>> How do you deal with the bias from your 'more courageous' people?

That's a great question. We had no general solution for that. We tried to survey people, but results were inconclusive, not statistically significant.

I mean that "courageous" people are more likely to take risks and accept new features and thus probably more likely to be attracted to novelty (see: Novelty Effect) and require longer experiments to understand the actual impact.
