Analyze a few hundred transcripts of dude-on-dude chatter and you’ll usually find a dominant speaker who holds the floor, and a subordinate waiting for his turn. It’s a vertical structure. But with women, the conversation is frequently much more horizontal and malleable; everyone is an equal player. While men tend to view conversation as an arena for establishing hierarchies and expressing individual achievement, women’s goals are typically to support the other speakers and emphasize solidarity. Thus, women progressively build on what one another says.
