Could you elaborate on what you mean by we've confirmed dysgenics? Does that mean humans now are actually more disabled than a century ago?

Population genetics shows harmful mutations tend to accumulate much more than beneficial mutations, but not to a degree that reduces reproduction significantly. So the human genome is degenerating over time.
