I've read that it's face width to height ratio (fwhr), the higher the more dominant the male is perceived as. What other physical factors are included in this? Wide shoulders, small waist probably. Big traps? Height? Facial hair?

I think that if you have more and more of these factors lesser become chances of a woman approaching you.

If these things are exaggerated, do they still apply? I think yes, because it all happens on a subconscious, instinctive level.

My fwhr is over 1.9, so quite high. I have broad shoulders (unnaturally big) with a small waist. I'm also 6'1 without shoes, not the tallest but above average. No woman has ever approached me. Yet I have heard many more beta looking dudes being approached.
