That would mean that we can have fore-knowledge of all sorts of other human characteristics. Political leadership, for instance, That would do away with all those messy elections, and put some old-fashioned common sense back into society.

Children destined to be fascist scientists could be humanely exterminated at birth in the interest of the species - or is that going a bit too far?
Again, the teaching unions offer some sanity. What would we do without those terrible unions?
