Is 2m the ideal height? 1.80m? 2.40m? What would we discover is the optimal IQ? Etc. I think Brave New World treats this question pretty well. We'd probably discover that there is no 'optimal' height or IQ and we'd still need the whole span of "Big Dumb Brutes" to hyper-geniuses. The secret is convince everybody the IQ/physique they've been assigned is the 'actual' optimal and they're the lucky ones that everybody else should envy.
