Late to the party, I know, but I love this article on lying. It so changed me from being hurt and judgemental about the lying, to compassionate *most of the time*. It didn't change me into a parent who has a goal of having children who lie, just that it doesn't jerk my chain in the same way.
Deborah Hage asks: "What internal workings of the brain tell children that lying is an acceptable form of speech?" The article is called "Antecedents to Lying and Teaching the Truth"

If you read it, would love to hear what you think of it.
