Well, it’s worth being a little careful here. Saying dismissive things about an outgroup is an effective way to present myself as a higher-status member of the ingroup; that works as well for “us intelligent people” and “those Mensa dweebs” as any other ingroup/outgroup pairing. Which makes it hard to tell whether I’m really signalling intelligence at all.
