The floor is a limited resource
Conversation works through an informal turn-taking system. A speaker holds the “floor”—the right to continue—while listeners track the point, anticipate where it is going, and wait for a pause that signals they can respond. An interruption cuts across that system. The current speaker must either stop, compete to be heard, or spend effort reclaiming the turn.
That shift matters because attention is scarce. Once listeners follow the interrupter, the original speaker may have to repeat a point, abandon it, or accept that the topic has changed. The interrupter has not just added words; they have altered what the group is attending to.
Why timing can signal status
A person who speaks over someone else implicitly treats their own contribution as urgent enough to override the other person’s turn. If nobody challenges the interruption, that can make the move look legitimate—and make the original speaker seem less entitled to finish. Repeated interruptions can therefore establish a pattern: one person directs the exchange while another adapts to it.
The signal depends on context. People also interrupt to clarify, show excitement, finish a familiar phrase, or prevent a misunderstanding. A quick overlap between close friends may be collaborative; the same behavior in a meeting, especially when consistently aimed at one person, can curb their influence. The power lies not in every overlap, but in who gets to keep speaking and who has to yield.
