Nudge VS Sludge

The book Nudge by Richard Thaler and Cass Sunstein has been described as "the most impactful book on behavioural economics". The core concepts in the book have found the way into large corporations and even entire political teams have been formed called 'nudge units' to implement the ideas in the book.  The benefit I can offer you as someone who has read 500+ books and podcasted about 350+ of them is that I can bring different ideas from different books together to add depth to the arguments.  So rather than just sharing the ideas from Nudge, I'm going to mix it together with the ideas from Sludge by Cass Sunstein (not sure why Thaler didn't get the co-author gig on that one!) and pull out the common threads.  After defining and explaining what "nudge" and "sludge" are, along with some real-world examples, I bring together a nice little 2x2 matrix that compares how nudge and sludge can be used for GOOD... or for EVIL.
