Conjunctions do not work with medians that way. From what you quoted, it is entirely possible that the median probability for that claim is 0. You can figure it out from the raw data.

I don't understand. Since existence of God is explicitly included in the question about the existence of supernatural things, everybody should have put P(God) < P(Supernatural), and therefore the median also is lower (since for every entry P(God) there is a higher entry P(Supernatural) by that same person). So the result above should be weak evidence that a significant proportion of the LW'ers fell prey to the conjunction fallacy here, right?

No, I think that a god that does not interfere with the physical universe at all counts as not supernatural by the wording of the question.

My point was that the median of the difference of two data sets is not the difference of the median. (although it is still evidence of a problem)
