### Supporters

Putnam's most consequential refinement is the distinction between bonding and bridging social capital. Bonding social capital binds homogeneous groups—kin, caste, ethnic, or religious in-groups—reinforcing solidarity and mutual support among people who are already alike. Bridging social capital connects heterogeneous groups across social cleavages, linking people of different backgrounds through cross-cutting associations. Bonding ties provide a thick safety net but can entrench exclusion and parochialism; bridging ties are thinner but generate broader reciprocity and information flow across society. A third variant, "linking" social capital, later elaborated by Michael Woolcock and others at the World Bank, describes vertical connections between citizens and institutions of power, enabling communities to access resources held by formal authorities.

### Opponents

The concept has drawn sustained criticism. Critics including Alejandro Portes warned of a "dark side" of social capital, in which tightly bonded networks—mafias, exclusionary clubs, communal vote banks—produce cooperation for antisocial ends and impose conformity costs on members. Theda Skocpol argued that Putnam underweighted the role of state structures and large-scale political organisation in the decline of American civic life, attributing too much to individual choices such as television viewing. Others questioned the measurement of a slippery, multidimensional concept and the direction of causation between trust and good governance. Recent scholarship examines whether digital platforms and social media build bridging ties or merely amplify bonding within echo chambers—a question Putnam himself flagged as unresolved.

Robert Putnam's 2000 book Bowling Alone documented that US bowling league membership collapsed even as total bowlers rose, symbolising the erosion of America's bridging social capital and civic associational life.
