A panel of body language experts provides real-time opinions on whether people are telling the truth during political debates. Whenever someone is lying, they press a button, and an indicator appears in the corner of the screen. The more indicators, the higher the probability the person is lying.
Help people spot deception.
How it works
A panel of several body language experts provides real-time feedback/opinions on whether people on the screen are lying.
When an expert thinks someone isn't telling the truth, they press a button. A small red indicator appears in the corner of the screen. Because there are multiple experts, there would be multiple indicators. The more that light up, the higher the probability that the person on screen is lying.
The on-screen indicator could be a minimized version of this:
When the speech/debate is over, release a video version that includes expert commentary about each time they thought the speaker lied.
Versatile truthfulness plugin
The panel of body language experts could be plugged into any broadcasted live event where people are addressing the masses.
Hi Darko Savic , I think the idea has some merit but unfortunately it is not that easy to analyze body language in real time to be able to faithfully determine whether someone is lying. The "teltalle indicators" that are commonly mentioned are rejected by most serious experts. First of all, body language is different for every person and thus the reading needs to be adapted to the normal mannerisms and expressivity of each individual. Secondly, the more scientifically-sound signs of deception, such as disconnection of body parts movement, disconnection of speech and body epmhasis and others, are normally difficult to detect in real time and are almost always seen when being able to re-watch and stop a video.
Additionally, most high-level politicians have absolutely no remorse or conscience when lying to get their own objectives, and they practice a lot how to deliver their lines and get training on how to regulate their body language. This makes it very difficult to detect deception.
However, I think that the video you linked gave another interesting possibility: live fact checks. The video talks about Trump's logical fallacies, which were abundant and obvious in his speeches but a lot of people fell for. Having a pannel of objective experts who signal the objective logical fallacies in people's arguments could do a lot of good. However, this kind of fact checks could never be about ideology or opinions, and would have to be limited to false information and logical fallacies. This would maintain the impartiality of the experts and give them credibility. Otherwise the politicized public would only see them as one more player in the political battle, and ignore their opinion.
How could we make sure that this panel does not get politicized and impartial?
