 There is little cross-citation amongst these recent proposals to redefine innateness, raising two important issues for future research. First, are all these analyses extensionally equivalent, classifying traits as innate or acquired to similar degree? In particular, do they agree on cases where there has been actual scientific disagreement about whether the trait is innate, and cases which critics have used to agree that the distinction is not helpful? Second, and relatedly, although Khalidi is the only proposal explicitly restricted to one scientific field, do other analyses implicitly focus on how innateness is understood in some fields and neglect others?
