Factual corrections that target misinformation improve belief accuracy. They do so across a wide variety of countries, political beliefs and demographic characteristics. Instances of back-fire, wherein exposure to corrections reduce accuracy, are exceedingly rare and may be an artifact of research design. The evidence regarding other common concerns is mixed. While the effects on corrections on belief are not permanent, they are not entirely ephemeral, either. With some exceptions, corrections mostly only affect belief accuracy, with minor to nonex-istent influence on downstream attitudes and behaviors. While corrections are not unpopular among the public, limited available evidence suggests that those who see misinformation are exceedingly unlikely to see relevant corrections.
