Providing climate skeptics a voice in “balanced” mainstream media coverage skews public perception of the scientific consensus regarding climate change, leaving viewers less likely to understand the threat of climate disruption and less likely to support government actions to address global warming, according to the results of a Stanford University research effort.
The Stanford researchers probed the impact on public understanding of climate change when media coverage features a climate skeptic alongside a climate scientist. Media stories featuring only a mainstream climate scientist “increased the number of people who believed that global warming has been happening and that humans have caused global warming.”
However, when media stories also include a climate skeptic, ostensibly to add “balance” to the story, the result is a “significantly reduced” number of people who understand the issue and endorse government action to address the problem.
“Watching a skeptic decreased perceptions of consensus among scientific experts, and this decreased perception of consensus led respondents to be less supportive of government action in general and of cap and trade policy in particular,” the researchers found.
