A recent article in Inc Magazine begins “As philosopher Harry Frankfurt wrote in 2005 in his classic little book On Bullshit, “One of the most salient features of our culture is that there is so much bullshit.”

The great popularizer of science, and perhaps more important, scientific thinking , Dr. Carl Sagan, would have agreed “In his book The Demon-Haunted World, he offered nine simple principles for clear thought that together he termed his “baloney detection kit.” Adopt them in your own life, and sorting truth from BS will become instantly easier.” 

This Inc Magazine article offers an executive summary of how The 9 Simple Principles in Physicist Carl Sagan’s Baloney Detection Kit Will Make You BS-Proof. Dr. Sagan also offers an in-depth essay ( 8 pages) on this topic. If you like your baloney detection kit in video form, click here.

As Mark Twain said, “It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.”
