Media and Autism

Bill Ahearn has sharply critical words for media coverage of autism:
Andrews et al. (2002) found that parents of children with autism diagnosed after the MMR controversy was publicized in the media were more likely to report the onset of autism as just after MMR vaccination than were parents of children with autism diagnosed before the controversy. The impact of the media's coverage of this issue has had a significant and detrimental influence. Unfortunately, highly improbable events, extraordinary claims implying a conspiracy, and steadfast beliefs with little support beyond anecdote tend to given more coverage than sound information based upon empirically valid and peer reviewed research.

Ahearn adds: "Another typical tactic of the media is to present controversial topics as if there are two, equally relevant sides to the story." Some media critics see a similar "false balance" in coverage of other issues, such as climate change.
