Why is it important?
Although there are decades of research questioning the assumption that the human mind can be measured, the bulk of psychology still relies on alleged measurements. Furthermore, many psychological instruments that are widely used in public (e.g., intelligence tests) are also based on the measurement assumption. Since there are many reasons to be sceptical about psychological measurement, it is important to show how psychological reserach can be freed from contested assumptions about psychological measurement. This can help in making psychological research more defensible.
