Prosocial behavior refers to voluntary actions intended to help others, such as helping, sharing, donating, cooperating, and volunteering. These behaviors benefit individuals or society and are motivated by empathy, concern for others' welfare, and practical or egoistic concerns. Evidence suggests prosociality is important for social group well-being. While visiting his grandmother, the author and his father encountered a homeless man begging at a traffic light. Though initially unwilling, the author's father gave the man money, prompting reflection on prosocial and egoistic motivations.
