It's interesting to realize that if two groups have the same mean but different variability, the higher-variability group will have more outliers, on both the high end and the low end.
The danger is a kind of genetic fatalism, assuming that what we should do is just to be determined by our genes and how our bodies work. For example, it's possible for a man to produce many children by impregnating lots of women concurrently. I get the feeling that some men decide that the way that a person wins life is that they reproduce as much of their genetic material as possible, so they try to win. It seems like this kind of justification is used to excuse a wide variety of bad behavior: cheating, rape, women as chattel, etc.
It's debatable whether the argument made by the article is actually a real thing, and how much it contributes to the inequality we see in the world. I think social effects have a bigger influence.
But even if we took the argument as fact, it doesn't mean that we have to accept every naive consequence. We don't need to say "Of course the vast majority of CEOs, world leaders, and very wealthy people are male, because the most intelligent people are almost all male". We can choose to have a better society than that.
