The idea of preferences as vectors seems like it has some fun consequences.

- HIPSTERS: If you really like something, but don't want others to crowd your interests, you will pretend to be nonchalant about it.

- AUTHENTICITY: A person's interests in a topic can be vetted as "authentic" if they are influenced by others whose average of personality vectors matches the person's.

- SOCIOPATHS: You can make in-roads with a group of interest by transforming your PV; see AUTHENTICITY.

- SKEW: You can influence others more by projecting a _very_ high value for a specific topic. If you love a particular form of music to an absurd degree, you're more likely to convert others.

I don't have any non-anecdotal evidence of any of these phenomena. Rather, these are some reasonable if not amusing deductions from the author's model.
