Hermann Rorschach

Introduction

Hermann Rorschach (8 November 1884 – 1 or 2 April 1922) was a Swiss psychiatrist and psychoanalyst who developed the inkblot test that carries his name. Trained in the Zurich clinic of Eugen Bleuler and an early advocate of psychoanalysis in German-speaking Switzerland, he spent his career in cantonal asylums rather than universities, and he died at thirty-seven of peritonitis from an appendix diagnosed too late. The test he published in 1921 as Psychodiagnostik became the most famous instrument in personality assessment and one of the most contested. Rorschach himself described it as a method of form interpretation that measured perception, intelligence, and affective characteristics; the idea that it is a projective window onto the unconscious was attached to it by others, after his death.

Early Life and Education

Rorschach was born in Zurich and grew up in Schaffhausen, where his father, Ulrich Rorschach, taught art. He was the eldest of three children; his mother died when he was twelve, and his father followed after a long illness seven years later. At the Schaffhausen cantonal school his classmates called him Klecks, inkblot, after the fashionable pastime of Klecksography, making fanciful symmetrical pictures from blots of ink. Unlike his classmates he eventually made inkblots his life's work.

Unable to choose between art and science at graduation, he wrote to the German biologist Ernst Haeckel for advice; Haeckel suggested science. Rorschach spent a semester at the Académie de Neuchâtel studying geology and botany and took a French course at the Université de Dijon before enrolling in medicine at the University of Zurich in the autumn of 1904. He decided to specialise in psychiatry at twenty-two. His studies took him to Berlin for the winter semester of 1906–1907, from where he travelled to Russia for the first time, and to the University of Bern for a semester, before he graduated at Zurich in the spring of 1909. He took up a post as resident physician at the cantonal psychiatric hospital in Münsterlingen and, in 1910, married a fellow medical student, Olga Stempelin, from Kazan.

Two teachers mattered most. He heard Eugen Bleuler on general and special psychiatry and on clinical psychiatry, and he attended Carl Jung's lectures on the psychopathology of hysteria. Bleuler supervised his doctoral dissertation, Über Reflexhalluzinationen und verwandte Erscheinungen (On Reflex Hallucinations and Related Phenomena), published in 1912. For years his principal intellectual interest was psychoanalysis, and he became one of its earliest defenders inside Swiss medical circles.

Academic and Professional Career

Rorschach left Münsterlingen in April 1913 and spent a few months at the psychiatric clinic in Münsingen near Bern. At the end of that year the couple went to Russia, where he took a well-paid position at the fashionable Krjukovo sanatorium outside Moscow. The attempt to establish themselves as a pair of doctors in Russia failed; in the summer of 1914 he returned to Switzerland and accepted a poorly paid post as assistant doctor at the Waldau psychiatric hospital near Bern.

In the autumn of 1915 he moved again, becoming associate director of the Appenzell Ausserrhoden psychiatric hospital in Herisau on 1 November, a post he held until his death. Colleagues knew him as a meticulous clinician who drew unusually detailed charts of his patients. In 1919 he was elected vice-president of the Swiss Society for Psychoanalysis.

The inkblot work began from a discovery rather than a theory. In 1917 Rorschach came across the work of Szymon Hens, who had used inkblot cards to study imagination, and a year later he began his own experiments with fifteen blots. He showed them to schoolchildren and to patients, and noticed that people diagnosed with schizophrenia responded differently from other groups. By the time he wrote Psychodiagnostik, published in the spring of 1921, he had tested more than three hundred psychiatric patients and about a hundred people he took to be normal. The book was initially ignored, then drew attention precisely because it attracted criticism.

Rorschach died at Herisau on 1 or 2 April 1922, aged thirty-seven, leaving a widow and two small children.

Major Contributions to Psychology

Form interpretation, not projection

Rorschach's own account of the method was perceptual. He called it Formdeutung, form interpretation, and argued that the way a person organises an ambiguous visual field reveals how they perceive, how intelligent they are, and what their affective character is like. Scoring sorted each response by content, by the location on the card the response referred to, and by determinants such as form, colour, and shading. From those proportions he derived an Erlebnistypus, an experience type describing whether a person was turned inward or outward, and he used the measure to separate diagnostic groups. The term projective test did not exist in his vocabulary: it was coined by Lawrence K. Frank in 1939, seventeen years after Rorschach's death.

