It seems like it would be a separate problem, but in my experience, the two are linked. The person who is interrupting is interrupting because they're highly confident in their own viewpoint. We like to think that confidence must necessarily be correlated with how true our view is, but that isn't the case. There are some people who are equally confident of all of their views, no matter how much or how little evidence they have for those views. It's those people who interrupt, even though they don't have a clue.
