Controversial hot topics for the next generation.

A different but equally shunned topic is that of mental ethnic differences.
While it is undeniable that there are physical differences between ethnic groups, from the easily observable differences in skin and hair, to genetic diseases such as Tay-Sacks or sickle-cell anemia, it is taboo to suggest there might be such differences in the brain. The famous Asian studiousness, African sense of rhythm, or German punctuality, must be an unwarranted stereotype at best, or a cultural element at worst. Nurture, never ever nature, and don't even try to get funding for a study that might show otherwise, or you'll be branded "racist" and "Nazi". Is this something that should be changed? It's science's job to seek knowledge, but perhaps there are things society is not ready to know?

I know that its very politically incorrect to say so but to me its obvious that intelligence is mostly genetic. Otherwise a well brought up chimp could be a doctor. And I don't doubt that some ethnic groups have more than their share of outliers on the high side.

The idea of eugenics is very much out of favour, but does anyone realize that eugenics is very much in practise, especially in the USA?
The US has I believe the highest rate of incarceration in the world, and the inmates are disproportionally dark-skinned or dumb or violent by nature. If you believe that these traits are even partially genetically determined, then locking these people up for most or all of their lives (sometimes for ridiculously minor offenses) prevents them from breeding and passing on those genes. This is pretty much the definition of eugenics:
Wiki:" It is a social philosophy advocating the improvement of human genetic traits through the promotion of higher reproduction of people with desired traits (positive eugenics), and reduced reproduction of people with less-desired or undesired traits (negative eugenics)."
