False balance, also referred to as false equivalence, is a real or perceived media bias, where journalists present an issue as being more balanced between opposing viewpoints than the evidence actually supports. Journalists may present evidence and arguments out of proportion to the actual evidence for each side, or may censor information which would establish one side's claims as baseless.
For example, "Objective coverage" of lynching in the 1890s by US journalists failed "to recognize a truth, that African-Americans were being terrorized across the nation." False balance is often found in political reports, company press releases, and general information from entities with special interest groups in promoting their respective agendas.
Other examples of false balance in reporting on science issues include the topics of man-made vs. natural climate change, the relation between Thiomersal and autism and evolution vs. intelligent design. For instance, although the scientific community attributes a component of climate change of the last 50–100 years, particularly global warming, to the effects of the industrial revolution, there are a small number of scientists who dispute this conclusion. 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 favoring anthropogenic global warming.
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 actually 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.
A study conducted by Jules Boykoff and Maxwell Boykoff found that in the case of global warming, for example, a much more apparent consensus within the scientific community had been reached than the media made it seem. NASA scientist James Hansen testified before Congress in 1988 that he was "99 percent certain" burning fossil fuels was one of the factors that caused temperatures to rise. That same year, the United Nations formed the Intergovernmental Panel on Climate Change (IPCC), which went on to produce a steady stream of reports supporting the case that humans are contributing to global warming. Yet, while over 3,500 articles on global warming appeared between 1988 and 2002 just in The New York Times, The Wall Street Journal, The Washington Post, and The Los Angeles Times, 53 percent of these stories gave roughly equal attention to scientists who expressed views that global warming was caused by humans as they did to those who said global warming was caused by nature.
Jules and Maxwell Boykoff use the lead paragraph of a 1992 front-page article from The Los Angeles Times, as an example:
- The ability to study climatic patterns has been critical to the debate over the phenomenon called "global warming." Some scientists believe—and some ice core studies seem to indicate—that humanity's production of carbon dioxide is leading to a potentially dangerous overheating of the planet. But skeptics contend there is no evidence the warming exceeds the climate's natural variations.
This paragraph puts scientists against climate change deniers, as though both are on equal grounds of knowledge, when in reality the scientists (even in 1992) have far more reason to believe that humanity is causing temperatures to rise than "skeptics" have to disagree.
