Startups do this all the time by hiring mostly asian and white men instead of trying to match population levels. We can't say for sure if that strategy helped or hurt them, but I haven't seen any investor trying to force startups to diversify their workforce.
Sorry, but the left wing is not "science based" at all when it comes to the social sciences - their attitude to social issues is very much religious in nature (see any mention of "socialism" and "wealth taxes" as perhaps the clearest and least controversial example) and "the antithesis of the enlightenment". Both sides are playing this game.
That's quite wrong. Even as we speak, hundreds of millions of people are being lifted out of poverty, thanks in no small part to the gradual adoption of saner policies based in the social sciences. That's not "ideology", it's real results.
But I concede that in other instances better policies based on social sciences are helping us tremendously.
