I share Noah Smith’s enthusiasm for experiments in economic policy. I subscribe to the philosophy that (perhaps charitably) models folks’ political biases as strong Bayesian priors. Whenever we have weak evidence, we are pulled to favor the hypothesis that leans strongest toward our biases while still being minimally compatible with the evidence. Although folks’ beliefs would track truth better if they could reduce bias, and I am pessimistic about this improving, we can still pull different sides together by compiling better evidence.
There are uncountable fierce political battles that are usually considered intractably ideological, but which I have been convinced by others actually would yield considerably under the introduction of robust, unambiguous evidence. It’s darkly satisfying to think “my opponent ignores reason, so it doesn’t matter what evidence we collect; I’ll just have to beat him with rhetoric”, but this is a mistake largely grounded in a lack of appreciation for how weak the evidence we typically collect really is. Most of the vast resources we individuals put into pitched verbal battles would be better spent on ambitious controlled experiments, e.g., Robin Hanson’s call for larger scale version of the Oregon Medicaid and RAND health insurance experiments.
