Works as a parent too. The kid thinks they’re a genius for knowing something the parent/teacher doesn’t, learns a valuable lesson that adults can be wrong, and learns how to find truth. When we conflict, I say, “let’s look that up,” whip out my phone and look for 2-3 reliable sources on whatever the subject is, and read it together. Then I explain why I thought what I thought, which is a valuable lesson in how biases can cloud our judgement, and sometimes I find I’m wrong about something related as well.
I’m usually right, but sometimes I’m wrong, and I think that’s awesome.
