In environments without transfers, such as refugee resettlement, school choice, organ transplants, course allocation, and voting, we show that Random Priority is the unique mechanism that is obviously strategy-proof, Pareto efficient, and symmetric; hence providing an explanation for the popularity of this mechanism. We also construct the full class of obviously strategy-proof mechanisms, and explain why some of them are more popular than others via a natural strengthening of obvious strategy-proofness.
