In this episode of The Mel Robbins Podcast, Harvard Business School professor Leslie John shares research on how strategic vulnerability and self-disclosure build trust and influence in personal and professional contexts. John's studies reveal that people overwhelmingly prefer openness over secrecy, even when disclosures involve negative information, and that sharing authentic weaknesses can enhance leadership credibility and drive business success.
The conversation also examines the hidden costs of withholding thoughts and feelings, from decreased cognitive performance to emotional disconnection in relationships. John and Robbins discuss practical tools for emotional expression, including "I feel" and "I need" statements, and explore how cultural norms—particularly around masculinity and professional competence—shape patterns of emotional suppression. The episode offers frameworks for moving beyond superficial interactions toward deeper, more authentic connections.

Harvard Business School professor Leslie John's research demonstrates that strategic vulnerability and self-disclosure have powerful effects across personal and professional contexts, from dating to leadership.
John's experiments show people overwhelmingly prefer openness, even when disclosures are negative. In dating scenarios, 65% preferred partners who admitted having multiple STDs over those who refused to answer, while 89% of hiring decision-makers favored candidates who admitted past failures over those who withheld their worst grades. This pattern reveals that disclosure signals trustworthiness—by exposing vulnerability, the discloser communicates implicit trust, which recipients are likely to reciprocate.
Avoiding disclosure creates the opposite effect, leading people to assume dishonesty. Neuroscientific studies support this, showing that sharing personal details activates brain pleasure centers, making self-disclosure intrinsically rewarding and linked to improved well-being and emotional intelligence.
Strategic vulnerability extends beyond personal relationships into business success. John describes how Commonwealth Bank of Australia disclosed credit card drawbacks on their website, which unexpectedly increased customer retention and acquisition, earning millions and inspiring competitors to adopt similar transparency.
In leadership, John encourages executives to include weaknesses in self-introductions, which humanizes them without diminishing perceived competence. Sharing authentic emotions—like tears linked to meaningful stakes—further boosts credibility. Catalyst confessions, where influential figures reveal stigmatized truths, can shift cultural attitudes. Magic Johnson's 1990s HIV disclosure exemplifies this, leading to an estimated 900 additional people seeking HIV testing immediately after his announcement and dramatically reshaping public conversation around the disease.
Mel Robbins and Leslie John explore how undersharing—keeping thoughts and feelings to oneself—carries significant mental, physical, and interpersonal costs.
John explains that people begin suppressing emotions the moment they wake up, creating mental heaviness that accumulates quickly. Studies reveal that secret-keeping decreases cognitive performance and lowers IQ scores on tests due to the constant mental labor of deciding whether to share. Research shows that frequently withholding information leads to worse physical health outcomes, with physiological studies demonstrating that emotional expression alleviates stress responses.
Despite routine exchanges with colleagues or spouses, people can remain emotionally disconnected. John explains that polite conversations—with all the trappings of connection like smiles and eye contact—lack the vulnerability of true intimacy, leaving people "socially full, but emotionally malnourished." Withholding true feelings also means missing opportunities for support, reassurance, and collaborative problem-solving.
Cornell psychologist Tom Gilovich's research shows 76% of life regrets involve actions not taken and words unspoken, rather than risks taken. Palliative nurse Bronnie Ware documents that not sharing feelings openly ranks as the third most common deathbed regret, underscoring the profound cost of persistent emotional withholding.
John describes how her therapist's "emotions wheel" helped her develop emotional vocabulary. The wheel progresses from broad categories—positive or negative, active or calm—to nuanced labels, helping distinguish thoughts from genuine emotions. She emphasizes that increasing emotional intelligence through such tools leads to greater self-awareness and effective emotional communication.
John explains that beginning statements with "I feel" followed by an emotion invites empathy rather than defensiveness, as feelings are not arguable. Following with "I need" shifts conversations from complaints to collaborative solutions, such as "I need you to listen" or "I need help figuring this out." Robbins adds that this framework is simple yet effective across relationship types—personal, professional, and casual interactions.
John suggests linking statements to personal meaning rather than neutral observations. For example, instead of commenting on others' laughter, try "I don't remember the last time I laughed that hard. When did you last laugh really hard?" This approach moves dialogue beyond trivial topics to shared humanity, fostering positivity and authentic connections through deeper questions.
Societal expectations around emotional expression shape how people learn to display or suppress feelings, creating lasting impacts on relationships and mental health.
