The principal goal of psychological science is not application but theory. This is because a good theory yields accurate predictions and control, two preconditions for applications. Thus, good psychological science is one that produces good theories. Against the background of reproducibility crisis and the apparent non-existence of an integrated subfield of psychology addressing those issues, I submit psychological theoretics (or psycho-theoretics) as a potential solution. The scope of psychological theoretics is outlined and distinguished from other closely related subfields. It was argued that psychological theoretics has the potential to make a unique contribution to the advancement of good psychological science. It is also worth noting that even if the global community of psychologists might not be ready for psychological theoretics as a new subfield, the reforms proposed under its rubrics would still remain relevant today and in the future. Indeed, the question of whether it is completely new will surely be the subject of scientific debate.
