If there were more data, it might be interesting to look at the results and see where LWers diverge the most from libertarians (the mainstream group we seem most psychologically similar to), but unfortunately for a lot of the tests, there's too little to bother with (LW n<10). Maybe more people could take it.

Note that you just made an argument for these being terrible bases for public and social policy in a diverse society.

If succesful, you end up with a society that does not have a culture. From this viewpoint I feel for the conservative case. It is very, very weird to try to build a society without culture, it is as if it was not meant for human brains. And it would be very good if people could see a clear dif... (read more)
