Veiled language in sensitive situations, like a romantic advance, doesn't aim to hide the speaker's true intent. Instead, it prevents that intent from becoming undeniable common knowledge. If rejected, both parties can pretend the message was taken at face value, which preserves the prior relationship by avoiding a public acknowledgment of the failed bid.

While we claim to value directness, relationships are built on shared fictions and assumptions that would be destroyed by blunt honesty. For example, explicitly stating the limits of a friendship ('I can only talk for 25 minutes') would kill it, even if true. Indirectness is necessary to maintain these foundational ground rules.

Sophisticated blackmail doesn't involve direct threats. Instead, the blackmailer presents themselves as a rescuer from a fabricated threat. For instance, they'll claim a third party has compromising material and offer to 'handle it,' thereby gaining the victim's trust and lifelong compliance without appearing to be the aggressor.

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.

Paltering is a specific form of dishonesty distinct from lying. It involves strategically using truthful statements to intentionally mislead someone into forming a false conclusion. This allows the speaker to deceive while maintaining plausible deniability of having lied.

We use hints and innuendo not to deny what we said, but to avoid a state where both parties know the other knows the true intent. This "common knowledge" can irrevocably change a relationship, whereas indirectness allows a shared fiction (e.g., a platonic friendship) to continue even after a proposition is rejected.

People are more effective at deceiving others about their true motivations when they first deceive themselves. Genuinely believing your own pro-social justification for a self-interested act makes the act more compelling and convincing to others.

When trying to deceive someone, admitting a genuine, less critical flaw can make you seem honest and self-aware. This vulnerability makes the primary lie more credible because the listener thinks, "Why would they tell me this bad thing if the other part wasn't true?"

When people communicate indirectly (e.g., saying "leave me alone" but meaning the opposite), they are often protecting themselves from vulnerability. It forces the other person to prove they care enough to dig deeper, without the speaker risking explicit rejection.
