Twin studies

This guy reminds me of Judith Harris. I wonder if it's still true.
"In graduate school at UC [the University of California] Berkeley, I was reading a book edited by psychiatrist D. D. Jackson on the etiology of schizophrenia. The first chapter, by a geneticist, was on twin studies. Then Jackson refuted it all with just the kind of [guff] you hear now against twin studies. He said families are the cause of schizophrenia. I remember saying in a graduate seminar, "Most of this stuff [in Jackson's argument] is junk"—I crawled out of the seminar room a bloody pulp. The reaction [from seminar members] was my first absolutely clear-cut demonstration that psychologists believed correlation is causation, ... and many still do."

Rock Is Dead. Long Live Scissors!

"The presentation or 'gift' of the Holy Ghost simply confers upon a man the right to receive at any time, when he is worthy of it and desires it, the power and light of truth of the Holy Ghost, although he may often be left to his own spirit and judgment." --Joseph F. Smith (manual, p. 69)
