The paper explores an important feature of many university rankings: they are not immune to the so-called reversal effect. The effect consists in the fact that the order in the hierarchy between two universities may depend on the addition or the removal from the pool of relevant institutions of a university, or to changes in the scores obtained by other universities. Simplified as well as real-life examples are offered. It is argued that the reversal effect may consist in unexpected, while unreasonable changes in the hierarchy of universities or study programs.
