In 1980, after six years inside Columbia, Spitzer felt ready to publish. But first he wanted to road test his new checklists. And there were a lot. DSM-I had been a sixty-five-page booklet. DSM-II was a little longer—134 pages. But DSM-III, Spitzer’s DSM, was coming in at 494 pages. He turned the checklists into interview questionnaires and sent researchers out into America to ask hundreds of thousands of people at random how they felt.
