The point about one being an Einstein is curious. People like to make an anti-abortion case by saying that some situations when we are most tempted to perform an abortion are ones that have produced prodigies in the past.
That may be true, but is it statistically relevant?
Could we kill off the psychopaths and still have productive and visionary citizens to a meanginful, perhaps nearly optimal degree? I can't technically prove it, but I think so.
