Reliable findings are a cornerstone of scientific research, and emerging subfields in psychology and neuroscience often suffer large corrections1,2 due to unreliable findings. Therefore, examining the reliability of methods in new subfields such as computational psychiatry is very important. However, investigations into reliability have a catch. Because reliability is a measure of stability (in the case of test–retest reliability, stability over multiple assessments), any source of noise corrupts measurement and lowers reliability. Measures do not have good or bad reliability; rather, a specific measure, assessed using specific procedures in a specific population, and analyzed using specific methods, has good or bad reliability. Establishing the reliability—or lack thereof—of a measure depends on this context. When claims are made about the reliability of a class of measures, therefore, they need to take the methodological context into account. Additionally, incorporating up-to-date research methods is needed to eliminate known sources of noise and increase generalizability.
