The study pretty much says the exact opposite of what these guys seem to be claiming. 🤦♀️
“Male attractiveness to both men and women is related to a triangular body shape: broad chest, narrow hips, high chest-to-waist ratio. Male shop mannequins are not especially muscular — in fact they are quite slight — but they are abnormally tall (about 187 cm) and very broad in the shoulders and narrow in the hips.
Men, but less so women, are attracted by high muscularity. The average size of GI Joe’s biceps more than doubled between 1965 and 1995.”
The author goes on to say that sociobiologists all believe this is related to “youth and fecundity” as well as virility in men, although that’s the opposite of the conclusion that this other study reached and sounds to me like mostly patriarchal clap trap. Plus, Paleolithic women were so physically active and had such low body fat that they only menstruated 4 times per year. I think I’m going to have to write something more about this.
