DIY: 3 rules to catch a liar - C C - Jul 14, 2022

EXCERPTS: . . . A few years ago, a research paper came out that examined the various techniques used in “high-value detainee interrogation” — basically, how to interrogate the sort of bad guys you might see in a movie. Based on this research, we can summarize three rules to catch a liar.
Rule #1. Keep them talking. [...] most people will answer your questions. Rarely do we tend to answer friends or family with, “No comment.” While truth-tellers do tend to speak and reveal more, liars are often hesitant or unable to do so because “they cannot draw on real memories, lack the imagination to fabricate a detailed, plausible story, or fear that they will give themselves away.” What the study found is that letting someone talk reveals them as a liar far better than “accusatorial methods”...
[...] Rule #2. Listen to their feelings (or lack thereof). ... Essentially, it asks us to consider how we store memories compared with how we store fictions. One key insight is that when we recollect a true memory, we reference sensory details (how things looked, smelled, etc.), as well as how we felt about a specific event. On the other hand, when we’re rattling off a made-up narrative, we often use “cognitive operations,” which are much more logical and matter-of-fact...
[...] Rule #3. Get them busy. ... Liars must plan what they say, remember to play a role, and suppress the truth.” The idea is that if you want to spot a liar, you need to make their lying harder. To do this, give them other tasks to do as they are telling their story. If their brain is too busy doing other things, they won’t have enough mental resources left over to lie — or, at least, lie convincingly... (MORE - missing details)

Undercover agents trained by state intelligence agencies are evidently able to evade most common methods to detect lying. One high tech answer:

Are they lying about the success rate? Unfortunately webpages aren't prone to raised heart-rate, facial tics, eye movement/pupil dilations etc. Bummer.

There are a number of myths about detecting deception. Fidgeting, looking away, touching your mouth, all of these things are commonly thought to be practices that indicate deception. Jim Clemente, former Supervisory Special Agent for the FBI, explains why that isn't always the case and how people like him can decipher what these indicators really mean.
