Diagnosis and therapy of psychology by means of systematicity theory

In the last decade there have been intense disputes about the scientific status of psychology espe-cially in connection with the replicability of prominent effects in textbooks. Very different statements about the reasons for this situation have been given (for instance, sample sizes too small, inferential statistical considerations, faulty applications of evaluation methods, lack of theory building, etc.). All these reasons have their relative justification. What remains unresolved, however, is whether these deficiencies are really the fundamental reasons for the state of psychology as a science or just sur-face symptoms. Thus, one needs a diagnosis that can identify these fundamental reasons. For this purpose, the systematicity theory is suitable, which can address the scientific status of psychology, e.g., in distinction to everyday psychology, via nine aspects. These nine aspects are well founded and at the same time can give hints how to improve the scientific status of psychology. Only by advancing a common and integrated development of psychology will it be possible to improve its scientific sta-tus. Individual improvements of rather arbitrarily selected aspects cannot achieve that. The purpose-ful connection of diagnosis and therapy will be demonstrated by the example of psychology in order to guide the scientific process in a focused way
