Another related thing I've encountered is positive/growth vs negative/fixed mindset. Often in discussions someone will make a suggestion and someone else will give a reason why that's not feasible. Everyone might be silent for a moment as no one has a solution off-hand to deal with it and the idea is squashed. One time I made a run-time query optimizer which wasn't all that complicated in any one area but had numerous mechanisms and fall-backs (and a lot of plumbing code). A colleague remarked how he would never have come up with that and listed all the problems which would have needed to be solved along the way to make it all work. I replied that he basically described the roadmap for what I had done step by step. It's sort of like that advice about not giving up on the first "no". Usually a list of reasons why something can't be done rarely contains any actual impossible ones and in many cases can be transformed into a list of things that can.
