How we change what others think, feel, believe and do
Use deception and other forms trickery to get them to do what you want them to do. Use what works and do not worry too much about what is moral or not. If they challenge you, just bluff it out.
For example you can:
A child tells his mother he wants a bicycle, saying 'everybody else has got one'.
Don't worry sir, it will be delivered to your door on Monday.
We have been called the 'mendacious ape' in reflection of the extent of the deceit we use. In fact one possibility for our large brain is so we can dream up ever-cleverer deceptions. When the only rule is to win, the ability to deceive gives the clever person a huge advantage over someone who is stronger than them.
The danger, of course, with deception is that if you are found out, all trust that has been placed in you will be lost and you may be subjected to social punishment such as being ostracized from groups to which you and the other person belong (in particular their circle of friends).
While it is not necessarily recommended, this website includes many deceptive
methods. This is because deceit is a very common element in negotiation and
other persuasive settings, and what we do here is describe how the world works
as much as show you how you can change minds.
Deceit is the 20th of the 64 compliance-gaining strategies described by Kellerman and Cole.
