Understanding Children's Lies

The video explores the development of lying in children, debunking common beliefs that children only lie after entering school, are poor liars, and that early lying indicates character flaws. Studies show that lying is a typical part of development, with children as young as two beginning to lie. Key ingredients for lying include mind-reading and self-control. Detecting children's lies is challenging, even for professionals. A new technology, transdermal optical imaging, can reveal hidden emotions and detect lies with high accuracy. This technology has potential applications in education, healthcare, and beyond.
