False balance, known colloquially as 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 often 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, although in reality they are not, therefore creating doubt about the scientific state of research. This 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. False balance can be the result of viewpoint discrimination or political bias. Political bias can be evaluated relative to the median voter for particular topics.
