It's most noticeable in the elevator: in tall buildings, you may see buttons for every floor except 13. For the superstitious, staying, living, or working on the 13th floor can cause a sense of discomfort, sometimes so much so that they switch floors or take their business elsewhere. But according to a 2007 Gallup poll, a whopping 87% of people don't mind staying in a 13th-floor hotel room. So why are we designing entire buildings based on a meager -- and oddly coincidental -- 13% of the population? For one thing, building owners have nothing to lose by renaming the floors, since it keeps the business of the superstitious, and the unsuperstitious don't care either way. But there's another reason: Removing the 13th floor bumps every subsequent floor up by one, so a 19-story building becomes a more impressive 20 stories, and 14th-floor rents increase to more extravagant 15th-floor prices. For building owners, superstitions are good for business.
