I’d also like to add, and hope you won’t mind my doing so, that according to Haefner
“[a]t present, it can neither be proven nor disproven by
reliable data whether the compulsory sterilization of persons
suffering from schizophrenia, supposedly a congenital
disease, and the mass killing of people with
schizophrenia in the Nazi era considerably reduced the
risk for schizophrenia in the next generation.”
Thanks for a very interesting post!
