False balance, also bothsidesism, is a media bias in which journalists present an issue as being more balanced between opposing viewpoints than the evidence supports. Journalists may present evidence and arguments out of proportion to the actual evidence for each side, or may omit information that would establish one side's claims as baseless. False balance has been cited as a cause of misinformation.

False balance is a bias which usually stems from an attempt to avoid bias and gives unsupported or dubious positions an illusion of respectability. It creates a public perception that some issues are scientifically contentious, though in reality they may not be, therefore creating doubt about the scientific state of research, and can be exploited by interest groups such as corporations like the fossil fuel industry or the tobacco industry, or ideologically motivated activists such as vaccination opponents or creationists.

Examples of false balance in reporting on science issues include the topics of human-caused climate change versus natural climate variability, the health effects of tobacco, the alleged relation between thiomersal and autism, alleged negative side effects of the HPV vaccine, and evolution versus intelligent design.
