From John Gunkler:

Re: Does your physical strength influence your politics? (May 19, 2013): The article states: “…data showed 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.”

That means that the factor which influenced support of distribution was NOT strength but wealth. Strength was held equally high in these two cases (so it cannot explain a change in support), but wealth changed from high to lower. So it’s relative wealth which influences this political opinion – not a surprise to anyone who’s been paying attention.
