Overview

Jordan Harbinger speaks with Dr. Leslie John, Harvard Business School professor and author, about the underrated power of strategic oversharing. They explore how revealing personal information can build trust and connection, while also discussing the risks of TMI, disclosure hangovers, and how to calibrate authenticity across different contexts. The conversation covers everything from dating app disclosure dilemmas to workplace vulnerability, examining when opening up strengthens relationships and when it backfires.

The Art of Opening Up: Trust Through Vulnerability

Dr. Leslie John introduces the counterintuitive idea that revealing personal information—even things that feel slightly uncomfortable—can actually build trust faster than waiting until we feel safe. The conversation establishes that while we tend to wait until we trust someone before opening up, reversing this order by sharing first is what actually generates trust. The key is that revealing something edgy communicates that you already trust the other person, which makes them trust you back.

  • We typically wait until we feel comfortable before opening up, but opening up first is what causes others to trust us
  • When we share something edgy, we're communicating 'I trust you' through the act itself, not just through the content
  • Con artists weaponize this principle by sharing fabricated vulnerabilities to build false trust
  • Many people, especially men, struggle with vulnerability due to concerns about appearing weak or unmascaline
" Oftentimes we kind of wait until we feel comfortable and feel like we can trust someone and then open up. But if we do it in the reverse, where we open up a little bit, a little bit more than we think we should, not STDs and rashes, but yeah, maybe my pet puked on me this morning or my baby, whatever. That is what causes others to trust us back. "
" Slightly inappropriate over shares are my love language. "

The Twenty-Year Lesson: John and Grace's Missed Connection

Dr. John shares the story of John and Grace, who fell in love in their twenties but never expressed their feelings due to fear of rejection and saying the wrong thing. They spent twenty years apart, married other people, and had children—all because neither had the courage to reveal their true feelings. When they reconnected two decades later, they finally shared what they'd been holding back and are now together, having made a pact to always share their feelings with each other.

  • John and Grace loved each other in their twenties but never said so, leading to 20 years apart
  • Grace had a ticket to visit John in Australia but wanted him to say he loved her first; he showed up at the airport but she never boarded
  • When evaluating whether to reveal feelings, people focus only on risks of revealing, not on risks of staying silent or benefits of opening up
  • 80% of the time when someone says 'I love you' first, it's requited—far higher than most people expect
" In the process of trying to say the right thing, they said nothing at all. And then the worst happened, essentially. It's like this self-fulfilling prophecy in a way. "
