The psy­cho­log­i­cal mea­sure that proves to be Starkwell’s undoing—rejected, he turns to a life of crime—is the Rorschach inkblot test, devised a cen­tu­ry ago by Carl Jung’s com­pa­tri­ot and fel­low psy­chol­o­gist, Her­mann Rorschach. Although Rorschach would die young, at 37, his name­sake remains embed­ded in our per­cep­tion of psy­chol­o­gy, along­side Freud’s couch and Pavlov’s dog. Whether the young Rorschach had innate artis­tic lean­ings, or had begun to lis­ten to his father more close­ly after the death of his moth­er at age 12, is uncer­tain. Even before the young Rorschach began to study psy­chol­o­gy, the med­ical pro­fes­sion had flirt­ed with imagery asso­ci­a­tion. After notic­ing that schiz­o­phrenic patients asso­ci­at­ed vast­ly dif­fer­ent things with inkblots than oth­er patients, Rorschach, fol­low­ing some exper­i­men­ta­tion, cre­at­ed the first ver­sion of the inkblot test as a mea­sure of schiz­o­phre­nia in 1921.
