I think this is a case of "flamboyant headline; reasonable article". He doesn't really argue in the article that people are stupid. It is implied by the headline, but that is clearly just an attempt to get pageviews. The actual content of the article is quite reasonable, and true. While it would be even more reasonable for him to include a paragraph about how other people probably feel the same way about us with things like "social skills" or what have you, that would be off topic, and overly pedantic.
