Psychologists have been studying the interplay of social injustice, righteous anger, and group allegiance. It appears that loyalists are not simply apologists for anything and everything the group stands for. In fact, loyalty may be a predictable step toward taking a firm and principled stand.
New York University psychologists Heather Barry and Tom Tyler studied this phenomenon, focusing on students' loyalty to their university. In one study, for example, they used an elaborate procedure to measure the strength of students' group commitment—that is, how important the university was to the individual students' sense of identity. Once the students were sorted out according to their group allegiances, they were all asked to review the university's grievance procedures. In actuality, some participants read procedures that seemed just and fair, while others read a version that clearly disrespected students' rights.
Then, the researchers asked the students a series of questions about their willingness to serve their schools and fellow students in selfless ways: Would they tutor another student if asked? Would they help a professor with some photocopying?
As reported in a recent issue of Psychological Science, a journal of the Association for Psychological Science, the students who were the most devoted to their school to begin with were also the most cooperative and helpful when forced to confront the school's failings. That is, those truest to their group redoubled their sense of service and commitment when faced with injustice. These results were immediate and short-term. That is, while some students stayed to help strengthen the group and correct its course, their commitment was unlikely to last for long.
It seems, then, that if confronted with continued evidence of unfairness and injustice, people will stop compensating for the group's shortcomings and leave. What is unclear is how long this will take or how unjust a group must be before it squanders its members' loyalty.
