I never liked those Scientific Method posters. Or the equivalent lists that occupied Chapter One of so many science textbooks. They seemed too sterile and prescribed, and made science seem like a very clean business carried out by automatons.
So my pulse raced on my first viewing of The Mechanical Universe episode devoted to The Millikan Experiment. The narrative trashes the so-called scientific method. I thought that was fairly bold for a program devoted to science. The Mechanical Universe story laid out the fact that scientists are biased when they enter the lab. They usually know what they're looking for. And so on. It went on to describe how science succeeds despite scientists.
While working on my Master's degree, I found out that the "scientific method" as outlined in posters and schoolbooks was the creation of an education academician. No wonder I didn't care for it!
Carl Sagan suggested we need a Baloney Detection Kit when evaluating scientific claims. Michael Shermer describes, in detail, what such a kit might include. Here it is in video form.
I think a poster form of this Baloney Detection Kit would be a better use of precious science classroom real estate than those tired Scientific Method posters. Even better: a bulletin board where examples of pseudoscience can be added, organized by their most obvious baloney flags. Just a thought.
