The Subjectivity of emphasis Groups and Ink Blot test

Companies require to understand how world see your products and what lock want, so asking customers around this in a focus group seems prefer a good idea. Emphasis groups can provide a valuable type of qualitative research, providing companies understanding into consumers’ beliefs, desires, and attitudes bordering a product. However, while focus groups can carry out some insight, the history of projective test (aka squid blot tests) in psychology offer a cautionary story on solely relying ~ above this kind of self-reported qualitative data.

You are watching: What is one criticism of projective tests?

Beginning in the at an early stage 20th century psychologists and also psychiatrists emerged projective tests come diagnose psychological disorders and gain access to patients’ unconscious beliefs and also desires. These tests, based on Freud’s theory of projection, were assumed to enable unconscious beliefs and also desires to surface through their open-ended structure, i beg your pardon was believed to be much less threatening come people. In a projective test, who is shown a collection of ambiguous or abstract pictures that can be interpreted in countless ways (the most famous instance is the Rorschach octopus blots, generally portrayed in emotional examinations in movies), and they space asked to talk about what lock see and also what the photos make castle think of. That was believed that human being will project their subconscious think (desires, beliefs, etc.) ~ above the image, thereby revealing covert parts of their personality that can then it is in analyzed and also interpreted through the psychiatrist administering the test.

Projective tests to be heralded together a breakthrough diagnostic tool, until they came under scrutiny in the 1980s and also 90s, together psychoanalytic theory fell out of favor. The difficulty with projective test is the they absence validity and reliability, the two vital aspects of any psychological assessment. Reliability refers to how continual the outcomes of a offered test are: a test that is trusted will yield the same results time and also time again. Validity describes whether other actually measures what it claims to it is in measuring. Projective tests are unreliable for 2 reasons. First, the is unclear whether what human being say actually mirrors anything meaningful around their psyche. Periodically it might, frequently it doesn’t, and it is frequently impossible to tell the difference. Second, even if someone’s responses perform reflect other meaningful, the results are subject to the interpretation of the examiner. Study on projective exam has displayed that interpretations of the exact same data vary widely, and thus these tests yield various results depending upon who is interpreting them. A test cannot be precious if the is not dependable (reliability is a necessary, but not sufficient problem for validity), but validity is additional compromised because it no clear what subjects’ reports actually also reveal around their psyche. Because that these reasons, major clinicians no much longer use projective tests because that diagnosis, but only as icebreakers to acquire a conversation started.

In plenty of ways, emphasis groups resemble projective tests. Human being are inquiry to connect with something they’ve often never checked out before and also comment on the in some method (akin come the function of a patient in a projective test). Then one or an ext observers translate their responses (akin to the role of the psychiatrist in a projective test). Focus groups endure from the same problems with reliability and validity together projective tests. Due to the fact that people are frequently unaware of an important aspects that their own minds, that is tough to phone call whether their reports truly reflect coherent insights right into their decision-making. Furthermore, the interpretation of the outcomes crucially depends on who doing the interpreting. Together anyone who has operated with emphasis groups knows, the translate of the results frequently varies widely across observers, together observers’ very own agendas and also beliefs space inevitably integrated into what lock think people’s reports mean. Forecast is a two means street, and also often observers’ conclusions reveal an ext about their very own biases than about what the respondents in reality said.

This is no to to speak that emphasis groups provide no value, also such subjective qualitative data is much better than no data, however it should be clear the information gathered and analyzed from emphasis groups need to be taken through a serial of salt. They have the right to provide an excellent icebreakers, and help inform how people might think about a product, however it is hard to recognize whether their results are valid, or their conclusions room reliable. In ours opinion any type of such results must be shown by additional research making use of objective, quantitative methods, with well-known validity and also reliability.
