Stupidity is about lacking intellectual capacity (not necessary the same as IQ, also things like not being interested in thinking, or lacking necessary facts about a subject can give you a lack of capacity.)

Both stating wrong facts and having ridiculous values is correlated with being stupid. So I do not really see how the Fact-value distinction can be used here, stupid people fail at both. (https://en.wikipedia.org/wiki/Fact-value_distinction)
