简答题:People generally assume that when they consider another person a "friend," that person also thinks of them as a friend, which means friendship is mutual.But when we analyzed self-reported relationship surveys from several experiments around the world, we found that while most people assume friendships are two-way,only about half of friendships are indeed mutual.These findings indicate a profound inability of people to know who their friends are.
In itself this may seem like an interesting but minor finding, but this large proportion of unbalanced friendships translates to a major effect on the ability of an individual to persuade others to cooperate or change their behavior.
That's because success depends on the ability to recruit friends to help at critical times.Studies have shown that social influence is a critical factor in organizational change, and especially in the propagation of new behaviors, new ideas, and new methods in both organizations and society.
