In George Orwell's Animal Farm, various propaganda techniques are used to manipulate and influence the animals. These include name-calling of opponents like Snowball, creating a bandwagon effect to encourage the animals to support popular ideas, and using red herrings to distract the animals from important issues. Testimonials from respected figures like Boxer are also employed to endorse Napoleon's leadership. Circular arguments and repetition of slogans are additional techniques seen in the novel.
