Some well-known phenomena: ceteris paribus, in conversations between men and women, (a) men speak significantly more than women, and (b) men interrupt women significantly more than vice versa. The effects carry over (not surprisingly) to argument between justices of the U.S. Supreme Court, and there they are augmented by another effect, that conservatives interrupt liberals significantly more often than vice versa. (These results from a study now in press for the Virginia Law Review.)
These effects can be seen as instances of a larger phenomenon: a tendency of those who are, or believe themselves to be, more dominant in an interaction to feel free to impose themselves on their partners and a corresponding tendency of those who are, or believe themselves to be, less dominant in an interaction to avoid imposing themselves on their partners.
