Or, how often are folk faked out by their own fears of a lie detector?
I was wondering about that but did not want to mention it in case I looked stupid.sTeamTraen wrote: ↑Tue Jan 21, 2020 7:33 pmThis just in from a UK-based senior psychologist friend:

It's a bogus pipeline - they are using the lie detector to get more truthful self-reports (The Wire, S5E1). Of course they cannot widely publicise this, so it looks like they are using pseudoscience.

Well, given that the placebo effect works, even when you know of the existence of the placebo effect, it is not impossible that the same sort of thing goes on here. Allowing people the possibility of believing that lie-detectors/polygraphs work might mean that they are more likely to tell the truth. Or something handwavy like that. I am reminded of the mental processes in play when, in The Princess Bride Vizzini is trying to determine which goblet of wine he believes Westley has poisoned with iocane.cvb wrote: ↑Wed Jan 22, 2020 8:12 amI was wondering about that but did not want to mention it in case I looked stupid.sTeamTraen wrote: ↑Tue Jan 21, 2020 7:33 pmThis just in from a UK-based senior psychologist friend:

It sounds like voice stress analysis which is hardly new, and surely still as bogus as it always was. Language Log has had many posts against it for the last almost 20 years.plodder wrote: ↑Sat Nov 06, 2021 9:51 amA new, exiting lie detector is being used to fire people
