I will first admit that I know little about the empirical background of the Rorschach but I noticed reading the discussion within the Wiki that it does not seem like there is consensus that it is not a valid measure. One of the discussion comments said there have been metanalyses done on the test but I could not find anything recent in a lit search. The wiki article said that the Rorschach is good at detecting certain things such as schizophrenia but it seems like when it was first developed people were a little grandiose in what they thought it could accurately assess. With the new rating scales and such is it still an unreliable measure for all psychological constructs?

An interesting thing about the Rorschach is that it is so dependent on the stimuli being novel to the test taker in order to be reliable that the popularization of the test in the culture might actually harm the validity. Apparently the wiki page contains actual items from the test and a lot of people are upset about this. While I agree with you to the extent that the Rorschach is unreliable for assessing certain things (such as cancer, as noted in the article), I still think it has usefulness for other things such as personality disorders (or apparently intelligence). Do you have any citations for why it is not a valid measure specifically and for which constructs/pathologies? Have you used the Rorschach (I have not personally, but I am just a lowly grad student)? Because this is r/neuroscience, what is the relevance of this article as applied to neuroscience? This might be better received in r/AcademicPsychology.
