"Lie detection is like language; there is a learning window. Telling whoppers to small children seems to be a family tradition in many families"

This quote by Keith Henson is describing the capability to identify lies. He is recommending that, much like language, there is a window of time in which we can learn to find lies. He is also indicating that in numerous family members, it is a tradition to inform lies to little kids. This could be viewed as a method of instructing them to detect lies, as they will certainly have the ability to recognize when someone is not informing the fact. This quote is suggesting that the capability to discover lies is something that can be found out, and that it is important to show youngsters to identify when a person is not being sincere. It is likewise recommending that this is an ability that is passed down via generations, as it is a tradition in many households.
