- A mass movement – such as Communism, Nazism, French and American revolution, Brexit Leavers/Remainers or even a country supporting their national footbal team – needs
- An enemy (Jews, or a foreign population, or immigrants – historically a sure bet, or the EU used for) Brexit,
- Somethingt feel united for (same origins, nationality, traits or even the same haircut and outfit in an army)
- A leaderable to channel the frustration of the masses (e.g. Unemployment in Germany after WW1, or the football captain, or a populist politician) that indoctrinate the population (Nazi and Communist long operas aiming at affect people’s rationality, or documentaries and catchy political slogans)
- Understandable promises of better conditions (more jobs, less taxes, more money to NHS).
Members of a group feel empowered and supported by each other, feeling to be part of something great, and that generates a big power.
Historically, Short mass movements (French and American Revolution) tends to lead to positive outcome (e.g. democracy), whereas long ones (Nazism and Fascism ) often lead to stalled creativity and development, leading to their failure to keep their promises.
