Politicians are better at estimating public opinion when they think it is more salient

Politicians' perceptions of public opinion matter for substantive representation, but previous work has concluded that they do not have very accurate perceptions of voters' policy preferences. We add to the debate on the drivers of perceptual accuracy by exploring whether politicians have a more accurate understanding of public opinion when it matters either to voters or themselves, or when politicians think it matters more to voters. Drawing on survey data collected among elected representatives and citizens in Belgium, Canada, Switzerland, and Germany, we show that politicians have a better understanding of public opinion when they think the issue matters to voters. Further, when an issue is personally important to politicians they more accurately estimate their party supporters' opinions. The results confirm that politicians hold more accurate perceptions of voters' preferences when they think it is important to do so, but not necessarily when the issues actually are important to voters.
