Some of the questions are duplicate, in terms of both addressing the same characteristic, but leading it in either a positive or negative way.

Presumably this is to fit in the format of just clicking 'rank' or 'skip', for each question (which I think is also ambiguous).

Surely it would have worked better as 'statement -> yes/no[/skip]', cutting down the number of questions by about half (I'd guess) at the same time?
