I am surprised I cannot find anything by Haidt on this blog. Back when I first heard this I looked further and found his web site yourmorals.org. I took some of the tests. I scored high on the two left moral foundations, high one right, and low on the two other right. Care to guess which of the right ones (Loyalty, Authority, Purity) I scored high?
