Yes, but... ...the analysis of one historian is just that. But the analysis of many historians is more likely to be true, and the consensus of the entire field, held for decades, is even more likely. Certainly more likely to be true than a popular conception primarily driven by comic books, Hollywood films, and popularizations written by non-historians. It's also worth looking at the historian's analysis, and questio…
>and the consensus of the entire field, held for decades, is even more likely. Yes, but at one point, the widely held belief was that the earth was the center of the universe, the earth itself was flat, and the sun was a god being pulled through the heavens in a chariot of fire. So, sometimes consensus isn't right either. Just a bunch of people agreeeing because it is the path of least resistance.
I think it’s important to distinguish between the widely held beliefs of a populace as a whole and the widely held beliefs of experts in a field. I’ll leave aside the point that fields have often gotten narrower as they have gotten deeper. But I will point out that Aristarchus of Samos posited a heliocentric model since some time between 300 and 200 BC and Eratosthenes of Cyrene calculated the circumference of the earth to within the order of 1% error at roughly similar times.
A tangent: is it important what the widely held beliefs of members of Aristarchus and Eratosthenes society believed? I’m not sure. Many members of their society didn’t have access to information or skills that would let them come to these more accurate conclusions. And if they did, there’s nothing particularly actionable for them; imagine a farmer: is knowing the earth isn’t the center of the solar system something that could help them more efficiently grow crops? In this sense, the truth doesn’t have any direct value for them whereas there are potential negative social implications for minority beliefs.
But bottom line: it’s not about consensus itself; it’s about consensus evolving as the most likely scenario given the data available. People in a field will generally have access to more information and the tools to integrate that information into hypotheses than the population as a whole. But certainly experts can still get things wrong. I would just tend to expect better from them than the populace as a whole.
