The real purpose of the scientific method is to make sure Nature hasn't mislead you into thinking you know something you don't actually know.

—Zen and the Art of Motorcycle Maintenance

I occasionally read books about science, pseudo-science, and just generally sorting out what is actually true from what you think is true1... and while those books do a good job of laying out the problem, this formulation really resonated with me... though Nature isn't generally the one doing the tricking.
