Many are aware of the Dunning-Krucher effect, meaning that when we start to learn something about a new field, we rapidly feel quite competent and start to act as if we are experts. Then, as we gain experience, it gradually becomes clear that there are many things that we don’t know. Interestingly, the more of an expert we become, the more we are aware of all the things that we don’t know. That’s why so many experts respond to questions that may seem like completely obvious and direct questions to many with a highly unsatisfactory “it depends” style of answer. This is not just the case when we are learning about a new field, but in general with any aspect of life that we don’t know too much about. I think that many of us, including me, would benefit from spending a bit more time considering that we might not know what we need to know in order to have a properly informed opinion. And accepting that it’s perfectly fine to respond to requests about one’s opinion that you don’t have one.
