I haven't thought a lot about that, but it's a great question. Maybe: 1. Try to affect a culture of and signal "we're working together / collaborating, not competing with each other." 2.

Expect and tolerate mistakes, simple/"dumb" questions, saying "I don't know", and build support structures for learning collaboratively.
