This talk addresses the ways in which people can be motivated to help others, especially members of outgroups. In the first part, I focus on the concept of trust, what it is, and what it is not. In second part I address social mindfulness, a new concept that focuses on seeing and acting upon opportunities to enact low-cost cooperative behavior. I report on the origins of the concept of social mindfulness, along with research on social class. Are people behaving more or less mindfully toward others from lower or higher social classes? In the third part, I discuss differences between countries in terms of social mindfulness and punishment of free-riders in social dilemmas. The bigger picture of this talk focuses on the importance of fairness and empathy, along with the more subtle mechanisms that foster trust between people.
