Might be interesting to add MBTI as a personality factor beyond asking for extraverted or introverted.
I know surveys in the past have shown INTJs and INTPs are greatly overrepresented in Star Trek fans online. Would be really interesting to have that along with political orientation, especially as surveys show INTJ types tend to be very politically pragmatic.
Even then, it seems inevitable that one MBTI classification will have, in general*, more in a particular field of intrigue than the others. That doesn't mean people from the other classifications don't like the show. But of everyone who is whatever classification, what episodes within each classification are we drawn to more than the others? Now there's a fun one that's also free R&D.


* I believe the rule is phrased as "Every rule has that exception. Except this one, probably."
