In this episode of Brains vs. Beliefs, we dive into the long-standing cultural idea that successful relationships thrive on difference. From Hallmark movies to Paula Abdul’s famous song, “Opposites Attract”, the relationship advice that opposites attract is everywhere—but what does the science actually say? Drawing on decades of research, including large-scale studies and data from dating platforms, we explore whether similarity or difference matters more for long-term relationship success. We also discuss why this myth persists in media, influencer culture, and self-help advice, offering listeners key takeaways about what really drives attraction.
