The Best Test Theory of Extension (BTT) offers a solution to the disjunction problem. According to BTT, the extension of a natural kind term t in a given subject S’s language of thought (LOT) consists of the members of the natural kind that has the highest success rate relative to t . We calculate the success rate of natural kind K relative to S’s term t by dividing the number of times members of K have caused S to token any LOT term whatsoever into the number of times members of K have caused S to token t .