John references longitudinal research showing that by kindergarten, boys have learned to suppress emotions through cultural conditioning, not biology. Robbins shares how phrases like "be strong for mom" become internal mantras shaping emotional life into adulthood, illustrating how boys internalize the belief that "real men don't cry."
In professional settings, women face a double bind: being penalized for showing emotion and judged as "cold" for restraint. John suggests leaders can reframe emotional expression as passion for their work, saying something like "I'm crying because I care so much about our stakeholders." However, she warns this approach is risky, especially for women, as emotional displays are easily misinterpreted as weakness. John emphasizes that recognizing these cultural patterns as beliefs rather than truths creates space to choose vulnerability as strength, rather than silence as safety.
1-Page Summary
Research by Harvard Business School professor Leslie John highlights the powerful effects of strategic vulnerability and self-disclosure. From dating and hiring to business and leadership, intentionally revealing sensitive information can build trust, boost influence, and even catalyze cultural change.
Leslie John’s experiments show that people overwhelmingly prefer openness, even when the information disclosed is negative. For instance, in a dating scenario, 65% of people preferred a potential partner who honestly admitted to having had multiple STDs over someone who refused to answer the question. When applied to hiring, the effect is even stronger: 89% of people would rather hire someone who admitted to failing in the past than someone who opted out of sharing their worst grades. This indicates that strategic revelation of sensitive information is consistently viewed as a sign of trustworthiness.
Revealing something personal signals trust to the other person—by exposing a vulnerability, the discloser relinquishes control and implicitly communicates, “I trust you with this information.” When people receive this trust, they are more likely to reciprocate and develop a sense of mutual trust and genuine connection. This principle underpins strong relationships, both personal and professional.
Avoiding disclosure often has the opposite effect. People assume a hider is being evasive or dishonest, reducing trust even if the motive was to avoid negative judgment. Disclosure breaks this cycle, encouraging authenticity and deeper relationships.
Neuroscientific studies reinforce this idea. When people share personal details, the pleasure centers of their brain—the same old structures linked to primal rewards—become active. This means truthful self-disclosure is intrinsically rewarding. People are hardwired to feel good when they reveal their authentic selves, which can improve well-being, increase happiness, and reduce stress and rumination. Enhanced emotional intelligence follows, as openness leads to better self-awareness and a greater capacity to understand and process emotions.
Strategic vulnerability does not only apply to personal relationships; it drives success in business and leadership as well. Dr. John describes a striking experiment with the Commonwealth Bank of Australia, where the bank disclosed drawbacks—such as high interest rates and fees—on their credit card site. Instead of deterring customers, this openness increased both customer retention and acquisition, ultimately making the bank millions. The results were so successful that the approach was adopted more widely and copied by competitors, demonstrating that acknowledging imperfections can actually enhance trust and loyalty.
In leadership, strategic self-disclosure further strengthens bonds. John encourages executives to include a few ...
Strategic Vulnerability and Disclosure In Building Trust and Influence
Mel Robbins and Harvard Business School professor Leslie John explore the often-overlooked dangers of undersharing—keeping thoughts, feelings, and truths to oneself. While many people fear oversharing and value emotional restraint as maturity or a boundary, research shows that the mental, physical, and interpersonal costs of withholding are often far higher.
From the moment people wake up, they begin suppressing thoughts and emotions: feeling tired or unhappy, noticing signs of aging, or being overwhelmed. Leslie John explains that this steady flow of unspoken truths accumulates quickly, leading to a mental heaviness—by 9:30 AM, many people already feel “full” of unsaid things. Mel Robbins admits she’s lived this, replaying moments where she “kept it light,” avoided honest conversation, or decided an issue wasn’t “worth bringing up.”
Leslie John details how the mental labor of secret-keeping decreases cognitive performance. Studies reveal that people holding secrets ruminate constantly, continuously deciding whether to share or not, which lowers mental focus and even IQ scores on tests. These unresolved “disclosure decisions” aren’t trivial—collectively, they become an overwhelming mental load.
Research shows that frequently withholding information leads to lower objective measures of physical health. Those who keep secrets often experience worse wellbeing and health outcomes. Leslie recounts physiological research with preschoolers: when children viewing a scary movie openly showed fear, they had calmer sweat responses—demonstrating that emotional expression alleviates physiological stress.
The process of constantly evaluating what should be shared creates a psychological loop, occupying one’s mind and fueling anxiety and rumination. People make disclosure decisions without realizing it, like choosing not to voice a need for emotional support or help, and these choices accumulate throughout the day, leaving individuals feeling burdened by the weight of unsaid things.
