Goodman’s solution to the new riddle of induction resembles Hume’s solution in an important way. Instead of providing a theory that would ultimately justify our choice of predicates for induction, he develops a theory that provides an account of how we in fact choose predicates for induction and projection. Goodman observes that predicates like “green” are favored over predicates like “grue”, because the former are much better entrenched, i.e., in the past we projected many more hypotheses featuring “green” or predicates co-extensional with “green” than hypothesis featuring the predicate “grue”. If two hypotheses are the same with respect to their empirical track-record, then the hypothesis that uses the better entrenched predicates overrides the alternatives. On the basis of these considerations, Goodman defines projectibility (and cognates) for hypotheses (FFF, 108):
