This is exactly the kind of work which will hopefully help us to stop being so tribalistic, and seriously look beyond partisanship.
Moral and Political Psychology
In the last few days we've been exploring a putative evolutionary basis for political groupishness. Tom suggested it was due to group selection, I suggested that it wasn't, but I think that we both agree that there must be some psychological trait which underpins our political choices. Jonathan Haidt is a pscyhologist who explores precisely these issues. In this interesting lecture, he explores five dimensions of morality and how they are differently emphasised in the minds of liberals and conservatives.
