content: this is the view i had too. but remember what happened with the race question. you hear the opinions of supposed experts, don't think too much about it, and repeat the narrative because it SOUNDS plausible. the fact that there is a general consensus view of polygraphs being unreliable -- this could be the result of a simple narrative pilpul just like with race. remember how convincing that argument of "it's a spectrum" was? and look it's just the continuum fallacy think about the premise too. that because the lie detector isn't perfect, or only is right 70 to 85% of the time, that means it cannot be used to gather data or as a heuristic / correlate for truth. this is just a fallacious idea take the truthpill
