Veiled threats or polite requests convey a message without making it "official" common knowledge. This preserves the existing social relationship (e.g., friends, colleagues) by providing plausible deniability, even when the underlying meaning is clear to both parties.

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.

Helms suggests that refusing to answer an invasive or difficult question in a high-stakes setting like a job interview can surprisingly project confidence and command respect. It turns a potentially weak moment into a demonstration of strength and control.

When frustrated by something you can't control (traffic, a colleague's behavior), the phrase 'let them' serves as a practical tool. It's not about condoning behavior but about accepting reality to conserve your mental energy. This allows you to focus on what you *can* control: your own response.

The generic offer "let me know if I can help" rarely gets a response. Asking "What does support look like right now?" is a more effective, direct question. It gently shifts the burden to the other person to define their needs, making them more likely to accept help and reducing resentment.

The concept of a universal "attention span" is a myth. How long we focus depends on our motivation for a specific task, not a finite mental capacity that gets depleted. This reframes poor attention from an innate inability to a lack of interest or desire.

In difficult discussions, choosing not to respond is a powerful tool. It serves as a boundary on yourself to prevent a reactive, unhelpful comment and is a conscious choice when you recognize a conversation is unproductive. It's about control, not passivity.

To elicit candid answers from fund managers, the most effective technique is not the question itself but the silence that follows. Resisting the psychological urge to fill the space forces the manager to sit with the question, often leading to less rehearsed and more truthful responses.

People often mistake cynicism for intelligence. However, research shows it's a protective measure used by those with poorer reasoning skills to avoid being taken advantage of. This self-protection leads them to miss out on positive human interactions by assuming the worst in others.
