The conventional wisdom about science is half-a-century or more out of date. Up to roughly World War II, it was not too wide of the mark to see scientific activity as driven by the curiosity of dedicated individuals who collaborated and competed to tease out a comprehensive understanding of the natural world. No one chose a career in science as a way to wealth, because it wasn’t. By and large, mutual critiquing was based on evidence and logic, and controversies became resolved reasonably soon after the evidence became objectively compelling. Personal unpleasantries did arise, notably in disputes about priority of discovery, but they were between individuals and their close cohorts, not the guardians of a mainstream dogma branding dissenters as denialists, pseudoscientists, or criminals who should be jailed. Of course there was always resistance to new ideas, but it involved ignoring the intellectual challenge rather than seeking to kill the messengers.
