The word still has this meaning for many writers and readers; in our 2013 survey, 59 percent of the Usage Panel accepted it in the sentence The editorial writer relied on numerous factoids that have long been discredited. But factoid is also often used to mean a brief, somewhat interesting fact, and this sense has become common in recent decades.
