Paul Linebarger's Psychological Warfare, published in 1948 and drawn from his experience advising Allied PSYOP operations in the Second World War, is the foundational practitioner text on information operations as an instrument of military strategy. Linebarger — a political scientist at Johns Hopkins who also wrote science fiction as Cordwainer Smith — synthesises the full history of wartime psychological operations from the Mongol conquests through Napoleonic propaganda to the leaflet campaigns, radio broadcasts, and rumour operations of the Second World War.
The book is not merely historical. The operational principles Linebarger articulates — that effective PSYOP targets specific audiences with specific messages calibrated to their specific vulnerabilities; that the goal is behaviour change, not belief change; that credibility is the most valuable and most fragile asset of any information operation — remain foundational to how military and intelligence practitioners think about IO today. For those who work in the field, reading this book reveals how consistently the techniques of modern influence operations draw on principles established in mid-twentieth century military doctrine. Essential historical context for understanding the current threat landscape.
