The most shocking discovery since the “liberal brain”, scientists at Harvard have now confirmed that some humans carry the liberal gene in their DNA.
From the Telegraph
the research suggests that some people have an inherent bias against conservative thinking, that is independent of their education or upbringing.
The effect is caused by a neurotransmitter in the brain called DRD4 which could be stimulated by the novelty value of left of centre opinions, say US researchers.
In people who are naturally outgoing, the feature encourages them to seek out companions with unconventional views as they grow up.
This in turn means they tend to form less conventional political viewpoints as adults, according to the study by the University of California and Harvard.
The research, based on 2,000 Americans, is published in the Journal of Politics.
It found those with a strain of the DRD4 gene seek out “novelty” – such as people and lifestyles which are different to the ones they are used to.
This leads them to have more liberal political opinions, it found.
