Schwarzenegger? Stallone? There may be something to their conservative political leanings.

A new study by two psychological scientists asserts that a man’s physical strength will affect whether or not he supports the welfare state, according to the Daily Mail.

Starting with the hypothesis that upper-body strength — “a proxy for the ability to physically defend or acquire resources” — would sway a man’s conclusions about redistribution of wealth by the government, the researchers then collected data from the U.S., Argentina and Denmark.

The data revealed that wealthy men with high upper-body strength were less likely to support redistribution, while less wealthy men of the same strength were more likely to support it, the Daily Mail reports.

“Our results demonstrate that physically weak males are more reluctant than physically strong males to assert their self-interest — just as if disputes over national policies were a matter of direct physical confrontation among small numbers of individuals, rather than abstract electoral dynamics among millions,” said Michael Bang Petersen, one of the scientists.

The results of the study were published in the journal Psychological Science.
