 Although philosophers disagree about which (if any) of these diagnoses are correct, there is almost universal agreement that our vernacular or “folk” concept of innateness is out of step with recent advances in biology and psychology. Section 3 considers several attempts to revise the vernacular concept of innateness to avoid some of its more obvious scientific pitfalls. One proposal recommends defining a trait as innate insofar is it genetically specified or encoded. Another proposal defines innateness as developmental invariance. A third defines innateness in terms of the biological property of developmental canalization. A fourth revisionist proposal defines innateness as a psychological disposition that is environmentally triggered. Each of these proposals faces shortcomings that are outlined in this entry and which suggest, to some, a very different strategy for the behavioral sciences. Instead of revising the concept of innateness to render it more scientifically accurate, another option is to eliminate the innate/acquired distinction from scientific discourse. Section 3 concludes with a review of of this eliminativist proposal.