Leslie John and Mel Robbins discuss how, even in marriages or close relationships, people can remain “sequestered in [their] own experiences.” Robbins shares that, despite 26 years of engagement and routine with her husband, they felt emotionally disconnected because they weren't truly expressing what was happening inside.
Routine, polite exchanges—like responding "great" to a colleague or discussing weekend plans with a spouse—have all the trappings of connection (smiles, eye contact, shared activities) but lack the vulnerability of true intimacy. Leslie John explains these create an illusion of connection, leaving people “socially full, but emotionally malnourished,” especially for introverts.
Despite being surrounded by people and regular conversation, loneliness and a sense of emptiness persist when meaningful self-expression is absent. Surface-level interactions, Leslie notes, leave people "socially full, but emotionally malnourished." Robbins reflects that many people, herself included, can spend years socially active yet emotionally isolated.
Withholding true feelings means missing out on reassurance, empathy, and suppor ...
Undersharing's Hidden Costs: How Withholding Information Harms Health and Relationships
Leslie John describes the transformative effect of developing a robust emotional vocabulary. She recounts how her therapist equipped her with an "emotions wheel" to better identify her feelings. The wheel begins with broad categories—positive or negative, thumbs up or down—then narrows to whether emotions are active or calm. This results in combinations like positive/active (joy, excitement), positive/calm (peaceful), negative/active (anger, rage), or negative/calm (boredom). The outer layer of the wheel subdivides these further, moving from general emotions to nuanced labels (e.g., anger branches into disappointment, rage, etc.), offering a clear structure for articulating precise feelings.
Leslie John shares her initial struggle, as she was a "recovering emotional illiterate" who would respond to her therapist's inquiries with cognitions—statements like "I feel trapped" or "I feel like this doesn't make sense"—which are thoughts, not genuine emotions. Differentiating between thoughts and feelings is a skill that requires practice, and the emotion wheel serves as a helpful guide.
She emphasizes that increasing emotional intelligence (EQ) through tools such as the emotion wheel leads to greater self-awareness and a stronger ability to understand one’s emotions and those of others. This self-awareness is foundational for vulnerability, which in turn enhances openness and effective emotional communication.
Leslie John explains that beginning a statement with "I feel" and completing it with an emotion is a crucial act of vulnerability. Unlike thoughts, which can invite debate around logic or correctness, feelings are personal and inherently valid—they are not up for argument. By expressing real feelings, a person invites empathy and care rather than defensiveness, especially in close or intimate relationships.
John continues that following "I feel" with "I need" helps individuals connect with and express what would support them, moving conversations from complaint to constructive dialogue. For example, "I need you to just listen," "I need you to be on my side," or "I need your help figuring out what I might be missing." She notes that articulating needs makes it more likely they’ll be met since partners or listeners can’t read minds.
Mel Robbins adds that the "I feel, I need" formula is simple and effective, not only in personal relationships but also with work colleagues and in casual interactions. This framework provides a practical, universal way of increasing openness and promoting understanding, regardless of context.
The "I feel, I need" method is highlighted as both versatile and powerful, applicable to various types of relationships—from romantic or familial interactions to professional environments and everyday encounters. Its effectiveness stems from inviting genuine emotion and actionable clarity into conversations.
Practical Skills For Openness: "I Feel" & "I Need" Statements, Deeper Questions, Emotional Intelligence
Societal expectations around emotional expression shape how boys and girls learn to display or suppress their feelings. These cultural beliefs, rather than biological factors, create lasting impacts on relationships, mental health, and professional dynamics.
Leslie John references longitudinal research revealing that by kindergarten, boys have already learned to hold in their emotions, even though, as preschoolers, they expressed feelings as openly as girls. This shift occurs through cultural conditioning, not biology, resulting in boys becoming "stoic" and emotionally reserved due to societal expectations.
Mel Robbins shares a story of a boy at a funeral being told to "be strong for mom," a phrase that became an internal mantra and shaped his emotional life well into adulthood. Leslie John notes that such moments illustrate how boys internalize the idea that "real men don't cry," leading to lifelong patterns of emotional suppression.
This social conditioning produces physiological and psychological consequences, negatively impacting boys’ ability to process emotions and form healthy, open relationships.
In professional settings, revealing emotion is fraught with risk, especially for women. Leslie John highlights the double bind women face: being penalized for showing too much emotion and judged for being "cold" if they restrain themselves.
Leslie John suggests that rather than concealing emotion, leaders can reframe emotional expression as passion for their work or commitment to stakeho ...
