The outcome of the 2018 Quebec election was a surprise: Coalition Avenir Québec beat the Quebec Liberal Party by 12.6 percentage points, for a majority government. Not only did pollsters fail to predict this result, but the gap between the polls and the actual vote for the leading parties was the largest recorded in Quebec political polling history.

Claire Durand joins the podcast to discuss what went wrong with the pollsters’ predictions, the national and international context for political polling, and why accurate polling matters.

Claire Durand is a professor in the Department of Sociology at Université de Montréal and president of the World Association for Public Opinion Research. Her research focuses on the impact of methodologies on pre-election polling estimates.
