What if healing your sibling relationship could change every other relationship in your life?

If you’ve ever felt trapped in sibling patterns that keep repeating—walking on eggshells, replaying old fights, or wondering if peace is even possible—this book is for you.

I’m Right, You’re Stupid: Growing Up Your Sibling Relationship is your roadmap from conflict to connection. It helps you understand the roots of sibling tension, calm the emotional triggers that keep you stuck in that pattern, and practice a new way of relating—one rooted in curiosity, accountability, and respect.

After decades of discord and disconnection, sisters Jessica Marriott and Dr. Bluma Sapir set out to heal their own relationship. What began as a private reckoning became a research-backed framework for transforming sibling dynamics everywhere—and inspired the award-winning documentary Roots Tour: A Sibling Journey from Hatred to Harmony.
