In Logic, Appeal to the People is an informal fallacy of relevance. This fallacy occurs when someone makes an appeal to fear or desire as support for their conclusion. This fallacy is also known as Appeal to Pity, Appeal to Snobbery, and the Bandwagon Argument. What they all share in common is that what people believe, or what others are doing, is usually irrelevant to establishing the truth of a conclusion.
For example, “All the cool people are voting for Bernie; you should too.” Or, “George Cluny uses an iPhone, therefore they are better than Androids.” Or, John deserves a raise, after all he has a sick child at home and his wife left him.”
