Intergroup relations represent one of the most difficult and complex knots which we are confronted with in contemporary society. Given that intergroup dynamics permeate all spheres of our daily social lives, it seems vital to systematically investigate how to best predict and explain when, why, and for whom intergroup relations symbolize conflict rather than harmony. This critical review evaluates how the societal context in which individuals live shapes how their personal social-ideological views, their values, norms and beliefs, are associated with their intergroup and related attitudes. Such an approach not only examines psychological/individual and sociological/contextual levels of analysis simultaneously, it also assesses how both work together (i.e., interact) in influencing intergroup relations across various domains of life. In sum, I found that adopting a person × context interaction approach yields interesting and more profound insights in individuals' attitudes towards ethnicity-, gender, and age-based outgroups, their specifisc expressions of ethnic prejudice (e.g., outgroup negativity, outgroup threat, intergroup contact, and trust within and between ethnic-cultural groups), and even their political attitudes, political party support, neighborhood attitudes and moving intentions.
