This week we start with a discussion of assumptions, as Ben brings two outrage-provoking news stories that turned out to not be what was originally assumed.

What's the lure behind easy, supposed panaceas in the form of some kind of concentrated oil that are rumored to cure everything? Has the medical community found any of them measurably useful for any conditions?
