Friends bolster health and happiness, with friend preferences directing us toward friends who can facilitate this. Intuition and research alike suggest people prefer friends to be kind and trustworthy and disfavor viciousness and indifference (and befriend the similar, familiar, nearby). Taking a target-specific approach, we predict and find people possess preferences not only for how friends should behave toward us, but—because our friends interact with others, and these interactions can affect us—people also possess nuanced, distinct preferences for how friends should behave toward others: (a) When targets of friends’ behavior are unspecified (reflecting previous work), preferences track how people want friends to behave toward us. In line with that work, (b) people want friends to be kinder and more trustworthy than not. But (c) people also want friends to be more prosocial toward us than toward others and (d) sometimes want friends to be more vicious than prosocial—toward our rivals.
