چکیده

A decision maker faces a new theory of how certain events unfold over time. The theory matters for choices she needs to make, but possibly the theory is a fabrication. We show that there is a test which is guaranteed to pass a true theory, and which is also conservative: A false theory will only pass when adopting it over the decision maker’s initial theory would not cause substantial harm; if the agent is fooled she will not be harmed. We also study a society of conservative decision makers with different initial theories. We uncover pathological instances of our test: a society collectively rejects most theories, be they true or false. But we also find well-behaved instances of our test, collectively accepting true theories and rejecting false. Our tests builds on tests studied in the literature in the context of non-strategic inspectors.

'Stirrat' cried Chunky Cowan...
