Also, when you are able to detect and hire the best people you can put a heavy pressure on the competition by simultaneously depriving them of talent and attracting more talent yourself. E.g. if the company A that has 8 out of 10 top people in my field made me an offer then the B with 0 such people will have to make a much better offer for me to even consider them. In such a situation the usual "false negative is okay, it cost more to hire a wrong person than to skip a right one" stops working. Skipping a right one will cost a lot in the long run.
