A Scottish research suggests that being nice or being nasty is in your genes – particularly if you’re a woman.
The study of almost 1,000 pairs of identical and non-identical twins, conducted by psychologist Gary Lewis and colleagues at Edinburgh University, has found that genetic factors appeared to affect how likely someone was to do charitable deeds or work hard in their job.
However, the experts also said the environment in which we live still plays a part in how nice we are, meaning we cannot just blame our genes if we’re feeling a bit nasty. Twins make good research subjects because, in the case of identical twins, they have the same genetic make-up. Comparing them to non-identical twins, whose genes vary, allows researchers to look at what impact genetics has in certain situations compared to other factors such as the environment in which they live.
The researchers looked at levels of ‘pro-sociality’ – meaning contributing to the civic duties of society such as carrying out jury service, going beyond the call of duty at work and paying higher taxes to help other people.
The twins were asked to rate on a scale of zero to ten how much obligation they felt in areas such as testifying in a court case, working longer than their normal hours and carrying out charity work. “What we found is that identical twins were much more similar in their responses to these types of questions than were non-identical twins,” the Scotsman quoted Lewis as saying.
