The Fine Art of Baloney Detection

Carl Sagan
Posted: October 26, 2009.

Print: The Demon-Haunted World

In science we may start with experimental results, data, observations, measurements, “facts.” We invent, if we can, a rich array of possible explanations and systematically confront each explanation with the facts. In the course of their training, scientists are equipped with a baloney detection kit. The kit is brought out as a matter of course whenever new ideas are offered for consideration. If the new idea survives examination by the tools in our kit, we grant it warm, although tentative, acceptance. If you’re so inclined, if you don’t want to buy baloney even when it’s reassuring to do so, there are precautions that can be taken; there’s a tried-and-true, consumer-tested method.

What’s in the kit? Tools for skeptical thinking.

What skeptical thinking boils down to is the means to construct, and to understand, a reasoned argument and—especially important—to recognize a fallacious or fraudulent argument. The question is not whether we like the conclusion that emerges out of a train of reasoning, but whether the conclusion follows from the premise or starting point and whether that premise is true.

Great quote and great book! Very simple but powerful idea: do we concern ourselves in life with what makes us feel good or with what is true? Evolution probably has us wanting a bit of both. However, eyes which open to see the power to manipulate the human desire for feeling good might do one of two things: benefit personally or demand truth!

In complete honesty it gives me a sick feeling to see Carl Sagan’s work on this site.

I don’t know why this is here, but I’m begging you not to make a habit of offering Carl Sagan’s work on this site, unless this site shows itself worthy.

The Reason Project is a foundation devoted to all those good things listed at the top of the page.  To add the Baloney Detection Kit from The Demon Haunted World to this site is not inappropriate.
