If you're ruthless... blame it on genetics!

Nature News reported selfish dictators may be able to attrubute their behavior partly to genes, according to a study by researchers at Hebrew University in Jerusalem which claims to have found a genetic link to ruthlessness. "The study might help to explain the money-grabbing tendencies of those with a Machiavellian streak- from national dictators down to 'little Hitlers' found in workplaces the world over," the article said.

The University found a link between a gene called AVPR1a and ruthless behavior via an exercise called the 'Dictator Game,' where players are allowed to behave selfishly or selflessly.

It is unknown reported Nature news how the gene influences behavior, but it may mean that the old adage "it is better to give than to receive" isn't true according to Richard Ebstein, a team leader for the research. The reward centres in the brains of those who acted selfishly may derive less pleasure from seemingly altrustic acts, he suggested according to the report.
