Brené Brown: Why we reach for armor instead of courage

Brown defines vulnerability as the emotion we feel in moments of uncertainty, risk, and emotional exposure. After testing this with groups like the US Special Forces and NFL teams, she found no example of real courage that does not include vulnerability. If you know the outcome in advance, it's not courage. Practically, this means actions like saying “I love you” first, sharing honest fears at work, or pursuing a dream without guarantees are inherently vulnerable—and necessary for a brave life.

Brown emphasizes that fear itself isn’t what blocks courage; it’s the protective strategies we learned to survive—perfectionism, control, rage, disengagement, people-pleasing. These once-adaptive defenses become destructive in adulthood, especially in midlife, when the challenge is to recognize what no longer serves us. She describes this as the universe grabbing you by the shoulders and saying: “Your armor is getting in the way. Let go of what doesn’t serve, or there will be consequences for you and others.”

Using the “marble jar” story from her daughter’s school, Brown shows that trust accrues through minor but reliable actions: remembering names, checking in when someone’s absent, offering a seat, noticing when someone’s struggling. In leadership, asking about an employee’s family or being transparent in a crisis adds marbles. Conversely, cheating or slow emotional disengagement can smash the jar entirely. Leaders often overestimate what saying “trust me” can do; what really matters is their accumulated behavioral track record.

Brown distinguishes four types of power: power over (controlling, fear-based), power with (collaborative), power to (enabling others’ agency), and power within (grounded self-worth and self-knowledge). Power over is fragile: to maintain it, leaders must periodically enact cruelty toward vulnerable groups to keep people afraid. More sustainable leadership uses co-creation, shared decision-making, and self-awareness. In organizations, power over eventually leads to numbness, normalization of toxicity, or burnout.

Drawing from systems theory, Brown explains that individuals, companies, and societies are all interacting systems. Healthy systems allow feedback in and out—especially uncomfortable feedback—so they can adapt to complexity (AI, geopolitics, social change). When systems shut down input to avoid uncertainty, they become self-referencing (“Are we good? We’re great.”) and start to decay. Leaders’ instinct to “close the drawbridge” under pressure is understandable but dangerous; long-term resilience requires keeping those boundaries permeable.
