I believe you, but again: I haven't experienced anything like this, ever. One of the clearest results we got at Matasano adopting this approach was a drastic reduction in turnover, which is exactly the opposite of what you expect to see if people are scamming their way into jobs they can't do. That's held up (I don't have the before/after comparison, but I do have the industry-wide comparison) over the years afterwards. We hire these people, then we work with them, and they're amazing.
