Most salespeople fear silence and rush to fill it, appearing insecure. By intentionally embracing silence, you reframe it as a tool. It signals confidence, gives the buyer critical time to process information, and, like a pause in a performance, can make them lean in and pay closer attention.

The key to building deep connection isn't getting someone to say 'you're right,' but 'that's right.' The latter confirms they feel fully seen and heard, creating a neurobiological connection essential for trust, a technique applicable from hostage situations to management.

Since communication is overwhelmingly non-verbal (only 6% words), any feeling of desperation from a salesperson is easily detected. This neediness repels buyers because it signals the focus is on the seller's quota, not the buyer's journey, instantly eroding trust and killing the deal.

People are practiced and guarded during formal meetings. To understand their true nature, Negreanu suggests engaging with them in informal environments like a meal or drinks. This disarms them, making their reactions more authentic and revealing.

In a high-stakes interview, the interviewee used a 'pregnant pause' and spoke slowly instead of using filler words. This projected thoughtfulness and control. In contrast, the interviewer's rapid speech and verbal fillers undermined her credibility and ability to connect with her subject.

Sam Altman's verbal response to a question about OpenAI's finances was reasonable, but his negative body language and audible sigh—perceptible only on video—completely changed the message's reception. This highlights how non-verbal cues in video interviews can undermine a leader's intended message, a critical lesson in the age of multimedia communication.

In virtual settings, the lack of physical presence causes people to "over-index" on the few non-verbal cues available, like facial expressions. A leader's innocuous action, such as rubbing their face, can be misinterpreted as negativity. Leaders must be hyper-aware that their virtual body language is under a microscope.

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.
