>The thing is, this sort of thing is pretty easy to manage in real life - just don't make assumptions, and ask people about themselves.

Assumptions are useful, which is why we use them. Yeah you should ask people about who they are and what they do, but do you really want to spend 15 minutes talking with a recruiter that you could have spent talking with a programmer? No, so you have to avoid the recruiters (lets you be stuck with them) and the best you can do is work based on your assumptions.

If you don't like it, try to replace the word assumptions with Bayesian weighted probability.
