Probabilistic epigenesis is a way of understanding human behavior based on the relationship between experience and biology.[1] It is a variant form of epigenetics, proposed by American psychologist Gilbert Gottlieb in 1991.[1] Gottlieb’s model is based on Conrad H. Waddington's idea of developmental epigenesis.[2] Both theories examine the complexity of the ways in which the brain develops and explore factors that occur outside the genome.[2] However, probabilistic epigenesis differs from Waddington’s model as it relies much more heavily on the potential developmental impacts of experience and environment and how they interact with an individual’s genes.[2] Probabilistic epigenesis takes into account developmental, hormonal, environmental, neuropsychological, and genetic factors in order to explain various forms of behavior.[3]
