> The original supposition was that it would be implausible for scientists at large to have an adverse reaction to results that defied their current worldview.
Indeed that is highly implausible. I daresay that anyone stating otherwise fundamentally lacks an understanding of the sort of people that are attracted to and work in the sciences. Paradigm shifts are a form of progress and progress is the raison d'etre.
Note that one or two outliers do not contradict a larger trend. Also that the examples given so far, in addition to being highly unusual, follow from social phenomena downstream of the new results rather than being a direct personal reaction to them.
That said, as noted by others that isn't what's going on in the book being discussed. So the plausibility of that plot point needs to be judged on its own merit as an entirely separate sort of thing.
> Note that one or two outliers do not contradict a larger trend.
The listed cases are not outliers in the scientific community. The individuals were outliers, but the scientific community, in a mode of behaviour that was not outlier-ish, shunned them. This tendency of scientists is well-established: https://en.wikipedia.org/wiki/Planck%27s_principle
At the end of the day, humans are largely egotistical, self-centred creatures, and scientists are no exception. When you say that scientists believe that progress is their raison d'etre, you may not be incorrect, but their belief in progress is grounded in a self-centred way. Perhaps the ideal is "progress for humanity", but the reality is more like "progress for my career" or "progress for my worldview", in which case results challenging everything you hold as a foundation are a threat to you, being regressive rather than progressive in matters important to one's ego. People really, really don't like being told they're wrong. Even scientists.
