Auto suggestion is defined as the act of hypnotizing oneself or inducing self-suggestion or belief. The antonyms for this phrase are external suggestion, coercion, and manipulation. External suggestion refers to a form of persuasion where an individual forcefully advises someone to act or behave in a certain way, contrary to their own beliefs. Coercion, on the other hand, involves using threats or intimidation to compel someone to comply with a specific action or belief. Manipulation is also an opposite term for auto suggestion since it means manipulating someone's thoughts, emotions, or behavior to achieve a particular goal. Therefore, the antonyms for auto suggestion suggest overt manipulation or control of someone's beliefs or choices.
