First off, let’s address the groups of people in question: Many MRAs, pick-up artists, and incels are unsavory people, and many of their views are reprehensible. So there’s that. I don’t think there’ll be much dispute on the Dope about that.
Now, with that out of the way, the biology or psychological theories that they put forth seem to be, for the most part, scientifically sound. From Reddit and elsewhere, their science is as follows (from what I can gather of them):
[ul]
[li]Women are the bottleneck of reproduction, because it takes a woman 9 months to bear a child (and she cannot bear any other children while already pregnant) whereas men can simply disperse their many millions of sperm about with ease. One man can impregnate a thousand women, but a thousand men can’t all impregnate one woman. So from the standpoint of reproduction, women are incredibly valuable while men are incredibly cheap. (Not that a woman’s value lies only in reproduction, but just saying that insofar as this issue is concerned, women hold vastly more value) [/li][li]In addition to men being less valuable in reproduction, men are also stronger and more suited to rough tasks or danger, and hence society has much less qualms about having men die in combat or dangerous occupations. [/li][li]Women are drawn towards men who possess traits such as confidence, strength, height, status within a group, leadership, maturity, wealth, success and responsibility because those are traits that make for a good provider and defender. Furthermore, being with a male of high societal status also confers status upon the woman as well. [/li][li]Conversely, men are drawn towards women who are young, have attributes such as symmetry of face, curves on the body, etc. because those are biological traits that make for suitable reproduction (a woman who is too skinny or fat, for instance, might not do well in pregnancy; ditto for a woman who is over the age of 45.) (Not that men are consciously thinking such things, but rather, subconsciously drawn towards such attributes)[/li][/ul]
There are other beliefs of theirs, but those 4 listed above are generally the gist of it.
Now, from a sheer scientific standpoint (again, ignoring the distastefulness of many of the people propagating the views,) are these 4 claims necessarily…wrong? They seem to be entirely backed up by facts; women do, in fact, usually prefer men who are wealthy, confident, successful and have status; men generally do, go for women who are young and have a curvy figure and pretty face; society does, in fact, consider men to be more “dispensable” than women in many ways and it is undeniably biologically true that women are the “bottleneck of reproduction.”
