Disinterested vs. Uninterested: Usage Guide

Confusion about the meanings of disinterested and uninterested is longstanding and may be due to their tangled histories. When disinterested and uninterested entered the language in the 17th century, disinterested meant "not interested" and uninterested meant "not biased." Since then, the situation has all but reversed itself. Uninterested now means only "not interested."

uninterested in attending

Disinterested can mean either "not biased" or "not interested," but is most commonly used to mean "not biased."

the need for a disinterested referee

However, disinterested is more common than uninterested in contexts that suggest a loss of interest.

when I grow tired or disinterested in anything, I experience a disgust Jack London, letter, 1914

Still, use of the "not interested" sense of disinterested will incur the disapproval of some who may not fully appreciate the history of this word or the subtleties of its present use.
