Cross product YES-NO answer model

I was just thinking, many questionnaires model yes/no answers as one or the other, with some logicians using fuzzy logic to describe situations in between.

I wonder though, if yes and no were regarded as different emotions rather than as just answers, couldn't one just give a percentage for each, for example when filling out a questionnaire?

Has this approach been used?
