Trust is not a given; it's the outcome of being trustworthy. Leaders build this by consistently demonstrating accountability, transparency, and a willingness to receive feedback. The focus should be on modeling trustworthy behavior, which in turn inspires the team's confidence.

Citing Brené Brown, the speaker argues that trust isn't earned by "saving the day" on a schedule or feature. Instead, it is forged through small, daily actions like asking questions, learning each other's tools, and demonstrating genuine interest in each other's work.

To foster trust within competitive teams, ex-WPP President Karen Blackett uses a formula from 'The Trusted Advisor'. It requires members to be credible, reliable, empathetic, and—crucially—to have low self-orientation, prioritizing the team's success over individual gain.

The strength of a team's trust isn't defined by avoiding mistakes, but by a leader's willingness to go back, take responsibility, and "repair" after a conflict. This builds more security than striving for perfect, error-free leadership.

While consistency is valuable, emotional stability is more critical for leadership, especially in turbulent times. A leader with a stable, predictable temperament provides psychological safety and prevents team-wide panic. This mental health-centric view of leadership fosters a more resilient and trusting environment than simply being consistent with actions.

Trust is not built in major events but accumulated through small, everyday actions of care and reliability. These 'marbles'—like remembering a personal detail or offering a seat—fill a metaphorical jar. Leaders with full jars don't need to ask for trust in a crisis; it's already there.

Instead of asking explicit questions about values, potential business partners can rely on years of shared professional experience. Observing decision-making under real-world pressure provides a more authentic assessment of cultural alignment than formal Q&A sessions.

Honesty alone is insufficient for leadership because day-to-day realities can be volatile. Effective leaders provide stability by being consistently honest. This creates a predictable environment, manages expectations, and allows team members to know exactly what they are signing up for.

Trust isn't built on words. It's revealed through "honest signals"—non-verbal cues and, most importantly, the pattern of reciprocal interaction. Observing how people exchange help and information can predict trust and friendship with high accuracy, as it demonstrates a relationship of mutual give-and-take.
