Looking forward

Three articles provide promising ideas for a next generation of research on ingroup biases in intergroup conflict. An older article by Scheepers et al. raises two issues not taken up in recent studies. One issue deals with functions served by ingroup bias. The more recent article by Bohm et al. reviews what the ingroup-bias literature has shown and where it is heading. Their suggestions for three types of interventions that can de-bias intergroup relations are particularly interesting. A third article comes from American politics. Abramowitz and Webster noted a rise in negative partisanship, which they claim has been responsible for polarization in the American electorate. Justice is a fertile area for research. Welch has recently raised the provocative issue of a universal definition of justice. A rich research literature has developed on boundary roles since 1967.
