There are very smart people on 4chan. A well known example:

> Fans were arguing online about the best order to watch the episodes, and the 4chan poster wondered: If viewers wanted to see the series in every possible order, what is the shortest list of episodes they’d have to watch? [...] In less than an hour, an anonymous person offered an answer — not a complete solution, but a lower bound on the number of episodes required. [...] The proof slipped under the radar of the mathematics community for seven years — apparently only one professional mathematician spotted it at the time, and he didn’t check it carefully. [...] Then Robin Houston, a mathematician at the data visualization firm Kiln, and Jay Pantone of Marquette University in Milwaukee independently verified the work of the anonymous 4chan poster [1].

This example tells us a few things. One is that 4chan has users who can come up with new complicated mathematical proofs in a matter of hours. Two - that there are professional mathematicians who read 4chan and can spot those proofs.

Also anecdotally, but on two separate occasions I accidentally discovered that a "smart and well-adjusted" person I know lurks on 4chan. In one such instance the response was similar to "reddit is where dumb people try to act smart, while 4chan is where smart people try to act dumb". I think there is at least some truth in that.
