Could you spot a liar? Even if the liar would be a child? It turns out that it ’ s harder than we though. And it also turns out that we should be happy when our children start to lie because that mean (in short) that our kid is growing and he ’ s getting smarter. If you want to test yourself and check if you can really tell if a kid is lying, check out Kang Lee ’ s lecture. Kang Lee is Developmental researcher which studied what happens to children when they lie. You can be shocked how hard it is to say if somebody is liar or not, even if the one who ’ s lying is a child. Questions: 1. Did you manage to find out who ’ s lying? If yes, how? 2. Do you think you are a good liar? 3. What do you think of the morality of the lie? Are there situations where lie is better than the truth? Or maybe we should always tell the truth?
