Citizens' ability to make informed and thoughtful choices when voting for policy proposals rests on their awareness of and access to accurate information about the costs and benefits that each proposal entails. We study whether certain social factors affect the disposition to drop a misconception, the belief that rent control increases the availability of affordable housing. We design an on-line experiment to test whether giving voice, aggregate social information and disaggregate social information increase the effect of a video explaining the evidence on the consequences of rent control policies. While voice and aggregate social information do not have an additional effect relative to a control group that is shown the same video, supplying information about how other groups of people react to the same information has an additional impact on updating beliefs. Furthermore, we find that updating beliefs widely translates into intended voting and recommending the video. Finally, although ideological position and a zero--sum mentality are correlated with the initial misconception, these two factors do not thwart the disposition to update beliefs after receiving experts' information.
