Redefining the Methodology of Psychology and Psychoanalysis Through the Principle of Qualia Inaccessibility

This paper applies the “Principle of Qualia Inaccessibility”—the claim that subjective experience (qualia) cannot be observed or proven as an object by a third party—to the methodology of psychology and psychoanalysis, proposing a fundamental re-evaluation. Psychology and psychoanalysis have traditionally relied on methods that objectify the inner world of patients or subjects, extracting universal structures from verbal reports and behavioral observations. However, if objective qualia are, in principle, unobservable, such methodologies possess inherent foundational limits. This is not a critique of theoretical content, but an invalidation of the very preconditions for theory formation, constituting a potential paradigm shift in the history of psychology.
