This video was published by the Richard Dawkins Foundation in June this year.
The original kit was published as Chapter 12: The Fine Art of Baloney Detection in Carl Sagan’s book The Demon-Haunted World: Science as a Candle in the Dark (ISBN 0-394-53512-X / ISBN 0-345-40946-9). This site from the Australian Volunteer Coordinators for The Planetary Society has a neat summary, and the whole chapter is excerpted here. I like Sagan’s conclusion:
Like all tools, the baloney detection kit can be misused, applied out of context, or even employed as a rote alternative to thinking. But applied judiciously, it can make all the difference in the world — not least in evaluating our own arguments before we present them to others.
While I’m recommending material that promotes rational thinking, I’ll put in a plug for the 1841 classic Extraordinary Popular Delusions and the Madness of Crowds by Charles Mackay. The chapters on economic bubbles should be mandatory readings for all bankers and stockbrokers, just for a start.
