The '''elevator paradox''' is a [[paradox]] first noted by Marvin Stern and [[George Gamow]], [[physicist]]s who had offices on different floors of a multi-story building. Gamow, who had an office near the bottom of the building noticed that the first [[elevator]] to stop at his floor was most often going down, while Stern, who had an office near the top, noticed that the first elevator to stop at his floor was most often going up.<ref>{{Cite book |title=Digital Dice: Computational Solutions to Practical Probability Problems |first=Paul J. |last=Nahin |location= |publisher=Princeton University Press |year=2008 |isbn=978-0-691-12698-2 }}</ref> This creates the false impression that elevator cars are more likely to be going in one direction than the other depending on which floor the observer is on.
