The Science of Opening Up: The Hidden Cost of Under Sharing | Dr. Leslie John - EP 737
from Passion Struck with John R. Miles · host Passion Struck with John R. Miles
Why do we feel a "disclosure hangover" the moment we reveal something real, yet feel a persistent sense of loneliness when we stay silent?Today, we are diving into the complex psychology of human connection with one of the world's leading experts on the science of secrets and sharing. Joining me is Harvard Business School professor and author Dr. Leslie John to discuss her groundbreaking new book, "Revealing."In this conversation, we challenge the conventional wisdom that "less is more." Leslie argues that while we are hyper-aware of the risks of oversharing (TMI), we are almost entirely blind to the devastating costs of under-sharing (TLI—Too Little Information). We explore why silence is not neutral and how the fear of vulnerability is actually holding us back from the trust, influence, and well-being we crave.We move from the research labs of Harvard to the internal "release valves" of our own emotions. Leslie reveals why your "disclosure reflex" might be miscalibrated and how "revealing wisely" can supercharge your career, deepen your most important relationships, and even improve your physical health.If you’ve ever held back your truest self out of fear of judgment, this episode provides the scientific compass to help you navigate the social risks of being real.Passion Struck is the #1 alternative health and personal growth podcast dedicated to human flourishing and the science of mattering.
