Islamists seem to combine the fertility of bunnies with the aggression of wolves.
Agreed on the Liberal Bunnies. Though it is worth noting, r is always adapting. Those who reproduce today in greatest numbers are less conscientious, and less motivated to greatenss, and probably lower in IQ. Today’s Liberal may seem reasonable and intelligent compared to what they will evolve towards - at least until Darwin returns and culls the popualtion.
On Islamists, HBD Chick’s blog linked above has interesting stuff on that. Her work is all based around the subject of inbreeding, and the effects on behavior.
The concept is, if we are cousins in a very inbred clan, you and I will have very similar genetic profiles, since inbreeding involes genes getting standardized in the population, so to speak. (There are strains of lab mice in which individuals can be used almost as clones, because they are so genetically similar from the in-breeding.)
Anyway, even if I die in the process, I can benefit (in a Darwinian sense) from seeing you succeed, because my genes will go forward in you. Over time, this will produce a drive in inbreds to support kin, as a way of passing hteir own genes forward as much as possible. It is bad for things like democracy, because it tends to produce corruption and nepotism in government, like in the middle east.
The Church, by encouraging out-breeding may have caused people to become less kin-oriented, and this may have favored a more democracy/freedom prone strain of human.
Her blog is very technical, but fascinating in the way she looks at the data.
