I think we're past that. Setting aside politically hot topics like IQ, Height is genetically determined and makes a huge difference in life outcomes. Now it's all about what we do with that information.
That makes height an easy topic to talk about, but it's still challenging to think through the implications. If you can increase your child's height by 20% and thereby increase their likely income by 25% - is it morally right not to? Does it matter whether others can afford that intervention? Is it morally right not to fund public access to such interventions? Does the answer change if relative height is all that matters?
