Which begs the issue: If a lie detector is accurate only for answers that are stressful, then it sure looks like we need a detector to figure out if an answer is stressful or not.
Or to put it differently, now you have two problems: Lie detection and stressful-answer detection.
Nevertheless, I concede that your beer detection plan is superior.
- johnfactorial 7y agoIndeed it occurred to me when I took my LDTs that the test's basic premise is: our machine detects stress responses, and our questioner assumes repeated stress coincident with the same answer equates to a lie. Stated outright like that, everyone can see the assumption behind the test is obviously, irredeemably flawed. Therefore I too must concede that the beer plan is flawless.
