Are you a bit inclined towards the Left? It's down to the shape of your brain, says a study.
The study has found differences in two key parts of the brain between people who say they are Right wing and those claiming to be Left-wing.
British researchers looked for patterns in the brains of more than 90 people who professed to have a political philosophy, including British Labour MP Stephen Pound and Tory MP Alan Duncan.
Using an MRI scanner, the researchers studied the shape of the anterior cingulated - the grey matter which houses nerve cells and plays an important part in decision-making, empathy and emotion.
They also examined the two-amygdala lobes, which are key to processing emotional reactions. The grey matter was found to be thicker in people who described themselves as liberal or Left wing and thinner in those who said they were conservative or Right wing. Conservatives were also found to have larger right-hand amygdale lobes than their left-leaning counterparts.
