There are many circumstances in which it is important to detect deception. Whether people are evaluating a partner's account of their activities involved in police investigations, jury duty, high-level diplomacy or simply deciding who to vote for at an election, sincerity is a major issue. How to tell whether someone is lying by verbal and body language clues is discussed, as well as the use of polygraphs, infrared cameras and computerised systems.

I'm a great advocate of false accusations and confessions.

At around 37:00, the guy misses a key point. He says that thermal imaging was around 64% accurate at detecting lies and yet the people by themselves were around 72% accurate. So the conclusion he comes to? The thermal imaging added nothing to the detection rate. That is a false assumption, since that 64% detection rate may very well be detecting the lies missed by the people. Rates by themselves can't be compared, since different information may capture data once missed, and thus it is the convergence of information that leads to a more accurate prediction rate. The better solution would be to use both. The people first make their judgement blindly, then they review the thermal imaging. If both methods detect a lie, then they have a very high chance of lying. If the person detects lying but the imaging does not, go with the persons instinct. Lastly, if the thermal imaging detects something but the person does not, give followup questions. He did mention the latter, however, the convergence of information is missed.

A lot of people really dig big bums and some want to have a big bum,so just be honest. Then people will know that they can come to you and know you are going be straight up.Which is what every body really needs and wants from people.

Surely this talk contains useful material; sadly the delivery lulled me to sleep before I could find out.

Thanks, I now know how to be a lie detector. If only I could be a screwdriver now.

Why be a screwdriver when you can make one?

The worst bores tell the truth. You say"How are you?" The implication that you care is itself a lie, and you HOPE the questioned party lies in response: "Fine, thanks." God forbid they detail the truth of how they are.

An Australian-Indonesian female was convicted recently in Indonesia of poisoning her female friend with arsenic. President Duterte of Philippines says he has confidence in the Indonesian judicial system but I avoid this country. Duterte appears to have abandoned alleged drug smuggler Mary Jane Veloso to the Indonesian judicial authorities where she faces death.
