/r/all Ryan Waller, a 22-year-old man who, despite having a bullet in his eye, endured 4 hours of interrogation by cops who thought he was lying—only to receive medical help too late.

I would love to see that actual study if you happen to have a link handy

Tried to ask chatgpt and it came up with the opposite.

Ekman, P., & O'Sullivan, M. (1991). "Who can catch a liar?" This study investigated the accuracy of different groups, including regular people and professionals trained in deception detection, in identifying when someone was lying. The results showed that certain trained groups, like law enforcement personnel, performed better at detecting deception than untrained individuals.

That's because they made it up lmao. From what I remember from social psychology is there is no definitive tell when someone is lying. So you really can't be trained on it. This is generally of course as everyone has caught people in lies before (especially if you know them) and some individuals might have tells; but no, there isn't a definitive way to generally tell if someone is lying.

sigh, I tried googling about it and also came up empty. I really wish people would stop referencing studies without citing them, it should be straight up not allowed. u/Warm_Month_1309 you must redeem your good name by providing a source now 😬

The simple answer is that ChatGPT is not a trusted source of information. From the abstract of the cited study: "Only the Secret Service performed better than chance, and they were significantly more accurate than all of the other groups".

You can read it (and its references to other similar studies for a broader view) here: https://www.researchgate.net/publication/374666089_Who_Can_Catch_a_Liar

It is, however, an older study. A more modern one here: https://pmc.ncbi.nlm.nih.gov/articles/PMC9037296/

Upon review, I may have been overzealous in my claim that law enforcement in general performed "worse"; only a minority of studies actually found that. The consensus seems to be merely that they perform no better. Although this assumes correct training. Someone who has been trained on pseudoscientific principles and who overestimates their own ability to spot non-existent "tells" of a lie would perform worse.
