Proportional representation and attitudes about politics: results from New Zealand

PR systems often are credited with producing more equitable outcomes between political parties and encouraging wider social group representation than majoritarian systems. Theory suggests that this should instill greater trust, efficacy, and faith in the political system. We assume that citizens disadvantaged by majoritarian rules (political minorities) will have a relatively greater shift toward positive attitudes about democracy following a transition from a majoritarian system to proportional representation. We employ panel data from the 1993–1996 New Zealand Election Study (NZES) to test hypotheses about the effects of electoral system change on attitudes about governmental responsiveness, trust in government, and political efficacy. We find that there is a general shift in mass opinion toward more positive attitudes on some measures of efficacy and responsiveness. Political minorities display a greater shift toward feelings of efficacy than other voters.
