What is considered a method of manipulation?

Using flattery to influence another person is indeed considered a method of manipulation because it involves insincerity with the intent to affect the behavior or feelings of someone else. Flattery often entails exaggerating someone's qualities or achievements to create a favorable impression or to win their favor, ultimately guiding them toward a desired outcome that serves one's own interests. This tactic can cloud judgment and encourage compliance based on emotional appeal rather than rational decision-making.

In contrast, the other options reflect positive and healthy social interactions. Using humor to build rapport facilitates a genuine connection and eases communication. Offering genuine compliments is intended to express appreciation without a manipulative edge, building trust and goodwill. Encouraging teamwork promotes collaboration and a sense of community, which is aligned with promoting well-being rather than steering individuals for personal gain.
