#Infidelity

A recent study into the psychology of infidelity is prompting renewed debate among Thai readers about whether the old adage, “once a cheater, always a cheater,” stands up to scientific scrutiny. According to coverage by Psychology Today, fresh research examines how likely it is that someone who has cheated once will commit infidelity again in future relationships—a question at the heart of many relationship anxieties both in Thailand and worldwide.

The topic of infidelity remains particularly salient in Thai society, where rapid modernization and digital communication have brought new complexities to romantic relationships. Historically, Thai culture has valued harmony, discretion, and family cohesion, but changing social norms and greater gender equality have put issues surrounding monogamy and fidelity under sharper scrutiny. Relationship experts in Thailand note that suspicions or experiences of betrayal often carry heavy cultural stigma, impacting not just personal well-being but extended family dynamics as well.
