Pierce calls the "Three Great Premises" of talk radio: "First Great Premise: Any theory is valid if it moves units ... Second Great Premise: Anything can be true if someone says it loudly enough ... Third Great Premise: Fact is that which enough people believe. Truth is measured by how fervently they believe it.
