The act of looking at someone's eyes—the part of them that does the looking—creates an unbreakable feedback loop of "I know you know I know..." This immediately establishes common knowledge, forcing a resolution to the social game being played, whether it's a threat, a challenge, or an invitation.

By openly admitting your inconsistencies while still advocating for a principle, you remove the deceptive claim to unearned status that angers people. This vulnerability prevents a 'gotcha' moment and fosters a more honest conversation, building trust and allowing imperfect people to advocate for important causes.

A six-year-old explained she cries when angry because crying makes her sister comfort her, while anger makes everyone run away. This reveals a fundamental social dynamic: we learn to express sadness to draw people in, while suppressing anger to avoid pushing them away, which can create a disconnect from our true feelings.

There are no universal cues for lying. Instead of assuming a gesture like crossed arms means someone is being deceptive, view it as a change in their state. This change is a signal to become curious and ask clarifying questions.

Contrary to pop psychology, guilt can be a powerful motivator. Guilt makes you feel "I did a bad thing," prompting amends. Shame, however, makes you feel "I am a bad person," leading to withdrawal or aggression. A healthy dose of guilt can fuel moral ambition.

When a norm is violated publicly, it threatens the common knowledge that the norm exists and is enforced. The resulting public punishment, like a digital-age pillory, isn't just about the transgressor; it's a signal to the entire community that the norm is still in effect, thereby restoring common knowledge.

A leader's emotional state isn't just observed; it's physically mirrored by their team's brains. This neurological "energy transference" sets the tone for the entire group, meaning a leader's unmanaged stress can directly infect team dynamics and performance.

Building deep connections isn't just about asking probing questions; it's about reciprocal vulnerability. Super-communicators often volunteer personal information about themselves first. This signals safety and gives the other person implicit permission to share something equally intimate, creating a powerful bond.

Based on a Zen story, "eating the blame" involves proactively apologizing for your part in a conflict, even when you feel your partner is more at fault. This emotionally counter-intuitive act breaks the cycle of defensiveness and creates space for resolution, making it a highly agentic move.
