-Thus, if there's a _cost_ associated with taking individual measurements, and the cost exceeds the amount you would save by making better decisions, then you shouldn't take the measurements. If your measurements have _error_, then your estimate of the true value of the trait being measured [regresses to the group mean](https://en.wikipedia.org/wiki/Regression_toward_the_mean) to some quantitative extent. Again, all this just falls out of _ordinary_ Bayesian decision theory, which continues to work even when some of the hypotheses are about groups of people.
+Furthermore, it's not obvious that the law should behave any differently in this respect than a private individual: is Governance supposed to be _less_ Bayesian _because it's Governance_?! (Although, perhaps there's a distinction between the "law" and "public policy" functions of Governance, with the former laying out timeless rights and principles, whereas day-to-days decisions about the empirical world are farmed out to the latter?)
