Great. Thanks. You named 4 principles while you list only three; trade off, opportunity cost and incentives. Where is the fourth? You explained the OC only!
What I say is that it links back to 3 OF THE 4 of the principals (not yelling but can't underline or change the color) of how humans make decisions - that is from Chapter 1 where I break down the 10 basic principals into 3 groups - the first group had 4 principals - I hope that explains it
