概要	A misinformation correction experiment tests whether a factual correction can reduce belief in a political misperception. In Nyhan and Reifler's influential 2010 design, all respondents read a misleading claim and a random subset also read a correction, after which their factual beliefs are measured. Their alarming finding was a backfire effect: for some groups, corrections increased rather than decreased misperceptions among those ideologically threatened by the fact. Later large-scale replications by Wood and Porter found backfire to be rare and corrections generally effective, making this design a case study in how political psychology refines a striking result through replication.	The partisan motivated reasoning paradigm is the experimental template for showing that citizens process political information to protect their existing loyalties rather than to reach accurate conclusions. In Taber and Lodge's foundational 2006 design, partisans who read balanced pro and con arguments rated congenial arguments as stronger, spent effort counterarguing uncongenial ones, sought out confirming information, and ended up more extreme than they began. Martin Bisgaard's later work extends the logic to facts, showing that even when partisans accept the same factual reality they reinterpret who deserves credit or blame, so getting the facts right can paradoxically fuel rather than dampen partisan reasoning.
