# The Underrated Power of Oversharing | Leslie John Source: https://www.youtube.com/watch?v=klAT_uknwNU Recap page: https://rapidrecap.app/video/klAT_uknwNU Generated: 2026-03-02T10:32:38.334+00:00 --- ## Quick Overview Self-disclosure is intrinsically rewarding, activating the brain's pleasure centers similarly to sex, and going one level deeper than expected in communication builds trust, contrary to the common fear that oversharing leads to negative outcomes. **Key Points:** - Self-disclosure activates the pleasure centers of the brain, showing it is intrinsically rewarding, with activation levels comparable to those experienced during sex. - People prefer a suitor who admits to having had many STDs over one who refuses to answer the question, and 89% prefer hiring an applicant who admitted to bad grades over one who opted out of answering. - Holding back or hiding information leads to distrust and contempt from others; the person who doesn't reveal is distrusted relative to the revealer. - The risks of revealing are often overestimated due to impact bias, while the costs of keeping quiet, such as rumination, mental load, and even temporary IQ decreases, are ignored. - Transforming swirling thoughts and feelings into language, either by writing or speaking, engages the prefrontal cortex, imposing structure and logic that reduces anxiety caused by uncertainty. - The guideline for better communication is to 'go one level deeper than you might think you should,' moving from commenting on events to commenting on the meaning of those events to you. - When revealing sensitive information, validation, exemplified by the phrase 'that sucks,' is the most soothing response listeners can offer, even more so than bright siding or perspective-taking. **Context:** The interview features Dan Harris speaking with researcher Leslie John about the underrated power of self-disclosure, often mislabeled as oversharing. Leslie John's research journey began with studying online oversharing mistakes but evolved due to a personal disconnect where she experienced the joy of disclosure while professionally cautioning against it, leading her to investigate the significant upsides of revealing personal information. ## Detailed Analysis Leslie John argues that what feels like over-communicating is often just necessary communication, and people should push one level deeper in disclosure because the line for comfort is further out than commonly perceived. Her research highlights that withholding information causes distrust; for instance, people prefer dating or hiring someone who admits to negative facts over someone who refuses to answer sensitive questions. This preference stems from the idea that opening up relinquishes control, implicitly signaling trust, which in turn builds reciprocal trust. Neuroscience studies confirm that self-disclosure activates pleasure centers in the brain, suggesting it is fundamentally motivating, while studies on preschoolers show that expressive children exhibit less physiological stress than those who learn to be stoic. John emphasizes that not speaking one's mind has consequences, including rumination and decreased well-being, noting that keeping a simple secret can temporarily lower IQ. Conversely, articulating feelings, even just to oneself in writing, engages the logical prefrontal cortex and imposes narrative structure, reducing anxiety. When sharing with others, validation, like saying 'that sucks,' is the most potent tool for increasing well-being, surpassing attempts at bright siding or perspective-taking. Skilled communicators possess 'disclosure flexibility,' knowing when to be extremely open (e.g., with a life partner) versus extremely reserved (e.g., in a competitive negotiation), guided by interrogating their goal for the interaction, such as venting, seeking support, or acting as a 'catalyst confession' to spur change. ### The Rewards of Disclosure - Self-disclosure is intrinsically rewarding, activating pleasure centers similar to sex - Disclosure builds trust because relinquishing control implicitly signals trust in the listener - Studies show people prefer revealing partners/hires over silent ones, viewing silence with contempt. ### The Hidden Costs of Under-sharing - Not speaking up leads to rumination, increased mental load, and lower overall well-being, potentially causing people to get sick more often - Keeping a secret, even a simple one like avoiding a specific phrase, can temporarily decrease IQ. ### Structuring Thoughts Through Language - Writing down or speaking worries forces thoughts into language, engaging the logical prefrontal cortex and imposing a story structure with a beginning, middle, and end, which combats anxiety from uncertainty. ### Effective Listening and Validation - The most soothing response to someone venting is validation, exemplified by saying 'that sucks' - Validation is more effective than bright siding or asking the person to take perspective. ### Strategic Disclosure Framework - Successful disclosure requires 'disclosure flexibility,' knowing when to be open or guarded based on one's goal (venting vs. influencing change) - A key rule of thumb is to 'go one level deeper than you might think you should' when moving beyond small talk. ### Personal Revelations - Leslie John shared her personal story of under-sharing regarding her first marriage and the revelation that her mother, who advised her to proceed despite her own pre-marital doubts, had also experienced similar issues but withheld the full context of her marriage dynamics, which created a wedge until they discussed it years later.
