...the main problem in America is that the public, including its highly educated members, is social-scientifically ignorant. Most people I talk to about policy do not even realize that there is anything non-trivial about policy analysis. They want the government to make sure that four phases of rigorously designed RCTs be performed before drugs are made available to the public, for fear of unintended consequences of intervening on a complex system like the human body, yet they think they understand the consequences of highly complex interventions on human societies by introspection alone. Not only do they think they understand the consequences of alternative policy choices, but they're so confident that their understanding is right and that its truth is so obvious that the only explanation for disagreement is evil intentions.
When I point out that on virtually every policy issue, at least somewhat compelling arguments for many conflicting points of view have been made by relevant experts, people usually react in disbelief or denial, or immediately retreat to questioning the motives of these experts ("of course they say that, they're on the payroll of Big Business" or whatever). These patterns of speech and behavior are uniformly distributed across the political spectrum, even if intelligence and knowledge of well-established facts is not. Even many experts in particular areas of social science evince no awareness of the lack of expert consensus on almost anything in their field, and give the impression of unanimity to an unknowing public.(Emphasis in the original.) The rush to bulverism (evil intentions or corruption of people who disagree) is particularly noticeable in economic commentary. Uncertainty about policy is especially strong in macroeconomics and finance. That doesn't mean anything goes. Many arguments do violate basic budget constraints or suffer other obvious logical flaws.
How do you know economists have a sense of humor? We use decimal points.
