One of my favorite historical tidbits is that Arab traders, for centuries, fooled Europeans into thinking cinnamon came from a rare, vicious and fearsome cinnamon bird.
The belief was so prevalent, in fact, that the mythical cinnamon bird shows up in the writings of Herodotus and Aristotle, all the way into medieval European manuscripts where it’s illustrated in all its fierce, cinnamony glory:
Pliny the Elder expressed skepticism of the bird in his writings, rightly assuming that it was a tale invented to keep control on the trade and prices by reducing competition, but the belief was already so widespread that it persisted in many areas into the early 1300’s.

This is a fantastic linguistics paper – the researcher observed the artificiality and social pressure imposed on kids when they're asked to produce language on the spot, so instead had them talk to a rabbit in a room with a tape recorder. He found that when talking organically, without an adult authority figure around, their speech was exponentially more sophisticated, socially fluid, and creative.
As someone in the twitter thread points out, this has obvious implications for situations in which cued language production is used in diagnosis e.g. for autism. I'd add that (while this particular paper's remit is limited to children) it should also make us think about situations where adults are pressured to speak by authority figures: court hearings, police encounters, benefit assessments, asylum interviews, etc. If the presence of power hampers your ability to advocate for yourself, these are all rigged propositions.
Anyway, you can read the whole piece here (taken from a talk on his research, so it's very readable):

e: sorry, I should add the context that this is a language study situated in Hawaii in 1970 so there are also some very significant racial socio-linguistic politics discussed here that might be distressing to read about. I don't want to discount that aspect of the power dynamic studied here either.
