"There's a sucker born every minute." What's kind of funny about that famous quote is that there is no record of P.T. Barnum ever saying it, and there's a lot of evidence he was too smart to have done so. Whether Barnum made the observation or whether those words were uttered by any number of con men instead, the fact remains we are often excessively gullible. After watching members of the House Committee on Science, Space and Technology debate climate change last week, I'm not finding this at all endearing.
