While the average person overestimates their own intelligence, the average techy dramatically underestimates the intelligence of the average member of the public. The weirdos that latch onto every fake video and silly conspiracy theory are dramatically overrepresented in every online comments thread, but supposed geniuses in the tech/NGO/academic community forget this and assume a broad swath of the public believes in stuff like "Pizza gate" because nuanced thinking is a skill only the enlightened few possess.
