"Motivated reasoning theory argues that when people encounter information with which they disagree, they will backlash against it and become more extreme in their prior positions . . . Coppock posits that people update their positions in ways that align with the direction of the information to which they are exposed . . . Whereas motivated reasoning theory has led to despair over the polarization of American politics, Coppock's data gives hope that information can bridge the political divide. Recommended."

“Overturning decades of conventional wisdom, Coppock compellingly demonstrates that persuasive messages have similar effects for all kinds of people. This finding will set the agenda for the fields of public opinion and political communication.”

"Persuasion is hard, but information matters—and it matters similarly to every-one. In Persuasion in Parallel, Coppock demonstrates that people’s existing views about the kind of world they want to live in are a central feature of their future views about the kind of world they want to live in, but he also shows that new information is not lost on people. Where you start has a lot to do with where you land, but making sure people get new information, more information, and factual information can move everyone’s thinking in the same direction. Politics may be polarized, but Coppock shows persuasion is not.”
