This thread is so annoying because everyone is debating something that was mis-stated. The original post that started this thread does not describe what the actual research study found.
Upper-body strength in men did NOT correlate with right-wing views, it correlated with self-interest.
It reported that men with higher upper-body strength were more likely to support a political view of economic redistribution that was in line with their self-interest.
Of the stronger men, the wealthy were less likely to support redistribution, and the poor were more likely to support redistribution. This is in line with their self-interest.
Of the weaker men, the wealthy were more likely to support redistribution, and the poor less likely to support redistribution. Both views are against their self-interest.
So, in terms of the right-wing, left-wing thing:
Right-wing political views on economic redistribution were held by the wealthy strong, and the poor weaker men.
Left-wing political views were held by the wealthy weaker, and poor stronger men.
