I have grown in confidence over 20 years not by building capabilities but realizing that everyone else is guessing just as much as I am. And I'm at least an above-average guesser in my field of "expertise".
Knowing how to ask intelligent questions is the hallmark of a successful bluffer. Out your comrades lack of knowledge by exposing your own as a very clever question
This helped me in quite a few interviews, and I'm only 39yo. Thanks for putting it in a clear, logic and fun way. My brain had guessed the basic mechanism, but hadn't formulated it in words yet.
For that, I humbly concede you the title of my "BS Master".
