How quickly would humans evolve if we prevented anyone with below average height and intelligence from reproducing?

    This question is wrong. Firstly kids inherit intelligence from mothers, that means vast majority of women will have to be chosen regardless height or looks. Otherwise there won’t be enough to reproduce. 

    Secondly height is irrelevant, we should breed based on high eg, ig and health criteria. Those 10 people who do have all three criteria, are not enough to evolve whole planet.

    We could find out by asking Y/A participants to refrain from having children.

    That would at best eliminate some alleles from the population resulting in reduced geneyic diversity. This is devolution.

      This answer is, unsurprisingly, pigshit.

    "Quickly" is a stupid way to attempt to measure evolution. There is no goal we're working towards, so there is no speed at which we move down this imaginary path. Your question is meaningless.

    Neither of those traits are 100% heritable - so probably nothing would happen unless you repeat it with every generation for a few thousand years. But our populations evolve anyway with every generation in our changing environments so your question is kind of muddy.

    no faster than if we don't.

    A eugenics-based breeding program ( LEBENSBORN ) was tried by the (original) Nazis, but failed to produce superior babies. A few years later scientists figured out why, and proved that humans don't come in races

    As soon as the initial below height and intelligence cohort died, so maybe 50 years.

    There's a problem with your methodology.  You haven't set an actual goal.  You've set a moving target.  Eventually the human species becomes extinct.

    Selective breeding is way faster and produces more diverse breeds.

    Hence the dramatic diversity of 400 purposely selected dog breeds, all from the same subspecies of wolves, compared to the similarity of other subspecies of wolves.

    Selective breeding applied to human is called eugenism and is condemned in most cultures

    How about the tall and dumb ones?  Or the short and smart ones?

      What about above average intelligent people who are short because of a chronic medical condition since they were very young, like type 1 diabetes? Don't worry. I don't have human children. And I  too old.
