Like most situations, you learn more about someone from the questions they ask than the answers they give. The creator(s) of that survey have some extremely binary world views.
I'd be very hesitant to make that conclusion. Much more likely is that more nuanced middle-ground questions are a lot more open to individual interpretation than the "extreme" statements, and thus give you a lot less "signal" in what you are trying to measure - even some of these could be seen as widely open to interpretation.
I'm guessing the scale (rather than agree/disagree) is attempting to compensate for this somewhat.
(Caveat: I'm a scientist but not with a background in anything close to Psychology; I've seen but not written these sorts of tests).
