This is a bias of concentrating on past events that made it past a milestone or a selection criteria and not considering the rest. One easy example where this is seen are startup stories that we see from biographies from silicon valley founders, podcasts like, etc. There is a huge bias even in terms of the type of content available which are skewed towards success stories. One way to think about this is that, search engines are trying to serve up what we ask it to. Or maybe that when we try to learn something new, our natural tendency is to look at successful cases and try to replicate them or learn what they did. Rather than looking at failed examples and learning what NOT to do. This goes against the grain in how anything is taught in school and in colleges.
