Our genes help shape our political views, by the Daily Mail from 2013.

A new study has found that our political attitudes are hard-wired into our DNA, with 56 per cent of each belief influenced by our genes.

Individual experiences, upbringing and other social influences explain the remaining variation in our left or right-wing orientation, according to the study. …

Study co-author Dr. Kevin Smith, a political scientist at the University of Nebraska-Lincoln, told HuffPost Science …

‘I know people get bent out of shape about this. The environment is important, it’s just not everything. …

‘Some observers have the idea that if people just talk about politics long enough, everybody will come to agreement,’ he told HuffPost Science.

‘Our research, as well as that of others in the field, indicates that political differences run deep, are biological, and affect the way the world is perceived and processed.

‘It is pleasant to believe our political foes are merely uninformed but often times (not always) they are well-informed but just have different predispositions.’
