People who are "fused" with a groupa bond even stronger than group identificationwill take extreme actions to protect other group members, but not outsiders, conclude researchers in a new study published in Psychological Science, a journal of the Association for Psychological Science. This intense bond to a group may help explain the actions of suicide bombers.
Psychological scientist William B. Swann, Jr., of the University of Texas, came up with the concept of identity fusion when talking with a graduate student and a Spanish colleague about terrorism. "We started talking about terrorists and what can cause somebody to engage in terrorism. We all came up with the same idea: That there is something really unique about terrorists and other extremists that goes beyond simple identification."
He calls this phenomenon identity fusion, and says it has two characteristics that make it different from plain old group identity: a sense that you and the group have a shared core essence, and a feeling of reciprocal strength. "You give the group strength and the group gets strength from you," says Swann. People who are fused with a group, whether it's a country or a military unit, often say they would be willing to fight and die for the group.
To test how fused people behave, Swann and his colleagues asked Spanish volunteers how they saw themselves in relation to Spain. This was done using a pictorial scale in which the person and "Spain" were overlapping circles; those who said their circle was completely inside Spain's were considered fused. Each participant answered some variation on the classic trolley problem (in which a runaway trolley is about to kill some people). In one variation, the dilemma was whether you would jump on the tracks and die to save five Spaniards. People whose identities were fused with Spain were more likely to sacrifice themselves, while others would let their fellow Spaniards die. Additional experiments foun
