Trying to make people feel fear and anxiety for no reason is unethical and may cause psychological harm to others. This is not recommended. But if you are discussing it from the perspective of understanding certain psychological manipulation methods, the following are some examples of extreme and undesirable methods.： Create false and sensational information: spread some unfounded but terrifying-sounding rumors, such as fabricating upcoming disasters, social turmoil, etc. Excessive rendering of uncertainty: Continuous emphasis on various uncertain factors in life makes the other party feel that everything is difficult to control, and they are full of confusion and worry about the future. Long-term psychological suppression: constantly denying the opponent's abilities and efforts, causing them to doubt whether they can cope with the future, which in turn causes fear. However, we should advocate positive, healthy and positive exchanges and interactions, get along with people in a friendly, supportive and constructive way, and jointly create a good interpersonal relationship and social environment.
