Right, the Outlier Pyramid! It's a fantastic model.
You *probably* actually saw that on GC first (though it isn't mine)... I posted about it in March that year, in my article on dating in America:
What's Wrong with Dating in America (and Much of the West)
Originates from Jesse over at SeductionScience.com. The post he introduces it is titled "Why Very Successful Guys Should Avoid An Exclusive Girlfriend At All Costs."
The whole post is actually quite wonderful and deep. If you like this graphic, and you enjoyed Franco's post on it, definitely give Jesse's a read too. The pyramid itself is really just a paradigm shift for mindsets - once you're thinking this way, it's pretty hard to worry about whether women have it harder or not.
