Argumentum ad Populum
Also known as 'appealing to the people', this fallacy presumes that a proposition must be true because most/many believe it to be true.
Example of Argumentum ad Populum
- Extended warranties are a very popular purchase by the consumer, so extended warranties must be good for the consumer. The fact that something is popular has no bearing on whether it is beneficial.
- Everyone drives over the speed limit, so it should not be against the law. Just because a lot of people do something, it does not make it the right thing to do.
