Liberal Dementia May be Genetic

There is no question in my mind that the irrational contrary views of many stem from behavioral deficiencies.  We've know these people all our lives.  Contrarians simply for the sake of being a contrarian.  No reason behind it.  More of a social disorder.  So, this report does not surprise me in the least.

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.

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.

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.
