It's science, so it must be true:
The figures revealed that men with higher upper-body strength were less likely to support left-wing policies on the redistribution of wealth.
But men with low upper-body strength were more likely to put their own self-interest aside and support a welfare state.
The researchers found no link between upper-body strength and redistribution opinions among women.
Professor Michael Petersen said: ‘In all three countries, physically strong males consistently pursued the self-interested position on redistribution.
‘However physically weak males were more reluctant to assert their self-interest – just as if disputes over national policies were a matter of direct physical confrontation between individuals.
