If you have a dimmable lightbulb and always turned it to partial brightness, would it last longer than a lightbulb always turned to full brightness?

Yes, for an incandescent bulb the lifetime has been estimated to be a function of the reciprocal of the 13th power of ~~current~~ voltage. The hotter the filament, the more tungsten evaporates from the filament.  At half level you've got a lifetime bulb. 

Other types of bulbs also last longer when dimmed for different reasons.

Edit: changed current to voltage.
