Generalized trust is diminished among black Americans firsthand by experiences of bias and from contending with social and physical disorder in their neighbourhoods, then secondhand through bias socialization.

Something I found particularly interesting:  Racial minorities tend to be lower in generalized trust, and those who are lower in generalized trust are less likely to act as brokers to connect those in their social networks with jobs they’ve heard about. Interesting challenge in terms of equality/diversity in labour markets.
