This conclusion hits home for me, ringing true with very different sorts of fields. > First and foremost, group dynamics can develop in such a way that reasonable optimism turns into blind optimism and expressing doubts becomes a taboo. When that happens, it is easy for the group to drift towards extreme positions that guarantee the group's failure. The UML standardisation community became ever more invested in UML 2's success: at first, doubting views were dismissed as referencing trivial problems; eventually such views stopped being expressed at all. The community only talked about success, even when there was significant evidence that failure was the most likely outcome [11]. Similarly, QVT was the wrong idea at the wrong time, but people were so desperate for success that they chose to ignore fundamental problems.
