Flattery is insincere praise used to persuade people by appealing to their ego. It works because people want to believe compliments and agree with those who flatter them. Flattery can be used to trick people into doing things or believing things they otherwise wouldn't by making them feel good about themselves. Examples show how flattery makes requests seem less like chores or makes products seem more appealing to buy. Flattery also appeals to national pride to encourage helping those less fortunate.
