Psychological operations (PSYOPs or psy-ops), more recently known as Military Information Support Operations (MISO) by the U.S. military, are planned efforts to influence the perceptions, emotions, attitudes, and behavior of target audiences in support of strategic objectives.
Psy-ops seek to answer a simple question: "How can information be used to encourage people to think, feel, or act in ways that advance a desired outcome?"
The techniques may include persuasion, messaging, symbolism, selective presentation of information, appeals to fear or hope, repetition, social pressure, and the use of trusted messengers.
Modern PSYOP doctrine emerged in an organized form during the 20th century, but there were several much earlier examples.
Historical examples might include Sun Tzu's emphasis on winning without fighting, the Roman use of public spectacles and messaging, propaganda campaigns during the Napoleonic Wars, and leaflets and information campaigns during World War I.
These earlier efforts differed from modern PSYOPs in that they were more often improvised rather than systematic.
Psychological warfare became more formalized during World War II, when governments used radio broadcasts, printed leaflets, rumors, and deception campaigns, news management, strategic messaging, and repetition (loose lips sink ships).
Examples include Allied broadcasts into Nazi-controlled territories, German propaganda directed at Allied troops, and efforts to lower enemy morale and to encourage surrender.
Military planners increasingly viewed information as another battlefield.
The Cold War dramatically expanded psychological operations. Since direct military conflict between nuclear powers was risky, influence campaigns became extremely important.
Both the United States and the Soviet Union invested heavily in propaganda, cultural diplomacy, educational exchanges, broadcasting networks, and intelligence-driven influence campaigns.
Examples included Voice of America, Radio Free Europe, Soviet international media networks, and ideological education programs.
After writing to the Soviet embassy in high school for something I intended to use in a paper I was writing for school, I was subscribed to two monthly glossy magazines. I think they were entitled "USSR Monthly" and "The Soviet Union Today," or something of that sort, and they continued to come until I moved to California after graduating from high school.
The objective was frequently described as winning "hearts and minds," a phrase we still hear often. The target was no longer enemy soldiers but entire populations.
During the 20th century, governments, universities, and military institutions increasingly studied crowd psychology, persuasion, public opinion, advertising, behavioral conditioning, and social conformity.
Edward Bernays, often called the "father of public relations," argued that modern societies are influenced through the management of public opinion. Walter Lippmann, Kurt Lewin, and Carl Hovland were other prominent contributors.
Many of the concepts developed in advertising and public relations overlapped with methods used in strategic influence campaigns.
Techniques developed for wartime persuasion often migrated into civilian institutions.
This doesn't necessarily mean that secret military PSYOPs were being conducted against domestic populations, but neither does it necessarily mean that they weren't.
However, methods and principles of PSYOPs spread into other fields, such as public relations, political campaigning, marketing, public health communication, government information programs, and corporate communications.
The underlying principles remained similar: frame issues strategically, use trusted authorities, repeat key messages, create social norms, and shape perceptions of consensus.
Mass media became one of the most powerful tools for influencing public opinion.
Historically, governments have attempted to influence the media through press offices, public affairs offices, information campaigns, strategic briefings, access journalism, and advertising purchases.
Authoritarian governments or administrations often exert direct control over the media, although less authoritarian governments generally rely more on narrative framing, public messaging, press relations, and strategic communication.
Media organizations themselves influence perceptions through story selection, headline framing, editorial priorities, and the repetition of themes.
Education also influences values and perspectives.
Governments have long viewed schools as a means of civic education, national identity formation, historical interpretation, and cultural transmission. Examples can be seen throughout the political spectrum, such as nationalism in 19th-century Europe, communist ideological education, democratic civic instruction, and wartime patriotic curricula. We see it today in the strong leftist positions propagated by the U.S. educational system.
Whether such efforts are seen as education, socialization, indoctrination, or propaganda often depends on one's political perspective and the methods used. Critics argue that educational systems can become vehicles for ideological influence, while defenders argue that all societies require shared civic knowledge and values.
Another major area is public behavior campaigns.
Governments have routinely influenced behavior concerning smoking, seatbelt use, drunk driving, vaccinations, drug use, and energy conservation.
Common psychological techniques include social proof, appeals to fear, appeals to authority, norm-setting, and repetition.
In recent decades, governments have increasingly adopted "nudge" strategies. Examples include automatic retirement enrollment, organ donation defaults, tax compliance reminders, energy usage comparisons, and cash for clunkers.
Critics argue that nudge campaigns are subtle forms of manipulation, while supporters say they preserve freedom while improving outcomes.
Modern political campaigns use methods that use some PSYOP techniques, such as voter segmentation, personality profiling, message testing, emotional appeals, and social media targeting.
Campaigns increasingly use large datasets to identify who can be persuaded, which messages resonate, and what emotional framing is most effective. Social media has dramatically increased this capability.
Social media represents a new phase in influence operations. Social media algorithms often reward emotional content, identity-driven messaging, fear-based narratives, and confirmation bias.
Government agencies, corporations, activists, political organizations, and foreign actors all compete within this system. Unlike traditional PSYOPs, influence now often occurs through decentralized networks rather than a single centralized authority.
Questions include:
- Where does persuasion become manipulation?
- Should governments influence public opinion?
- If so, under what conditions?
- How transparent should influence efforts be?
- Is a beneficial outcome sufficient justification?
- Who determines what a beneficial outcome is?
- Who determines what information is emphasized or suppressed?
