Quizplus · Accepted Answer

Exner's system improved the interpretation of Rorschach inkblot responses by increasing inter-rater reliability and reducing subjectivity among clinicians. This greater agreement among clinicians helped to increase the validity and reliability of the Rorschach test as a tool for assessing personality and identifying psychological disorders. Exner's system also introduced more detailed scoring criteria and a standardized administration protocol, which further improved the test's reliability and validity. However, Exner's system did not introduce a larger number or variety of inkblots, nor did it aim to align with the Big Five model of personality.
