Thanks for writing.
However, I had an argument with Viliam saying, that people have experience from the past, that searching genetic causes of personality traits, if it resulted into policies, always led to actions, which were ranging from somewhat morally uncomfortable to downright horrible. I could not recollect any single positive example from the past. Has anybody heard of any ?
The first example is closer to specification. We at least know how sterilisation work, we do not need to make a new discovery, so even if the example is not from the past, it is somewhat predictable.
As for my personal reaction to Your both examples, they give me shudders. Right now I am not capable to support this emotion by rational reasoning. I could come up with objections, but would stumble a lot in the process. Probably we can call it aesthetic preference for now. It is possible, other people would shudder too. It is not something uplifting enough to counter the Hitler precedens, for the propaganda purposes outside the Lesswrong culture.

"Hjernevask" a well known (in Norway at least) documentary series that I am sure will be interesting to rationalists here is now available with English subtitles online. Produced by Ole Martin Ihle and Harald Eia a Norwegian documentarian and comedian, it casts a light on both ways in which we know people to be different as well as the culture that is academia in the Nordic country and probably elsewhere as well.
The Series
The link go to the YouTube videos with English subtitles. Because linkrot sucks I'm providing another source for the videos.
Some Commentary
There was very little in the series that I found new and disagreed with some presentations. But this is not surprising given my eccentric interest in humans. (^_^) I found the interviews with the scientists and academics interesting and think that overall the series presents a good overview something well worth watching especially considering some of the debates I've seen taken place here recently. (;_;)
The latter wrote that in a 2010 article on the documentary series that I would also recommend reading. HT to iSteve where it is quoted in full.
