Economic Left/Right: -1.62
Social Libertarian/Authoritarian: -3.49
Obviously the only thing they are measuring by is the way you answered their own questions and then somehow scoring and graphing it, not an entirely accurate way of showing political views. And judging by the questions and the way they were asked, the test and the graph should in no way be viewed as an unbiased, uniform measurement of political views.
In short, it's all relative. The very idea of mapping political views on a graph can be a bit misleading. There is no uniform mathematical measurement for social beliefs, political views or personal thoughts.
