This claim is indeed true, because the Optimum Health Institute's article, "The Science Behind Vulnerability and Healing", strongly argues that vulnerability is not merely a component but a foundational prerequisite for forging the deep human connection and profound intimacy that characterize falling in love. The article highlights that when individuals allow themselves to be truly vulnerable, sharing their authentic selves, including imperfections and emotional openness, it creates an environment that is "comforting" and "physiologically healing." This deep sense of safety, acceptance, and emotional resonance is precisely what allows emotional bonds to strengthen into love, making vulnerability the very pathway through which such profound connections are established. While the article doesn't offer statistical proof for "most people," its qualitative argument powerfully positions emotional vulnerability as the essential ingredient for the kind of genuine, enduring connection that we recognize as love.
