Watch my interview at the BMW-Guggenheim lab where I helped create "Love Night" in New York City.
I can confirm importance of morality in social development. 20 years ago i did ask M. Friedman about relationship between honesty and freedom. His site Rose did think it is not important, he didn't write about it in His books, but he did tell to Rose: "No Rose, mutual trust is very important!". Paul Zak is on the best way!
Paul J. Zak is a neuroeconomist at Claremont Graduate University in Claremont, CA. His book The Moral Molecule will be published in 2012.
