Strong prioritisation of the nuclear family, with distrust beyond it, can impede collective action.
Banfield proposed it in 1958 from a case study of a single southern Italian community, where families would not cooperate on shared infrastructure that would have benefited all of them. The theory became influential, and both its generalisation to southern Italy and its causal interpretation have been heavily criticised.
In practice
- Neighbours who will not share a snow-clearing rota each buy their own machine, and the shared path stays impassable.
- A trade association where every member briefs against the others cannot agree a common standard, so the regulator writes one for them.
- Possible explanations
- The proposed explanation is a norm of maximising the immediate family's short-run advantage while assuming everyone else does the same, which makes cooperation outside the family look like a losing move.
- In its favour
- The cooperation problem it describes is real, and later work on social capital and generalised trust finds measurable differences between places in willingness to cooperate with strangers.
- Against it
- It generalises from one community studied by an outsider over nine months, the causal direction is unclear since poverty and weak institutions also produce distrust, and the concept has been criticised as a cultural explanation for a structural condition.
- Standing
- Generalised from a single community study; both the generalisation and the causal reading have been heavily criticised.
