Why is honesty important?

Most of us are honest most of the time.

Why is that? Because when we are, we are able to work more effectively together. We are able to exchange ideas, to transfer money, build teams, and create entire companies that save lives and make the world better, all because we are honest. Our honesty allows us to form alliances to better survive the challenges of life. Dishonesty, and the subsequent disinformation, mucks that all up. It provides unnecessary friction and uncertainty that prevents us from making the best choices.
