I agree with you. To me there is a scale of how more likely I will scrutinize an expert outside of their expertise. If we use the example in the article, the understanding of that statistic is not highly advanced, it’s perfectly plausible for an intelligent doctor to learn enough about statistics without becoming an expert, it’s just this doctor did not, other doctors will have a better understanding maybe because statistics is an interesting topic. For example, it wouldn’t surprise me for a medical doctor to understand the physics of how a wing on a plane provides lift, even though he is not an expert in physics. If he were to explain it, I think he could be quite capable. If he started to explain the physics of a black hole, I would be more likely to scrutinize that. There is a degree of how far one is diving outside of their expertise and how far they’re diving into another.
