Does switching a light on and off damage the bulb more than just leaving the bulb on?

I'm curious because one light in the house, which is turned on and off dozens of times an hour, seems to go out slightly more often than any of the other lights in the house which are left on pretty much all the time.

I would think that for metal filaments in light bulbs, being turned on and off repeatedly would lead to repeated episodes of thermal expansion and contraction, which would eventually lead to metal fatigue and fracture of the filament.
