The Science of Infidelity (research)

The science of infidelity examines why individuals cheat in relationships, focusing on biological, psychological, and social factors. Research suggests biological influences include hormonal and neural responses that affect attraction and attachment. Psychological aspects involve personal dissatisfaction, unmet emotional needs, or traits like impulsivity. Social factors encompass cultural norms, opportunity, and relationship dynamics. Studies also explore how brain activity related to reward and decision-making may predispose some to infidelity. Understanding these factors helps clarify that cheating is often driven by complex, multifaceted influences rather than solely moral failure, highlighting the importance of emotional health and communication in maintaining trust and fidelity.
