The Gottman Institute stands as the gold standard in relationship science, built on Dr. John Gottman's four decades of research with thousands of couples. Their evidence-based approach to understanding what makes relationships succeed or fail has revolutionized couples therapy worldwide. The site offers exceptional resources including workshops, therapist training, books, and their popular assessment tools. Their concepts like the 'Four Horsemen' and 'Love Maps' have become essential vocabulary in relationship counseling. While their sexual intimacy content is solid, it's less comprehensive than their communication and conflict resolution materials. Premium content and workshops can be pricey, but the research-backed methodology justifies the investment for those serious about relationship improvement.
