" the trade-off between truth-default and the risk of deception is a great deal for us. What we get in exchange for being vulnerable to an occasional lie is efficient communication and social coordination. The benefits are huge and the costs are trivial in comparison. Sure, we get deceived once in a while. That is just the cost of doing business. "
