In "The Psychological Foundations of Culture", Tooby and Cosmides critique what they call the 'SSSM', short for 'Standard Social Science Model'. The term refers to a metatheory that the authors claim has dominated the behavioral and social sciences throughout the twentieth century, blending radical environmentalism with blind empiricism. The SSSM has retained and reified the nature/nurture dichotomy, and its practitioners have meticulously amassed evidence over the years which 'proves' that the overwhelming majority of psychological phenomena fall in the 'nurture' category. Only some instinctive and primitive biological drives like hunger and thirst have been retained in the 'nature' category.
