Ponder on this - in my own experience

"One-Sentence Persuasion" that shows very well the ingredients to make people follow a specific objective

People will do anything for those who encourage their dreams, justify their failures, allay their fears, confirm their suspicions and help them throw rocks at their enemies.

People will do anything for those who encourage their dreams, justify their failures, allay their fears, confirm their suspicions and help them throw rocks at their enemies.
That single 27-word sentence contains five of the most important insights I’ve seen in studying persuasion.
1.  Encourage their dreams.
2.  Justify their failures.
3.  Allay their fears.
4.  Confirm their suspicions.
5.  Help them throw rocks at their enemies.

Removal all doubts results in complete compliance. This is what the Slave Drivers want.
