Schizophrenia
This may seem to show that schizophrenia is inherited. However, it may be the stress of living with a schizophrenic family member that is traumatic. Identical twins are much closer and are treated much more in the same way, and this may be the reason why one of them is more likely to get schizophrenia if the other has it. Dr Jay Joseph has found many problems with the scientific studies of inheriting schizophrenia, including false reporting of results. Joseph also claims that 40 years of the search for the schizophrenia gene has not found a single gene that independent research groups have confirmed.
