Abstract
A crucial determinant of socially responsible behavior is the extent to which people perceive their contributions to the collective good to be effective. We suggest that the sense of connectedness to others is an important driver of the perceived effectiveness of one's actions. The more individuals feel connected to others, the more they believe that their actions have a substantial impact on the collective good. As a result, those who feel more connected are more likely to engage in socially responsible behavior. We tested these predictions in one correlational and three experimental studies, involving behavioral measures such as exerting effort in support of a pro-environmental organization and contributing financially to a social cause. The data supported the hypothesized relationship between sense of connectedness, the perceived effectiveness of one's actions, and socially responsible behavior.
