Yes, this is so powerful.
One of my favorite moves is to ask a question that I feel has an obvious answer and then say "what am I missing?" Sometimes I am right, other times I am missing something.
Either way I'm modelling:
- that it's okay to ask questions to which the answer seems obvious
- that it is totally fine not to know everything
Mine is "I'm going to ask the stupid obvious question here", then ask the question.
