Other meanings of Psychological warfare
Military & Strategy
Psychological warfare (PSYWAR) is the use of psychological tactics to influence, demoralize, or manipulate opponents, often through propaganda, threats, and disinformation, aiming to achieve objectives without direct physical combat.
Psychological warfare (PSYWAR) is the planned use of propaganda, threats, and other non-lethal techniques to influence the attitudes, emotions, and behavior of adversaries, neutral groups, or friendly populations. It aims to demoralize, confuse, or manipulate opponents, often to reduce their will to fight or to gain support for one's own cause. The term is distinct from psychological operations (PSYOP), which in U.S. doctrine includes both psychological warfare and psychological consolidation activities, but in common usage the two are often conflated.
Psychological warfare has ancient roots, from Sun Tzu's emphasis on subjugating the enemy without fighting to Roman and Mongol use of terror tactics. The modern concept emerged in World War I with propaganda leaflets and radio broadcasts, but the term 'psychological warfare' was formally adopted by the U.S. military in the 1940s. During World War II, both Axis and Allied powers employed extensive PSYWAR, including the British Political Warfare Executive and the U.S. Office of War Information. The Cold War saw its institutionalization in agencies like the CIA and the KGB, with operations ranging from Radio Free Europe to covert disinformation campaigns.
Common techniques include propaganda dissemination via leaflets, radio, television, and the internet; disinformation to spread false or misleading information; intimidation through shows of force or threats; and appeals to fear, nostalgia, or ideology. In modern conflicts, social media and cyber operations have become key vectors, enabling targeted manipulation of public opinion and perception. Psychological warfare can also target individuals, such as interrogation techniques that exploit psychological vulnerabilities, though these are subject to legal and ethical constraints.
One of the most studied campaigns is the Allied use of leaflet bombing in World War II, dropping billions of leaflets over enemy lines to encourage surrender and undermine morale. In the Vietnam War, the U.S. ran the 'Phoenix Program' and used 'Wandering Soul' tapes to exploit Vietnamese beliefs about the afterlife. More recently, in the Gulf War, coalition forces dropped leaflets and broadcast messages that contributed to mass surrenders of Iraqi troops. The Islamic State's use of social media for recruitment and intimidation is a contemporary example of non-state psychological warfare.
Psychological warfare is governed by international law, including the Geneva Conventions, which prohibit certain forms of propaganda and coercion, such as forcing prisoners to make statements or using threats of violence. The principle of distinction requires that PSYWAR not target civilians directly, though propaganda aimed at civilian populations is often used. Ethical debates center on the manipulation of truth and the potential for unintended consequences, such as inflaming conflict or causing long-term psychological harm to populations.
Beyond the well-known campaigns, psychological warfare has included niche operations like the 'Ghost Army' of World War II, which used inflatable tanks and fake radio transmissions to deceive German forces. In the Cold War, the U.S. dropped 'surrender passes' over Korea and Vietnam, and the Soviets used 'active measures' to spread disinformation about the U.S. AIDS virus. A lesser-known fact is that the term 'psychological warfare' was first used in English in a 1940s U.S. Army manual, but the concept of 'perception management' has since evolved to include cyber operations and information warfare. Another edge case is the use of 'psyops' in domestic contexts, such as police negotiation tactics, which are not typically classified as psychological warfare but share similar techniques.
Psychological warfare remains a critical component of modern military strategy, evolving with technology and media.
