I don't think you got my point at all. My point is that even natural science, which is "hard science" and much easier falsifiable, this also happens. I found the video if you're interested (It's by Be Smart, I was wrong about the channel).

There is also a video about the history of work that is more on topic. If you don't want to watch the video, you can just read the sources in the description.

But talking about anthropologists: here is a quote from David Graeber's book Bullshit Jobs:

Feudal lords, insofar as they worked at all, were fighters—their lives tended to alternate between dramatic feats of arms and near-total idleness and torpor. Peasants and servants obviously were expected to work more steadily. But even so, their work schedule was nothing remotely as regular or disciplined as the current nine-to-five—the typical medieval serf, male or female, probably worked from dawn to dusk for twenty to thirty days out of any year, but just a few hours a day otherwise, and on feast days, not at all. And feast days were not infrequent.

He is an anthropologist who devoted his whole career debunking such claims and published a book together with a historian who does the same. It's called "the dawn of everything" by David Graeber and David Wengrow (2021). You should check it out. I could look up more anthropologists to back my claim but I don't want to spend too much time for people who talk down on me (none of these are block posts, surprised?) and you are yet to come up with all the anthropologists and historians (not economics, they don't count) who support your claim.
