Here's an interesting heuristic: if an action is morally bad, then its inverse is morally good. Does that seem plausible? If blinding a child is bad, then curing their blindness is good, etc. Applied to this situation: if it's morally bad to enhance the intelligence of a child beyond that of their peers, then it should be morally good to diminish the intelligence of a genius child to be more average. If it's bad to e…
No, I don't think that heuristic passes the sniff test. There are lots of situations where the doing the functional opposite of a morally wrong action is also morally wrong. It's wrong for me to take $50 from you and give it to Bob, and still wrong for me to take $50 from Bob and give it to you. It's wrong to kill babies and wrong to force women to create babies. In these cases the moral inverse isn't to do something…
If it's wrong to kill babies, then it's good to resuscitate ones that have died (assuming they're in the same state they would have been: no brain damage, etc.)
If making one average child a genius is bad for the world, then making one genius child average must be good for the world.
If you're a utilitarian, then the heuristic is basically a tautology: If moving from state A to state B decreases utility by X, then moving from state B to state A increases utility by the same amount.
