Well, we knew it instinctively, but now "the science" proves it:
The study – Testosterone Administration Induces A Red Shift in Democrats – was published on November 14th, 2021 by Professor Paul Zak, the Director of the Center for Neuroeconomics Studies at Claremont Graduate University.
"His research has made a substantial impact in explaining the variation in human social behaviors and has been cited by other scholars over 18,000 times placing in the top 0.3% of all scholars," explains his professional biography.
Zak's latest findings reveal a link between testosterone levels and political preference through analyzing 136 voting-age males throughout the 2012 election season.
"Our results demonstrate that testosterone induces a "red shift" among weakly-affiliated Democrats," summarized the paper.
So liberal men are a bunch of testosterone deprived wussies!
