The conventional wisdom about a speech, or an ad, is that it can only ever move half a room: fight for one side, connect with the other, and accept that the rest will tune out. A 2024 field experiment shows that split happening in a real election. The identical mayoral campaign, run as a negative ad, raised turnout among men by about eight percentage points and changed nothing for women. Run as a positive ad instead, it swung women's votes and left men where they started. Economists Vincenzo Galasso and Tommaso Nannicini had found the two halves of the room, each one moved by a different half of the message.
For decades, the stress response behind that split was treated as one universal circuit: fight or flight. In 2000, psychologist Shelley Taylor described a different pattern in women. Under threat, women lean more toward protecting their group and pulling it closer, a pattern she named tend and befriend. The mechanism is oxytocin, a hormone that promotes calm and connection under stress. Estrogen strengthens its effect, and androgens blunt it, so the same hormone pulls the average man toward confronting a threat and the average woman toward gathering people close.
The same split shows up in groups, not just individuals. Mark van Vugt and colleagues found that men cooperate more with their own team specifically when it is competing against a rival group, while women's cooperation holds steady either way. Men bond over a shared fight. Women bond by default.
Two levers follow from this, and each one only moves half the room:
- Naming a threat and calling people to fight it together moves men, an effect that fades once the threat is gone
- Naming the team on its own, through care or protection, moves women without needing a threat at all
None of this means the room has to split. A meta-analysis of fear appeal research by Kim Witte and Mike Allen found that a message pairing a real threat with a clear, doable response beat either lever alone, and gender barely predicted who it moved. Naming a danger only pulls one lever. Naming a danger and handing people something to do about it pulls both, in the same room, at the same time.
A speech, or an ad, built to move an entire room does not need to pick a side between fighting for one half and connecting with the other. It needs both in the same breath: a real threat, and something concrete to do about it. That is not a compromise between the two levers. It is the one message neither lever can reach on its own.
