what is some statistical (not anecdotal) evidence of women feeling attraction to "beta" or mediocre (as in inoffensive, low dominance, 5'8 height etc) men as opposed to just being with them for material benefits

why should i distrust the argument radfems make when they claim that they see most men as obsolete and only good for shitting out taxpayer money to fund their lifestyles if they can't peacock with looks or dominate other men? why shouldn't i think that moms who tell their sons to "be nice to girls" are hypocrites who have already let guys who did the opposite rail them?

i would like all top level comments to include scientific citations instead of speculation.
