When making policy about complex phenomena, politicians can only guess which experts to attend to, and which to ignore. There is no reason to assume that such guesses hit their marks more often than not or, indeed, that they tend to improve the relevant circumstances rather than make them worse. Policymakers do not have access to interdisciplinary experts about complex, multi-causal phenomena. Such experts do not exist.
