Critical Stimulus is a psychoanalytical tool based on the word association experiments by psychologist Carl G. Jung. It uncovers unconscious fears, hidden agendas, guilt, unresolved personal issues and more. If there is an emotional-psychological disturbance exerting invisible control over your life, Critical Stimulus will shine a spotlight on it. Available as a physical card deck (100 cards and instruction book) or download the PDF with cut-out cards. Note: Although Critical Stimulus deals with the psyche and unconscious processes we do not fully understand, it is in no way “mystical” or magical. It is a psychoanalytical tool founded on decades of rigorous scientific studies.
