John Gottman's book, The Science of Trust, focuses on the dynamics of trust and betrayal in romantic relationships.

Gottman uses longitudinal studies and game theory to develop a "trust metric" that mathematically measures trust within interactions. He examines factors predicting relationship success or failure, including communication patterns, emotional responses, and physiological arousal.

Furthermore, Gottman explores the role of oxytocin and other hormones in shaping trust and the physiological consequences of betrayal.
