| Abstract: | Humans exist not only as unique individuals, but also as members of social groups that are formed on the basis of ethnicity, gender, age and so forth. Reflecting this duality are interpersonal and intergroup modes of behaviour, respectively. Thus, humans can act in terms of their personal self and treat others as individuals (interpersonal behaviour); they can also act in terms of group membership and relate to others as members of this or that group (intergroup behaviour). In a mixed marriage, for example, the couple's behaviour toward each other is ‘normally’ interpersonal, but can become intergroup when war breaks out between their respective ethnic groups. Contrary to common sense, factors more minimal than a war are often sufficient to trigger intergroup behaviour. Indeed, seemingly interpersonal encounters are in fact intergroup. How does behaviour shift from interpersonal to intergroup, and with what consequences? To address these questions, I outline a social psychological perspective based on social identity theory and conclude with a discussion on the enigmas of ethnicity. |
