People are (occasionally) aware of things like survivorship bias etc., but I think it's not said enough - when talking about how to do things, we should talk not just to people who wildly succeed, but also to people who fail, or who've failed a lot.
It's not *just* to correct for survivorship bias, either. It establishes more realistic expectations, for one. People who needed to correct for errors are more aware of those errors, for another. Sb who does a thing easily may not know *why*.
