If depression “runs in families”, it is at least partly genetic, as many claim. But greed, atheism, criminality and more can “run in families” as well, which raises many ethical issues and problems. Some scientists even claim there is a gene for spirituality. With eugenics as the origin of the “runs in the family” concept, reductionism and the now known complexity of genetic effects, the genetics of mental illness is seriously flawed.
Psychiatry claims that mental illness has a genetic basis. Schizophrenia is often cited as the best example of “behavioural genetics”. There are at least ten reasons why this is not possible. Yet this belief continues in the mental health profession as if it were fact and hence is actually a modern myth.
