Do you need to go out of your way to employ a Spanish speaker as a permanent employee, on the off chance of a "black swan" idea, rather than o a one of consult with a consultant?

wrt your link: "It is important to note, however, that correlation does not demonstrate causality, which would be challenging to demonstrate". I think a more interesting metric would be diversity relative to the local norm.

I add that the only thing that I've seen bringing something to the table, aside from any individual variable is economic class.

I really enjoy when we hire people that didn't had the opportunity to attend to university, but to FP (~ community colleges in the US), guide their training and so on. We did this with three guys in my office and I'd say that was one of the best ideas my boss had.

But now HR is not willing to allow this anymore. Somehow hiring poor people and investing in them is not trendy, but hiring women and minorities is.
