ENCORE Are you skeptical?  Sure, you raise an eyebrow when some Nigerian prince asks for your bank numbers, or when a breakfast cereal claims that it will turn your kid into a professional athlete overnight. But what do you really know about the benefits of organic milk?  Or the power of whitening ingredients in your toothpaste?  How credible is what you read on Twitter? Today, information overwhelms us, and the need to keep our skeptical wits about us has never been greater.  We follow Seth around as he faces the daily onslaught of hype and hokum.
