There are two species of behavioral economists - those that mostly ignore classical economic theory and manage to accomplish some interesting tasks and those bent on disproving classical economic theory.   The latter often fall in to the same confirmatory fallacy they are apt to criticize in others.  Furthermore, they rarely extract the most powerful findings apparent in their research, as they are more hung up on disproving than proving.

The first category are talented observers and usually good reads.   The second slip easily in to politicized amateurism.

Unfortunately, with respect to our new ruling class, the second formulation appears to have won the day.
