Information conveyed as credible but later amended can affect people's memory and reasoning after retraction. Misinformation differs from concepts like rumors because misinformation is inaccurate information that has previously been disproved. According to Anne Mintz, editor of "Web of Deception: Misinformation on the Internet", the best ways to determine whether information is factual is to use common sense. Mintz advises that the reader check whether the information makes sense and whether the founders or reporters of the websites that are spreading the information are biased or have an agenda. Professional journalists and researchers look at other sites (particularly verified sources like news channels) for that information, as it might be reviewed by multiple people and heavily researched, providing more concrete details.
