Persistent Polarizing Effects of Persuasion: Experimental Evidence from Turkey
研究在土耳其公投前，关于行政绩效或行政权力扩张的信息宣传如何加剧选民对公投的极化，并在后续选举中改变党派归属，导致党派极化。
I evaluate randomly varied neighborhood exposure to information campaigns regarding either executive performance, or increases in executive power, prior to a Turkish referendum on weakening checks and balances on the executive. The campaigns increased voter polarization over the referendum, and subsequently changed party affiliation in national and local elections over the next two years, leading to partisan polarization. My results suggest that, when voters disagree on whether increasing executive power is a good policy, more information can increase voter polarization. Finally, I conclude that because potential polarization is often ignored, the impact of information campaigns on civil society is underestimated.
