This paper examines the proposed asymmetry that should occur between resonance and dissonance in physician–patient relationships in favour of resonance to facilitate an effective relationship. Resonance is represented by the positive emotional attractor, which comprises patients’ conscious preferred future or ideal self, and dissonance is expressed by the negative emotional attractor and consists of the gaps between patients’ ideal and real self or their fears, problems, and shortfalls. Intentional change theory is reviewed to optimise the physician–patient relationship. Concepts from complexity theory and recent research on emotions are used to explain positive and negative emotional attractors. The role of resonance and dissonance in physician–patient relationships is discussed along with how behaviour can be changed with positive and negative emotional attractors. This paper focuses on the quality and effectiveness of physician–patient relationships for physicians who create high versus low positive emotional attractor/negative emotional attractor ratios. Two theoretical propositions are offered and the research and practice implications are explained.
