Manipulation is the art of getting people to behave differently from what they would have done spontaneously while giving them the feeling that they have acted freely. The manipulator tries by different means to lead people in a desired direction. And, like it or not, manipulation is everywhere, at work, in social or family relations, in the media, in sales, etc. You will find in this book some of the tools which are both simple and effective in changing people's prism of observation and leading, them without constraint, to adopt a positioning aligned with yours.
