I'd be curious if women actually did complain more than men do, or if that's a myth, or if women are more likely to express displeasure in ways that are labeled "complaining" (as opposed to "arguing" or "debating")? I know that the plausible-sounding and widely believed claim that women talk more than men do but the effect seems to be either very small or nonexistent.

It'd be interesting to see a study on this using a similar soundbite capturing device to find out if women did actually complain more. Even though there'd be issues with defining "complaining," it could be useful. I'd predict that Hanson is coming up with an explanation for an effect that doesn't really exist.
