and less impressive aspects of human nature:

We view minorities and the vulnerable as less than human. One striking example of this blatant dehumanisation came from a brain-scan study that found a small group of students exhibited less neural activity associated with thinking about people when they looked at pictures of the homeless or of drug addicts, as compared with higher-status individuals. Other studies show that people who are opposed to Arab immigration tended to rate Arabs and Muslims as literally less evolved than average. Among other examples, there’s also evidence that young people dehumanise older people; and that men and women alike dehumanise drunk women. What’s more, the inclination to dehumanise starts early – children as young as five view out-group faces (of people from a different city or a different gender to the child) as less human than in-group faces.

We experience Schadenfreude (pleasure at another person’s distress) by the age of four, according to a study from 2013. That sense is heightened if the child perceives that the person deserves the distress. A more recent study found that, by age six, children will pay to watch an antisocial puppet being hit, rather than spending the money on stickers…
