If its goal was to prove that neoclassical economics is based on an erroneous assumption, then it was successful. However, it's worthwhile emphasizing that behavioural economics findings taken seriously by thousands of psychologists, marketers, writers, politicians, civil servants, and laypeople are a load of cobblers.
