* hypergamy = thrival

the term 'hypergamy' has been garnering a lot of attention in the manosphere, but it is nothing new.

in short, hypergamy is the tendency for a female to choose her best mate.  literally, she is simply doing the best that she can do to make her life better (which is thrival).  

she seeks:

1. the most fit male to co-produce the best offspring, and
2. the most stable male to best protect the offspring. 

the challenge (for the committed male) is that rarely does one man satisfy both needs.
