How we change what others think, feel, believe and do
Principles > Deception principle
Alter the other person's perception by tricks, untruths and other forms of deception.
In order to live with one another, most people largely trust other people for most of the time. This lays them open to untruths, illusions and downright lies.
The golden rule of deception is management of the other person's perception such that they do not know any deception is happening.
Lies are very difficult to tell face-to-face, as much communication is through body language and voice tone. The results of such lying is that the other person receives a mixed message and may well detect the deception.
To successfully tell lies, you need first to be able to lie to yourself. If you totally believe what you are saying, then you will be able to tell any lie with complete conviction. This is how actors are able to successfully assimilate other characters and draw you into the story plot.
Economy with the truth

More elaborate deceptions can be used that include factors such as:
Be very careful with deception: if the other person finds out then they may well act in a betrayed manner, taking revenge on you in ways that far outweigh the damage you have done with your deception.
