Friendships make us happy, keep us healthy, and can even facilitate our reproductive fitness. But most friendships are not forever—even when we want them to be. How do people maintain valued friendships? I propose that “friendship jealousy” arises when people perceive others as posing threats to valued friendships, and that this response can function to prevent friendship loss and friend defection. In preliminary experiments, I tested predictions derived from this functional view. As predicted, I found, first, that friendship jealousy is calibrated to friend value.
