People get good at what they want to get good at, except when they're really dumb - and I suspect ~Warmoth~ is a filtering device that (somewhat) peels off the lower edge of the IQ & ambition pool.

Although, people can be really good at one or another thing and really stupid at some others, a fact to which I can solidly attest, research-wise.
