"The interviews also revealed something that is important," Holmes said. "When we asked students how these roles get assigned, everyone said, 'I don't know, it just kind of happens.' So they're not really having explicit conversations about whose turn is it. It's just all very implicit, and everyone's trying to be casual." "I think this shows that no one wants to be the boss and tell people what to do," Holmes said. "And that leads to this sort of chaos and lack of authority. That's where we think these gender dynamics and implicit biases and assumptions kind of play out," she added.
