OK, so
chronarchy linked to the Political Quiz Show, and it was considered too limiting and one-dimensional. The Libertarians link to a two-dimensional quiz that I find way too simplistic.
So then I came across the Political Compass, which is two-dimensional, and fairly comprehensive. It's notable, however, that this two-dimensional system is directionally different from the one the Libertarians use; the Libertarian Party's ideal is at the top of their map, but would be at the lower right of this one.
Economic Left/Right: -6.50
Social Libertarian/Authoritarian: -7.18Or see the graph at their site.
Authoritarian Left
Right Libertarian
OK, so I'm a Liberal. :-)
(By the way, I'll be posting my PSG writeup soon.)
