Psychological warfare is the use of psychological tactics and techniques to influence, manipulate, or deceive an adversary or target group for strategic or military purposes. This includes the use of psychological and communicative strategies to shape perceptions, beliefs and behaviors. Psychological warfare uses a variety of methods, including propaganda, disinformation, media manipulation, psyops, and social engineering. Its objectives range from demoralizing the enemy, influencing public opinion, instilling fear and submission, and gaining strategic advantage. Psychological warfare is often used in conflict situations, intelligence operations, and political campaigns. In parallel with conventional military and political strategies, psychological vulnerabilities and prejudices are used to achieve desired psychological outcomes.
