From what I understand you typically need a 'base-line' of normality to know when someone has deviated from that. People can get nervous or make mistakes at any point. The best way to set the base-line is to have a general conversation to put them at ease and then ask the more consequential questions. This could lead to longer queues though which would be an unfortunate side effect.
TL;DR
Use the deviation from the base-line to work out if someone is lying.
- veb 11y agoThat's how the polygraphing process works, right? Isn't that generally regarded as useless?
- watsonc73 11y agoIn short yes but the approach I've seen work is less 'science' and more about judgement calls when analysing micro expressions. Without the base-line, it's hard to work out what a normal reaction is and what could potentially be a tell.
- mratzloff 11y agoIncidentally, this is how I interview people. Random BS for 5-10 minutes followed by interview questions. It also works for one on ones with staff to tell a recent funny anecdote about some subject they're interested in to get them to breathe and open up a little.
- watsonc73 11y agoI do the same when interviewing. I came across this technique when looking at a Body Language course hosted by Vanessa Van Edwards. Most of it was superfluous but I thought the parts around 'reading' the truth from non verbal clues was very interesting.
