Data from Great Britain acid the United States from the late 1950s to the e
arly 1990s show relatively little change in the frequency with which citize
ns engage in political discussions, with whom they are likely to speak, and
the variables that shape their propensity to engage in political talk. In
addition, analyses of the data show that discussing politics enhances citiz
ens' knowledge of public affairs, even net of other variables known to affe
ct political knowledge. Students of political behaviour and those intereste
d in strengthening democracy need to treat political discussions as an impo
rtant form of political participation.
