"Behind the most powerful manufactroversies, lies a predictable formula: first, a new problem is generated by redefining terminology.  For example, an autism 'epidemic' suddenly exists when a wide range of childhood mental health diagnoses are all reclassified as part of an autism spectrum.  The reclassification creates the appearance of a surge in autism cases, and that sets the stage for cause-seeking.

Second, 'instant experts' immediately proclaim that they have special insight into the cause.  They enjoy the authority and attention that their unique 'expertise' brings them and begin to position themselves as a 'little guy' crusader against injustice.  They also are likely to spin conspiracy theories about government cover-ups or pharmaceutical malfeasance to make their case more appealing to the media.  In many cases the experts have a financial incentive in promoting their point of view (they sell treatments or promote their books, for example).

Third, because mainstream media craves David and Goliath stories and always wants to be the first to break news, they often report the information without thorough fact-checking.  This results in the phenomenon of 'Tabloid Medicine.'

Fourth, once the news has been reported by a mainstream media outlet, the general population assumes it’s credible, and a groundswell of fear drives online conversation on blogs, websites, and social media platforms.

And finally, celebrities take up the cause while personal injury lawyers feast on frightened consumers who now believe that they are victims of harm perpetrated on them by the 'medical industrial complex.'  Meanwhile flustered government health officials have no scientific evidence of harm, but cannot prove a lack of association without further research (and that takes time).  So they offer what seems like tepid reassurances, which are perceived by some to be tantamount to an admission of guilt.

And that’s how a lie becomes an urban legend.  Perception is nine tenths of reality."
