Abstract: In the study of behavioural heritability, a few methods have been used throughout history, beginning with the tracking of familial diseases, advancing into family studies, twin studies, adoption studies, and statistical ANOVA methods. These methods are discussed and evaluated for the strength of their support of the idea that behaviour is indeed heritable, and to what extent this is the case. Results show that, while great pains were taken to buttress these methods against epistemological scepticism, none have been able to fully and definitively prove the genetic heritability of behaviour, while there has been much said in criticism of the methods employed.
