Nowhere are the battle lines more deeply drawn in usage questions than over the difference between disinterested and uninterested. According to traditional guidelines, disinterested should never be used to mean ‘not interested’ (i.e. it is not a synonym for uninterested) but only to mean ‘impartial’, as in the judgements of disinterested outsiders are likely to be more useful. Ironically, the earliest recorded sense of disinterested is for the disputed sense. Today, the ‘incorrect’ use of disinterested is widespread: around a quarter of citations in the Oxford English Corpus for disinterested are for this sense.
