Behavioral economics faces its limits

Behavioral economics seems to have reached that point where, according to Thomas Kuhn’s theory, paradigms face puzzles they can’t explain and anomalies start to pile up. Attacks come from evolutionary psychologists and thinkers from other fields. I think the main point for social marketers is a criticism that has been croppinp up in such attacks: that real social problems demand much more than simple nudges. It is easier to push for more efficient vehicles, but what about the more efficient tax on carbon? (This is a point made by the great BE George Loewenstein who claims that BE is not a substitute for mainstrem economics). This is why I became a fan of systems modelling. To create social change we must identify the real leverage points of change. BE solutions often obfuscates them.
