Anchoring political preferences: The structural bases of stable electoral decisions and political attitudes in Britain

Abstract. The paper applies a structural perspective to the analysis of political preferences. Examining two British surveys, the 1987 cross–section of the electorate and a panel survey that covers the 1983 and 1987 elections, the research explores the bases of persistent voting for the same party, location on left–right scales, and the probability of holding the same policy views on a host of different issues over time. A set of structural variables rests at the heart of the paper's theory: discussion networks, patterns of interactions with members of political parties, social class networks, and location in the social structure. Several hypotheses guide the analysis: The effects of the structural variables on the probability of casting a ballot for the same political party in any one election and in adjacent elections will remain, even after controlling for party identification; political party socialization; location on left–right scales; positions taken on any and all political issues; age, and past levels of electoral stability. The effects of structural variables on left–right position will remain, even after controlling for locations on alternative left–right scales. Finally, reinforcing attitudinal context provides the only consistent determinant of stable policy positions, after controlling for a host of alternative explanations including level of education; age; interest in politics, and a general propensity to offer stable answers to political questions.
