Btw on Sinflix's test I got:

Left: 1.26, Libertarian: 5.34

Compared to my score on the test I posted:

Economic Left/Right: -3.38
Social Libertarian/Authoritarian: -5.33

Which puts me in the same quadrant in either test but appear to be twice as much to the left on the one I posted. Does that mean the test I posted has a left bias? maybe, but it doesn't really matter. No one is gonna say, oh I didn't know I was a leftie, I guess I better get behind socialism and gay marriage now.
