There's a tendency to think that we're all very unique in our preferences, but think about it -- the only way you could really know that, is if you were to already have all of data of what many other people's preferences are. Do we really already know? I study food, fragrance, software and other types of product preferences. In the studies I've done, often people's very subjective preferences (or so we assume) turn out to be highly clustered into just one or two clusters of highly similarly-preferenced people. Sometimes when you'd assume there would be total disagreement, there's actually total preference agreement.
