Earlier today, I posted on the recent paper that claims to have found a link between eating genetically modified corn and the growth of tumors in rats. Short version: The research sucked. It's a terribly done study and it demonstrates why "peer reviewed" does not always mean "accurate".
But now, this story is getting worse. Turns out, the authors of the study (and their financial sponsor, The Sustainable Food Trust) manipulated the media to ensure that the first news stories published about the study would not be critical of its methods or results.
First, some background. When a journal is about to publish a study that they think will be big news, they usually offer the full study to reporters under an embargo system. The reporter gets to read the study, do their reporting, and write a story ... but they can't publish that story until a specific day at a specific time. If you're a daily or an online publication, there's a lot of pressure to have your story ready to go the moment the embargo lifts. Otherwise, you'll look like you weren't on the ball. There's a lot of problems with this system, but it's very common.
What's not common: Forcing journalists to sign non-disclosure agreements promising to not show the study they're reporting on to any independent researchers or outside experts. If you're trying to make sure your publication runs a story on the study right when the embargo lifts, but you can't show the study to any third-party experts before the embargo lifts, then the story you run is going to (inevitably) contain only information the authors of the study want you to talk about. It ceases being journalism and becomes PR.
This is what the authors of the GM corn/rat tumor study did.