The plates

Rorschach tested more than forty blots before settling on his set, and commercial constraints meant that only ten were printed in the book: five in black and grey, five in colour. The plates were made by dropping ink on paper and folding it, so that the blot spread symmetrically across both halves. Rorschach selected from thousands for the ones that met his conditions. He was not the first to use blots: Justinus Kerner had published a book of poems inspired by accidental inkblots in 1857, Alfred Binet had experimented with them as a test of creativity, and Hens had preceded him directly. What Rorschach added was a scoring system and a standardised set of cards.

Impact and Legacy

The test became a fixture of clinical training and court-ordered evaluation, and its cultural afterlife, from Watchmen to the phrase reading the inkblots, has outlasted most of psychology's instruments. It also became the standard example in textbooks of how a measure can be famous and disputed at the same time, and it sits inside a longer history of psychology in which perception-based assessment competed with self-report.

The criticisms are unusually well documented. The first concerned reliability. After Rorschach's death five rival scoring systems grew up around the plates, associated with Samuel Beck, Bruno Klopfer, Marguerite Hertz, Zygmunt Piotrowski, and the team of David Rapaport and Roy Schafer. They coded the same response differently and sometimes contradictorily, so two clinicians could reach opposite conclusions from one protocol. John Exner's Comprehensive System, published from 1974, unified administration, scoring, and interpretation; under trained scorers inter-rater agreement now runs around .88 to .90, and that part of the debate is largely settled.

Validity is not settled. Mihura, Meyer, Dumitrascu, and Bombel reviewed fifty-three meta-analyses covering sixty-five Comprehensive System variables in 2013 and found average validities of r = .27 against criteria such as clinician ratings and diagnosis but only r = .08 against self-report. About forty of the sixty-five scores showed modest-to-good support; the rest had little or none. Notably, the strongest variables were the thought-disorder indices tied to what Rorschach originally built the test to detect. Wood, Garb, Nezworski, Lilienfeld, and Duke replied in 2015, adding unpublished studies to counter publication bias, and concluded that several widely used indices had weaker support than proponents claimed, with no evidence linking the system's indexes to non-cognitive characteristics such as negative affect. Mihura and colleagues then reported coding and data errors in that reanalysis.

A second line of attack concerns the norms. Lilienfeld, Wood, and Garb and their collaborators found that American adults living in the community score in the maladjusted range when Exner's norms are used, which makes healthy people look pathological; exaggerated rates are reported for lower socio-economic groups and for children, and black, Hispanic, and Native American respondents score differently from white Americans on several variables. Exner's defenders reply with the international collaborative study of 4,704 protocols across seventeen countries, in which only 2 per cent showed significant elevation on the perceptual and thinking disorder index, in line with expected base rates.

The third concerns what the test adds. Incremental validity is generally poor: most Comprehensive System scores do not supply information beyond what cheaper self-report instruments already give. The test has repeatedly failed as a predictor of impulsiveness, criminal behaviour, violence, or child sexual abuse, and claims that references to buttocks, anuses, feminine clothing, or sex organs in a response predict homosexuality have never had any empirical support. Chapman and Chapman showed in 1969 why such beliefs persist: clinicians confidently used signs that carried no diagnostic information, and naive students shown fabricated protocols in which those signs were deliberately uncorrelated still discovered the same invalid associations.

Legally, the record is mixed rather than one-sided. Lilienfeld and Grove argued the Comprehensive System fails the Daubert standard, citing erroneous norms, questionable reliability, unresolved validity, and the fact that Exner's own data were largely unavailable for scrutiny. Courts have agreed in places: Jones v. Apfel held in 1997 that Rorschach results do not meet the requirements of standardization, reliability, or validity, and United States v. Battle ruled in 2001 that the test has no objective scoring system. Against that, in some eight thousand cases in which forensic psychologists offered Rorschach-based testimony, the instrument's appropriateness was challenged only six times and the testimony ruled inadmissible once.
