Die Wahrheit über die Lüge 2019 Directed by Birgit Tanner
Everyone lies, even several times a day. Although this is considered immoral, it seems to be an ancient natural habit. Animals also tell lies for their own benefit. And not every lie is to be condemned. Some are considered a lubricant for daily coexistence. Scientists are trying to track down liars with lie detectors and thermal imaging cameras.
