The prejudice of journalists and news producers in the mass media in the selection of numerous events and stories that are reported and how they are covered is referred to as media bias. A number of national and international watchdog organizations report on media bias. These include the Project for Excellence in Journalism at the Pew Research Center, which monitors both print and television journalism. Media bias can take many forms including failure to cover issues that matter to minorities or women (or men), lack of diversity in news reporting sources, and/or failure to accurately report on these issues. For example, research has shown that women are under-represented in positions of power within the mainstream media. Similarly, people of color are disproportionately represented in prison systems across the world, yet there are very few reports that examine this issue from a racial justice perspective. Media bias is also demonstrated by limiting coverage of events that matter to particular groups, such as gay rights news or immigration stories, or failing to cover these topics at all. Some have argued that media bias is a natural consequence of human nature since news organizations must choose what stories to cover. Others argue that it is a deliberate strategy used by those who hold power to maintain their dominance over society. Still others claim that no matter how you slice it, media bias is bad for democracy because it limits public awareness about important issues that could affect voting choices.
