I have a theory that women are less likely to be, I guess the word would be "assertive", than men. That is a stereotype, but sometimes there's truth in stereotypes. I mean I recall studies that women are less likely to ask for raises or are worse at haggling. So if a person is speaking over you and rambling on, perhaps a man is more likely to speak up or butt in at the first opportunity. The quote in the top comment…
That's a descriptive, not necessarily a normative, statement. What's more interesting to me is why women and men act differently. Do you believe the differences could be the result of child rearing, social climate and norms etc?
