This week on MIA Radio we
interview Dr Jay Joseph. Dr Joseph is a clinical
psychologist and author who brings a critical perspective to claims
in the media and the academic literature that disordered genes
underlie psychiatric disorders.
His most recent books
Trouble with Twin Studies: A Reassessment of Twin Research in the
Social and Behavioral Sciences and the 2017 e-book
and Genetics: The End of an Illusion.
In this interview, we discuss the
evidence that psychiatry puts forward in support of the claim that
mental disorders have an important genetic basis and the reasons
why psychiatry is still searching after many decades of failed
In the episode we
- How Dr Joseph, as a clinical
psychologist, came to be interested in the validity of the
diagnosis of schizophrenia.
- How he then became interested in
the assertions by psychiatry that diagnoses such as schizophrenia
had a genetic basis.
- That he discovered that the
evidence for genetic factors underlying major psychiatric disorders
is very weak and based mainly on twin and adoption
- That, despite decades of work,
there have been few if any discoveries of disordered genes that
cause the major psychiatric disorders.
- How twin and adoption studies
are used to try and demonstrate the relationship between genetics
and mental disorders.
- That people are being told that
their mental illness is genetically based which is not supported by
evidence and it is rather like the chemical imbalance myth in this
- That a disorder or condition
‘running in the family’ means that it is ‘genetic’ is also a common
- That psychiatry seems to be
focused on finding the ‘cause’ of mental disorders within the body,
rather than acknowledging that social and environmental factors are
the main causes of trauma, distress, and psychological
