The Biases of Bureaucrats

"[While] there is a lot of interest in the psychology and neuroscience of markets, there is much less in the psychology and neuroscience of government. Slavisa Tasic, of the University of Kiev, wrote a paper recently for the Istituto Bruno Leoni in Italy about this omission. He argues that market participants are not the only ones who make mistakes, yet he notes drily that "in the mainstream economic literature there is a near complete absence of concern that regulatory design might suffer from lack of competence." Public servants are human, too.

Mr. Tasic identifies five mistakes that government regulators often make: action bias, motivated reasoning, the focusing illusion, the affect heuristic and illusions of competence."
