The Search for Our Inner Lie Detectors
- mtrimpe 13y agoThe book 'The Truth about Trust' [1] explores the latest research around the entire issue of trust, of which lie detection is just a small part, in great and wonderfully readable detail. The TL;DR from there concerning lie detection are a) that it's a classic example of an arms race b) we indeed have subconscious machinery for lie detection yet it needs rich media to function (i.e. voice/text alone does not suffice) c) the only detected signal of untrustworthyness is crossing your arms, leaning back, touching your face and fiddling with your hands (i.e. pretty easy to avoid) d) knowing who to trust is an innate ability of humans starting even in toddlers and plays at many more levels than just 'lying or speaking the truth' [1] http://www.amazon.com/The-Truth-About-Trust-Determines/dp/1594631239 http://www.amazon.com/The-Truth-About-Trust-Determines/dp/15...
- jey 13y agoHow often do results like this turn out to be reliably reproducible? IIRC, much of the "priming effect" literature isn't reproducible. If you're wondering how that could be true: there are systematic biases in scientific publishing that lead to extraordinary claims being preferred for publication, even without the requisite extraordinary evidence.
