False balance

False balance 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.

Examples of false balance in reporting on science issues include the topics of man-made versus natural climate change, the alleged relation between thimerosal and autism[1] and evolution versus intelligent design.[2]

False balance can sometimes originate from similar motives as sensationalism, where producers and editors may feel that a story portrayed as a contentious debate will be more commercially successful than a more accurate account of the issue. However, unlike most other media biases, false balance may stem from an attempt to avoid bias; producers and editors may confuse treating competing views fairly—i.e., in proportion to their actual merits and significance—with treating them equally, giving them equal time to present their views even when those views may be known beforehand to be based on false information.[3]

Examples

Climate change

False balance has been credited with spreading misinformation.[4] An example of false balance is the debate on global warming: although the scientific community almost unanimously attributes global warming to the effects of the industrial revolution,[5][6][7][8] there is a very small number, a few dozen scientists out of tens of thousands of scientists, who dispute the conclusion.[9][10][11] Giving equal voice to scientists on both sides makes it seem like there is a serious disagreement within the scientific community, when in fact there is an overwhelming scientific consensus that anthropogenic global warming exists.

MMR vaccine controversy

Observers have criticized the involvement of mass media in the controversy, what is known as 'science by press conference',[12] alleging that the media provided Andrew Wakefield's study with more credibility than it deserved. A March 2007 paper in BMC Public Health by Shona Hilton, Mark Petticrew, and Kate Hunt postulated that media reports on Wakefield's study had "created the misleading impression that the evidence for the link with autism was as substantial as the evidence against".[13] Earlier papers in Communication in Medicine and British Medical Journal concluded that media reports provided a misleading picture of the level of support for Wakefield's hypothesis.[14][15][16]
