We should first reference that people who successfully manipulate others often tend to pick targets that are much easier to manipulate. This happens in politics all the time. A person can get involved and reference things people agree with. That builds up faith or confidence for you with that group. Then you sprinkle in fakeness or lies, and since you already have them buying that you believe as they do, they are more likely to believe you.
Yet in the real world, being manipulative takes more creativity and targets are sometimes hard to spot. The hardest to manipulate is a generally curious person, as they will never truly believe you unless they do research first. Yet easier targets can be taken advantage of often. That is why this is one of the most toxic personality traits. Those who were manipulated will naturally never want to be around the manipulated again. That makes this one of the few things one can do that, if caught, instantly ends any conversation or relationship for most.
