Ink blot test

Ink blots inspired artists such as Leonardo da Vinci and Victor Hugo in the 15th and 19th centuries.[7] Alfred Binet also suggested using ink blots to assess visual imagination.[8] Although the Rorschach test was widely used, its popularity died down because controversy over the validity of the test measurements. Hermann Rorschach never intended for the ink blot to be a sole assessment of personality, however some psychologists may have tried to use it as such. Many people thought the measurement of responses were too subjective which led psychologists to come up with a better way of measuring responses after Rorschach's death. For example, Holtzman inkblot technique was seen as less controversial, because the developers took previous criticism into consideration and aimed to make their test better. Another variation of the Rorschach test is the Howard Ink Blot Test. This test was aimed at group measurements of personality rather than an individual measurement.[9] While these tests were seen to have improved validity of ink blot tests, psychologists are still skeptical which lead to the fallout of these projective tests.

The procedure for administration and measurement varies by each ink test, however, they are all based around how the participant responds to ambiguous stimuli. The Howard ink blot test for example, has participants responding to one card at a time with the ink blots on it. They are then told to tell the psychologist everything they see and what it might represent to them. Time of responses from start to finish is also measured with this test.[10] For the Rorschach test, subjects are sitting side by side with the researcher and is presented with the 10 official ink blot cards one at a time. After they have all been presented once, and the participant has responded, the cards are presented again and the participant is told to rearrange the cards to match what they saw the first time. The researchers watching monitor every movement and everything the participant says aloud as well and records it.[11] This is a lot different from the Howard test because the cards are re-presented to the participants. Tests like the Blacky pictures test and the Thematic apperception test involve making up narratives for the pictures presented to the participants. Based on these narratives, psychologists can assess personality and unconscious thoughts and motives. While all these projective tests have different procedures and types of measurement, they are all thought to measure one's personality, one's thoughts and one's emotions; including those that are from the unconscious mind of the participant. Dr. Rakesh Kumar wrote a book Rorschach Inkblot Test: A Guide to Modified Scoring System, which is his interpretation on how to administer, score, and diagnose based on the ink blot tests.

These tests were developed to be used in clinical, organizational, and human resource departments.[12] Some psychologists might still use these tests today for personality assessments or assessments of unconscious motives or feelings. However, the American Psychological Association discourages use of official ink blot tests.[13] Because of the early and untimely death of both of these men, resulting in the lack of a key to reading the answers given by patients, psychologists have been skeptical of using the ink blots as a reliable source in clinical work. Many studies have been conducted trying to deduce an answer to whether or not to use the ink blots. An overview of past ink blot studies, found that the ink blots do show a tendency towards certain data but there is a lack of research and evidence actually using the ink blots clinically.

Psychologists who use projective tests, like the ink blot test, argue that they are useful at tapping into underlying thoughts and desires that not even the patient is aware that they are having.[14] Since a projective test requires a highly trained psychologist to analyze the data and determine what it means, it has faced criticism. Projective tests, such as the Rorschach test have been criticized due to issues with inter-rater reliability, test-retest reliability (repeatability), validity, biases, and issues with cultural sensitivity and norms.[15]

One advantage of projective tests is that individuals taking the test are free to answer however they see fit. Since projective tests are subjective, participants don't have any constraints on how they answer. The subjectivity of these tests is why psychologists thought that it measured one's most inner thoughts and feelings and/or ones personality. The more unstructured stimuli, the more the participant reveals about themselves.[16] This contrasts with objective tests where the answers are clearly put into categories and participants are very limited in how they can answer. While objective tests can still measure emotions, thoughts, and personality, the answers are already pre-set thereby limiting the answers of the participant. This in theory, would hinder the process of stating one's most inner thoughts & feelings. Another advantage is the ambiguity of the projective tests makes the purpose of the test unknown. This is an advantage because if participants know what they are being tested for, they are more likely to socially conform and mask their true answers.[17]
