As Roger Poorhouse (and others) observe, Hitler was an absolutely spellbinding public speaker. Newly revealed photos show effective oratory required pratice–and we can see him rehearsing hand gestures, facial expressions, posture, and other non-verbal elements.
We can understand how he was able achieve so much as a speaker, particularly in terms of “psychological coercion” from his own writings in Mein Kampf. He writes:
1. Keep the dogma simple. Make only 1 or 2 points.
2. Be forthright and powerfully direct. Speak only in the telling or ordering mode.
3. As much as possible, reduce concepts down into stereotypes which are black and white.
4. Speak to people’s emotions and stir them constantly.
5. Use lots of repetition; repeat your points over and over again.
6. Forget literary beauty, scientific reasoning, balance, or novelty.
7. Focus solely on convincing people and creating zealots.
8. Find slogans which can be used to drive the movement forward.
