I'm not saying I don't have beliefs, and sometimes feel that those beliefs are right compared to what other people think, but I try to recognize where things may be objective (like slavery) and subjective (like government spending).

The tool you mentioned makes a lot of sense for issues that have a clear preference e.g. slavery or not, but I suspect it would show cracks if we start looking at more subjective issues (which I imagine dominate nowadays).
