<p>In an intensive kinship society, individuals naturally have a sense of trust in their relatives and remain wary of strangers (a sense of distrust). However, an individual’s perception of collective norms, kinship intensity, and group affiliations may change with the diverse social interactions in his own interpersonal circle. The current research examines whether occupational diversity can reduce the gap between trust in relatives and trust in strangers. With a large national sample (Study 1), the findings indicated that direct diverse social networks have an inhibiting effect on trust in relatives and a facilitating effect on trust in strangers. Experimental studies found that focusing on the network diversity of one’s occupational ties can affect trust in relatives negatively and strangers positively (Study 2), and the positive perception of occupational diversity acted as a moderating variable for diversity to function (Study 3). The findings underline the “kinship estrangement effect” of occupational diversity in shaping an individual’s trust in relatives and nonrelatives, especially in family-oriented culture.</p>
