You might be interested in "Christian Economics in One Lesson", a modernization of Henry Hazlitt's "Economics in One Lesson" by (in my opinion) the greatest living economist of our age, Dr. Gary North.
I'm working my way through "Thinking Fast and Slow" by Kahnemann. It doesn't have much (or any) in the way of heavy math, but it references many experiments, and the tone in general is about how easy it is to "disprove" standard economic theory.
The book I got recommended from Steve Keen, when I asked him a similar question, was J.M.Blatt: Dynamic Economic Systems. Although he has beautifully simple approach, it is really outside the standard economic theory and apart from Keen and perhaps few other individuals, sadly no one really follows in Blatt's footsteps.
keen is a complete charlatan and the laughing stock of the economic world. he doesn't even understand the basic economic theory he attempts to criticize
Are the believers in so-called "economic theory" so desperate that they have to resort to name calling?
I sincerely hope someday you would read Blatt's book with an open mind. It has nothing to do with Keen, and on few pages with a bit of matrix math he obtains far better model than economists with their supply and demand curves can ever hope. (In fact, John von Neumann apparently had fingers in it too - shame he didn't live longer, we could have a proper economic theory today.)
I'm looking for the economics equivalent of Feynman's lectures on physics.
