Without exception, everyone wants to influence others. You convinced your colleague that it was better to do something. Successfully conducted complex negotiations. The buyer purchased the item. The spouse did what you asked. All this influence. People use manipulation unconsciously. But it is better to know the laws of the human psyche and apply them consciously. It is better to learn how to influence people effectively. Life will be much more comfortable. You learn about the nature of manipulation, who needs to manipulate others. How to manipulate information, promises. How to use your appearance, limit your choice and create contrast. We use conditional reflexes of a person, we control it through approval or comfort. We use blackmail, provocation or authority. Create a sense of community, care or scarcity. We use feelings of pity or guilt. We use mutual concession or scandal. We learn to protect ourselves from manipulation, at work or in the family. We competently refuse and avoid bad people.
