not attractive per se. the OKcupid reports found that men are willing to message a very wide variety of women, even ones they don't rank highly in appearance, while women tend to rank most men as unattractive and do not interact with them.
put more bluntly, dudes will try to bang 3's but hope for 9's.
Statistically this is proven false. Find the OKCupid research on women rating men (and the other way around) and you'll find that women do indeed rate only the top percentages of men (afaik top 20% or so) as above average. Wheres men rating women is more of a normal distribution.
Presuming that “rate as attractive” and “chase” are the same thing for both genders, equally. There are many differences in dating patterns between genders, not just how they rate each other in attractiveness.
If we really want to dig in here, women and men don’t even “chase” at the same rates.
It's almost as if there is something in a men that makes him not completely delusional and less susceptible to emotional bullshit rationalisation.
Some day we, as a society, will rediscover the truth about women. One should note, that nature at large do not really forget this reality, and there is a lot to learn in observing the female/male behavior in animals.
