A lot of the political compass questions tend to favor a liberal response and others tend to favor a conservative response.
Which questions do you think the vast majority would have given a liberal answer and ditto for conservative?
I'd say:
Questions eliciting a liberal response:
It's natural for children to keep some secrets from their parents. (Yes)
Because corporations cannot be trusted to voluntarily protect the environment, they require regulation. (Yes)
Questions eliciting a conservative response:
Land shouldn't be a commodity to be bought and sold. (No)
There are no savage and civilised peoples; there are only different cultures. (No)
Its not only how the questions are phrased, but what questions are asked the impact the bottom line results.
