The Sibling Effect: What the Bonds Among Brothers and Sisters Reveal about us Jeffrey Kluger Nobody affects us as deeply as our brothers and sisters do - not parents, not our children, not our friends. Siblings are our collaborators and co-conspirators, our role models and cautionary tales. They teach us how to resolve conflicts and how not to, how to conduct friendships and when to walk away. Our siblings are the only people we know who truly qualify as partners for life, and our connections to them last a lifetime. In this groundbreaking book, renowned science writer Jeffrey Kluger explores the complex world of siblings in a way that is equal parts science, psychology, sociology, and memoir. The Sibling Effect delves into the impact of birth order and genes, of favoritism and broken homes, of competitiveness, gender, sexuality, and more. All of this influences our relationships with our brothers and sisters, and those relationships, in turn, shape the people we become. Kluger takes science's provocative new ideas about siblings and transforms them into smart, accessible insights that will help all of us understand the importance of siblings in our lives.
