The 2017 academic paper: "Applying sexual economics theory to mating contests" from the Journal of Economic Psychology, is MGTOW 101 and I highly recommend reading it.

For the men who are still struggling from the betrayal of your former wife/girlfriend, it helps to realize that cognitive dissonance remains within your brain which is causing you trauma; we know that men are co-operative by nature but we mistakenly project that trait onto women, when women betray us we can't understand why because this is so foreign to our co-operative nature; it's so foreign to our mental construction of the world! It's important to realize that women are not co-operative, they are not like us, they are self-interested, hypergamous, opportunistic entities.

This realization helped me a lot after my former-wife betrayed me with multiple men, I just couldn't fathom how someone could treat another person so poorly, let alone a person that she professed to love. Realizing that she doesn't think like me and that she's not co-operative was a big part of my healing journey. I hope this helps other men here.

SUPPORTING QUOTES FROM THE PAPER:

1) WOMEN AREN'T CO-OPERATIVE

"... women have rarely worked together to build institutions capable of producing surplus wealth. The deficit in women's cooperation has been apparent throughout history and continues to be evident among modern samples ... reviewed evidence of co-operative prosociality among nonhuman primates ... concluded that early cooperation is mainly for purposes of physical combat ..." Page 233

"... women compete by damaging each other's reputations ... they seek out damaging information about rivals, they pass along such information when they get it ..." Page 237

2) MEN ARE CO-OPERATIVE

"As early hominids became better at controlling local resources and thwarting predators ... This increased human tribalism and cooperativeness - and primarily among males." Page 238

" ... before the men can court the women, they need to amass resources by defeating other groups of men, and toward that end, adding another strong and capable man increases the group's chances of success. Yes, that big strong man might steal the heart of the woman you fancy - but on the battlefield, that same big strong man might save your life and enable the group to prevail so as to claim the disputed resources." Page 238

3) WOMEN ARE HYPERGAMOUS

"... she chooses him on the basis of the resources he can provide, that is, on the basis of nonsexual benefits he can furnish to her." Page 231

" Women are generally attracted to high status men, because they seek partners who can give them resources." Page 238
