I wrote a paper in grad school about the word "disinterested". After a lot of research (& a period of denial), I learned when enough people use a word incorrectly in multiple formats over a long period of time, incorrect use becomes correct. In roughly 30% of documented uses, the author used "disinterested" to mean "uninterested." Therefore, it became a secondary definition. Once it's listed as one of the accepted definitions in the OED, we're all screwed. Language is unstable, sorry guys...
