The problem with selectively breeding humans isn't that it's impossible, it's that it is immoral.
Is it immoral to favor mates who have good heritable traits? If so, why?
Not on a personal level, no. We all have our dating preferences! What's immoral is any government program trying to guide selection at the population level.
As a libertarian, I would never support coercive eugenics. Freedom of mate choice is fundamental. But historically many advocates of eugenics have favored voluntary initiatives based on education, not coercion.
I suspect Colin is (primarily) referring to coercive reproductive policies.
You are correct.
Ask anyone looking for sperm donors if they believe in eugenics.
Not at all. Everyone chooses mates based on particular characteristics. It's only immoral if other people choose who one mates with. Interestingly, I wonder if this is a primary reason for the disgust felt regarding arranged marriages (even with their utility).
Depends who gets to do the selection, if it's individuals freely acting on their personal preferences, or if it's an higher authority imposing certain rules on the population.
People do this all the time without even thinking about it. Of course personal preferences do interfere but certain traits are very universal
No, but that's not really eugenics - preventing others from breeding because you think they have bad heritable traits is immoral.
Agreed. What about when machine learning can pick which embryo to use for in vitro based on genetic markers for desirable traits? (they could do this now if they had DNA data with IQs instead of just edu attainment to train on) Is that "eugenics?"
