His education in art helped to spur the development of a set of inkblots that were used experimentally to measure various unconscious parts of the subject's personality.

His method has come to be referred to as the Rorschach test, iterations of which have continued to be used over the years to help identify personality, psychotic, and neurological disorders.

For example, in 1857, German doctor Justinus Kerner had published a popular book of poems, each of which was inspired by an accidental inkblot.

After Ernst Haeckel suggested a career in science, Rorschach attended Académie de Neuchâtel in 1904 studying geology and botany.

Torn by the decision of whether to stay in Switzerland or move to Russia, he eventually took a job as first assistant at a Cantonal Mental Hospital.

While working at the hospital, Rorschach finished his doctoral dissertation in 1912 under the psychiatrist Eugen Bleuler, who had taught Carl Jung.

[2] In 1915, Rorschach took the position of assistant director at the regional psychiatric hospital at Herisau,[6] and in 1921 he wrote his book Psychodiagnostik, which was to form the basis of the inkblot test.

[2] Rorschach graduated in medicine at Zurich in 1909 and at the same time became engaged to Olga Stempelin, a girl from Kazan (in the present-day Russia).

Unlike descriptions of inkblots and their characterizations, this instantiation of the Rorschach concept is numerically/topologically analysable, with neural nets and latent space geometries capable of predicting preference to as much as 90% accuracy.
