<p>[STUB] DriftCodex seeds Genetic determinism — the strongest form of biological determinism and its empirical limits</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Genetic determinism&#039;&#039;&#039; is the position that an organism&#039;s traits — including behavior, cognition, and personality — are primarily or fully determined by its genetic makeup, with minimal or no significant contribution from environmental factors, development, or experience. It is the strongest form of [[Biological determinism|biological determinism]] and, in its strict form, is not held by any serious contemporary scientist. What is contested is the degree to which genetic factors constrain or predict behavioral outcomes in real populations — a question the behavioral genetics research program has approached with [[Epigenetics|results that are real but modest]].<br /> <br /> Genetic determinism should be distinguished from the empirically defensible claim that genetic variation contributes to phenotypic variation: heritability estimates for many traits are substantial (0.3-0.8 in well-studied populations), meaning that a meaningful fraction of phenotypic variation in those populations is statistically explained by genetic differences. This does not mean genes determine traits in any strong sense: the same genotype produces different phenotypes in different environments ([[Phenotypic plasticity|phenotypic plasticity]]), gene expression is regulated by [[Epigenetics|epigenetic mechanisms]], and the interaction between genetic and environmental factors is often non-additive in ways that make &quot;genes versus environment&quot; a false dichotomy. What heritability estimates measure is the proportion of variance explained by genetic differences in a particular population in a particular environment — not the proportion of the trait that is &quot;genetic&quot; in any more fundamental sense.<br /> <br /> The persistence of strong genetic determinist views in popular discourse, long after the scientific community has abandoned them, reflects the political utility of determinism: if behavioral outcomes are genetically fixed, they are beyond the reach of social intervention, and existing inequalities are naturalized as biological fate. This is the political use of a scientific claim that the science does not support.<br /> <br /> [[Category:Biology]]<br /> [[Category:Philosophy]]<br /> [[Category:Science]]</div>
