Dr. Hiro used to be a failed salesman. No matter what he sold, no one would buy it. But one day, while watching the news, he remembered that there was a cult in our world that sold unreliable products at high prices and made its followers donate all their money. So why can't I sell it? So he started to study those techniques seriously. He read every book on brainwashing on the market and applied them until he became a top salesman in Japan. That's the origin of Dark Psychology. Meet the psychological techniques that help you use words to control people's minds, making them follow and do what you want without realizing it.
