Do you really follow this? It seems like someone following these rules would rarely be wrong, but that they'd be paralyzed by the cost of making decisions.
From my own experience and observing others, that indeed seems to be the logical conclusion of it, and it's something that I see happen a lot. "Analysis Paralysis" a friend of mines likes to call it. It can be mildly annoying at times, but it seems like something that a lot of people aren't able to help doing. Or at least not without a lot of practice and experience.
Somebody following those rules could easily be wrong. Even smart, logically trained people make errors in logic all the time. That's why they introduce bugs when they try to write code, or errors into mathematical proofs or philosophical systems that sometimes don't get pointed out for years.
