I think this generalizes as well. People believe what they're told, even if it's coming from people with a poor history of speaking the truth, whether it be misunderstanding or lies. Further, when they realize they've been lied to, they're often bad at going back and invalidating their cache and fixing assumptions based on that bad data. It's really hard - you are told or assume, you internalize it, build on top of it, and then when you realize that you've built on falsehood it's easy to remove that piece without understanding what load it was bearing in your tower of thought. I've found myself doing this all the time when doing designs - I've had to train myself to go back frequently and retrace the logic I followed, being careful not to fall into the same pitfalls and re-introduce the same flaws -that the tower still holds up to inspection when those components were never introduced.
