3. Do not use fear tactics if you have no evidence

We believe that fears and phobias can motivate the person to act in a different manner. Learn to get your ideas across by using a different way of persuasion. You do not want to deal with people who are struck with the sense of fear. It is very hard to make the opponent trust your extreme reasoning. If you have plenty of evidence, then you can prove you are right. If not, refrain from using fear tactics since what you say will be called lies. 

4. Do not appeal to ignorance

By dismissing an idea to be untrue, you should not think that the contrasting idea is true. For instance, you cannot say that BMW manufacture the best cars on the planet just because Audi may not be reported to be the best since there have been too many cases where the latter model broke. In reality, owners of the former model have experienced plenty of trouble as well.
