Evidence to expect given a designer

I see this a lot, and it's one of my pet peeves. It's not actually necessary to be able to quantify information; rather it's necessary to be able to order information in an "a > b > c ..." order so we can objectively see if information is added, subtracted, or unchanged without necessarily knowing the amounts of information we're comparing. Of course we both know that neither a quantification or ordering will show up.
