The importance of trust has long been emphasised by social and political th
eorists from Locke and Tocqueville to Putnam and civil society theorists. H
owever, individual survey data casts substantial doubt on this powerful tra
dition of thought. There is little evidence of (1) an overlap between socia
l and political trust, (2) a syndrome of trust and membership of voluntary
organizations, and (3) the existence of trusting/distrusting dispositions a
mong individuals. However, at the aggregate national level there is evidenc
e to support the theory, and the author concludes that the classic theory i
s correct but needs modification and qualification.
