The difference between right and left

Today, I found an interesting presentation delving into a matter, which I touched upon before: the basic differences between the political right and left.

The presentation, given by one Jonathan Haidt, a professor of psychology at the University of Virginia. Based on his research into moral psychology, he claims to have found evidence of 5 moral foundations, which conservatives and liberals value differently:

He concludes that we need both: The sense of realism and stability of the right wing, as well as the compassion and open-mindedness of the left wing. Apparently, it’s a bit like Yin and Yang. I must admit that I like his ideas, even though I find his research bordering the unscientific.
