Commentary on Linda Mealey (1995), The sociobiology of sociopathy: An integrated evolutionary model

[SFS] When Genotype × Environment (G × E) interactions are present, heritability estimates are not interpretable. Mealey cites abundant evidence for G × E interactions in the etiology of sociopathy, thereby completely undermining estimates of the heritability of sociopathy which form the foundation of her model. Without proper evidence for a genetic basis of sociopathy, Mealey’s sociobiological model collapses under its own great weight. [LM] It is impossible to discuss the constructs “heritability,” “theory of mind,” and “normality” in a single coherent essay. The following three rejoinders address each of these exceedingly complex constructs individually, as each relates to the two-path model of sociopathy and psychopathy
