They flat out DON'T work at all in detecting lies. Well documented as total fraud. Polygraph just means 'many graphs', which is all they produce: many graphs of sensors output not having anything to do with honest or dishonest responses.
It occurs to me that the electoral system might be used in Pres elections to work (very slightly) in that direction. What if a number of associated candidates made a pact that their electors, if elected, would vote for whichever of the pact makers got the most popular votes overall? Like if Sanders and Biden and Harris were in a pact like that of Democrats (named chosen of unlikely future candidates). People could vote for whichever, avoiding split-the-vote tactics. If Sanders won a state, but Harris got more pop votes nationwide, his electors would instead vote for her.
Complicated maybe, but it wouldn't need any constitutional changes, and might make disasters like a Trump win less likely.
Dumb idea?
I'd like there to be a web-wide expectation by everyone that any AI generated text, comment, story or image be clearly marked as being AI. That people would feel incensed and angry when it wasn't labeled so. Rather than wondering whether there were a person with a soul producing the content, or losing faith that real info could be found online.
Well, those Gaza children shouldn't have committed those atrocities.
