I couldn't help to notice the parallels of weak and strong link problems to sexual evolution. Sexual dimorphism had the tendency to, at least in tournament species [1], evolve towards weak-link females which make up the risk-averse and "gatekeeping" (rejecting unfit males) reproductive basis of the population, and strong-link males with much higher variance in phenotype and mating success.
We humans don't have that much sexual dimorphism compared to many other species, but it has been suggested that human males exhibit higher variability, most prominently in cognitive abilities [2], i.e. more males with either high or low IQ. As always, as soon as something is related to human cognition, take it with a grain of salt, as our minds are very malleable. And, as always, there is a lot of controversy attached to that topic.
