Bandwagon and Testimonial are two main propaganda techniques described in this lesson.
Step-by-step explanation:
Two of the seven main propaganda techniques described in this lesson are:
1. Bandwagon: This technique is used to create a sense of belonging or to make people feel like they are missing out if they don't join a particular group or support a certain cause. For example, a propaganda poster might say, 'Join the winning team!' or 'Don't get left behind!'
2. Testimonial: This technique involves using a well-known person or celebrity to promote a product or idea. The idea is that if someone famous supports it, then it must be good. For instance, a poster might show a famous actor using a certain brand of toothpaste and claim that it is the best.
