Coppock on CNN: Do Political Lawn Signs Affect Election Outcome?
October 19, 2020
Are campaign yard signs effective advertising? Do they change anyone’s mind?
Professor Alex Coppock was on CNN with host Michael Smerconish to discuss his findings of an randomized experiment he did on the 2016 presidential elections. In that paper, “The Effects of Lawn Signs on Vote Outcomes: Results from Four Randomized Field Experiments in 2016” published in Electoral Studies, Coppock and his co-authors find that the answer is yes, there is a small but detectable amount that lawn signs sway peoples’ votes.
