These tests were developed to be used in clinical, organizational, and human resource departments. 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<unk> s. 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<unk> <unk> s as a reliable source in clinical work. Many studies have been conducted trying to deduce an answer to whether or not to use the<unk> <unk> s. An overview of past<unk> <unk>  studies, found that the<unk> <unk> s do show a tendency towards certain data but there is a lack of research and evidence actually using the<unk> <unk> s clinically. Psychologists who use projective tests, like the<unk> , argue that they are useful at tapping into underlying thoughts and desires that not even the patient is aware that they are having. A projective test requires a highly trained psychologist to analyze the data and determine what it means, this would leave room for 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. 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. 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.
