Question: The book What's Wrong with the Rorschach: Science Confronts the Controversial Inkblot Test (Wood et al., 2003) presents an overview of scientific evidence that suggests the Rorschach test performs poorly at diagnosing psychopathology, determining personality traits, and predicting future behavior. For example, the Rorschach tends to overdiagnose, labeling many people without psychopathology as sick.
a. Do these findings relate more to reliability or validity? Explain.
b. Explain how a test such as the Rorschach could be reliable, even if it were not valid.
