The Compatibility Trap

In The Compatibility Trap, psychologist Dr. Sanna Balsari upends everything you thought you knew about love, revealing that chasing the 'perfect fit' can hold us back from lasting and fulfilling relationships.

There’s a golden rule in modern dating: compatibility is the key to happiness. We take tests, compare traits, and search endlessly for our perfect match—for that someone who “completes us.” But what if this obsession with compatibility is doing more harm than good?

In The Compatibility Trap, Cambridge PhD psychologist and professor Dr. Sanna Balsari makes the persuasive case that we’ve been going about love all wrong. She draws on psychological research and real-life examples to persuasively show why compatibility simply is not the be-all-end-all we’ve made it out to be. While some degree of ‘fit’ in a relationship is necessary, lasting relationships are forged in the harder, more rewarding work of embracing friction.

Drawing on her own dramatic search for her ‘most compatible match’, Dr Sanna Balsari reveals that our misunderstanding of compatibility says less about love itself and more about our cultural discomfort with differences. Dr. Balsari-Palsule places compatibility in its broader historical and social context, and dismantles the myths that continue to shape how we choose our partners and evaluate our relationships. She then introduces a practical framework for working with differences that emerge in a relationship using three categories:

• Low stakes differences (the minor mismatches that can grate, annoy, or trigger the “ick”)
• High-stakes differences (the more significant tensions that require real work to navigate)
• Deal breakers (fundamental differences in values)

Across lifestyle clashes, politics, financial differences, sexual chemistry, and the spectrum of orange, red, and green flags in between, she offers strategies for transforming areas of friction and potential conflict into areas for deeper connection and meaningful growth.

Dr. Balsari weaves together the latest scientific studies with entertaining, heartfelt, and sometimes hilarious stories from her own dating life, as well as conversations with a range of couples and individuals that navigate the same messy reality that all of us face. She also provides hands-on tools, exercises, and self-assessments to help readers put these ideas into practice. Whether you’re in the dating app world, a situationship, or a long-term marriage, The Compatibility Trap is an empathetic and engaging roadmap to empower you to build, rather than find, a love that lasts.

Insightful, surprising, and provocative, The Compatibility Trap is Dr Sanna Balsari's no-nonsense blueprint to forever change how you approach intimacy, connection and love.
