Why did I say "yes"? We are often dissatisfied with our decisions in retrospect and ask ourselves how this could have happened. Common cause: We were manipulated and once again didn't notice it. This book by Andreas Edmüller and Thomas Wilhelm shows how you can see through the manipulation attempts of your fellow human beings and successfully avert them. In this way, you will learn to represent your own point of view confidently, to avoid argumentation traps and to win others over to your own ideas in a fair way.
