The fact of the matter is, you can't trust anyone. Your favorite news anchor may be lying through her teeth and not even know it. That great science article you read could be paid propaganda. The statistics you repeat could be so wrong they are laughable.
So, a thread on media manipulation. Or, How to be a good skeptic. Please feel free to add thoughts and links.

* You think that nonprofit organizations just give away their stamps of approval on products? Bristol-Myers Squibb paid $600,000 to the American Heart Association for the right to display AHA's name and logo in ads for its cholesterol-lowering drug Pravachol. Smith Kline Beecham paid the American Cancer Society $1 million for the right to use its logo in ads for Beecham's Nicoderm CQ and Nicorette anti-smoking ads.
* You think that you're witnessing a spontaneous public debate over a national issue? When the Justice Department began antitrust investigations of the Microsoft Corporation in 1998, Microsoft's public relations firm countered with a plan to plant pro-Microsoft articles, letters to the editor, and opinion pieces all across the nation, crafted by professional media handlers but meant to be perceived as off-the-cuff, heart-felt testimonials by "people out there."
* You think that a study out of a prestigious university is completely unbiased? In 1997, Georgetown University's Credit Research Center issued a study which concluded that many debtors are using bankruptcy as an excuse to wriggle out of their obligations to creditors. Former U.S. Treasury Secretary Lloyd Bentsen cited the study in a Washington Times column and advocated for changes in federal law to make it harder for consumers to file for bankruptcy relief. What Bentsen failed to mention was that the Credit Research Center is funded in its entirety by credit card companies, banks, retailers, and others in the credit industry; that the study itself was produced with a $100,000 grant from Visa USA and MasterCard International Inc.; and that Bentsen himself had been hired to work as a credit-industry lobbyist.
* You think that all grassroots organizations are truly grassroots? In 1993, a group called Mothers Opposing Pollution (MOP) appeared, calling itself "the largest women's environmental group in Australia, with thousands of supporters across the country." Their cause: A campaign against plastic milk bottles. It turned out that the group's spokesperson, Alana Maloney, was in truth a woman named Janet Rundle, the business partner of a man who did P.R. for the Association of Liquidpaperboard Carton Manufacturers-the makers of paper milk cartons.
* You think that if a scientist says so, it must be true? In the early 1990s, tobacco companies secretly paid thirteen scientists a total of $156,000 to write a few letters to influential medical journals. One biostatistician received $10,000 for writing a single, eight-paragraph letter that was published in the Journal of the American Medical Association. A cancer researcher received $20,137 for writing four letters and an opinion piece to the Lancet, the Journal of the National Cancer Institute, and the Wall Street Journal. Nice work if you can get it, especially since the scientists didn't even have to write the letters themselves. Two tobacco-industry law firms were available to do the actual drafting and editing.
