The Whole Truth About Lying

Everyone lies. Every day. Several times. This is immoral, but seems to be an ancient natural heritage. The ability develops in childhood.

From the age of five, children understand how cheating works. If a child knows how to lie, it speaks for a well developed brain. Animals also cheat for their advantage. Not every lie is to be condemned. Some are regarded as tools for a healthy social base, others, however, are pronounced with fraudulent intent or out of self-interest. Scientists try to measure the signals of liars. With lie detectors and thermal imaging cameras they are on the trail of liars.
