It's waaaay skewed to the left.
It's a really bad test, to be honest. I mean, consider this question:
A significant advantage of a one-party state is that it avoids all the arguments that delay progress in a democratic political system.
Now, this is true, if highly simplistic. However, it's substantially outweighed by the legion other problems a one party state has. So, what does my answer tell them? Many people will click "Disagree" or "Strongly Disagree" on the grounds that they oppose a one party state. Are those people more left wing than me?
Or how about this one?
Multinational companies are unethically exploiting the plant genetic resources of developing countries.
What? Do they mean for pharmaceutical research? Why is that unethical? I don't dismiss the claim out of hand, but frankly, it's a stupidly vague question.
For the record:
Economic Left/Right: -3.75
Social Libertarian/Authoritarian: -2.97
