Higher wattage alone doesn’t make the bulb burn out faster, but the rating partially has to do with heat/fire. For example, the fixture may only be designed to handle the heat of a 40W. Put in a 60W and the heat increases, there’s not enough ventilation, and the bulb prematurely fails due to the higher heat.
