![]() On the other hand, the circularity in this argument is due to how things work in real life: if people leave, things get worse. On the one hand, this seems like an example of circular reasoning. Here, the sequence of questions and answers has formed a full circle: the economy is in a bad state because people are leaving, and people are leaving because of the poor economy. People can’t find jobs with the economy being so slow at the moment.” Journalist: “Why are people leaving the state?”Įconomist: “Because the economy is depressed. Things are very poor in the building industry, for example, because there is no need for new housing.” ![]() Circular reasoning fallacy argument Journalist: “Please explain the current economic recession.”Įconomist: “A lot of people are leaving the state. This is problematic because A is both a reason supporting the argument and is itself supported by the argument, forming a circle.Ĭircular reasoning is usually (but not always) fallacious. In the above argument structure, notice that the premises rely on each other for their validity: Person 1: “Because it is the divine work of God.” (C) Person 2: “Why should I believe the Bible?” Person 1: “Because it says so in the Bible.” (B) Circular reasoning fallacy in religion Person 1: “God must exist.” (A) ![]() ![]() The claim relies on its own premise (i.e., “politicians are untrustworthy”) to support its conclusion that only an untrustworthy person would run for president.Īlthough one may find good arguments for the existence of God, people often commit circular reasoning due to their own deeply held belief, which they assume is self-evident. The fact that politicians are untrustworthy is proof of that.” The evidence for this claim is that X is true.” Circular reasoning fallacy in politics“Only an untrustworthy person would run for president. The weakness of such arguments is particularly clear in some cases: “X is true. Simply assuming a claim is true does not serve as evidence for that claim. However, no real explanation is offered as to why it is time to go to bed/it’s bedtime, such as “if you don’t get enough sleep, you’ll be tired at school tomorrow.” Circular reasoning fallacy examples The parent simply restated the claim as supporting evidence. In the previous example, the parent’s first statement (the conclusion in this case) and the justification they offer (the premise) are identical. This happens because the speaker already believes the claim is true. It will use the fact that A can prove B and vice versa. In other words, both the premise and conclusion rely on the other’s truthfulness:īy the end of a circular reasoning fallacy, the argument will have come full circle, without actually having proven anything. How does circular reasoning fallacy work?Ī circular reasoning fallacy consists of an argument that starts with a premise (A) and moves to a conclusion (B), where A is logically equivalent to B either explicitly or implicitly. However, self-validation is poor reasoning: an argument’s claim needs to be supported by actual evidence. In a circular argument, the same proposition occurs as both a premise and a conclusion-the argument validates itself. In other words, it is supported by the evidence presented in the premise. In a good argument, we say that a conclusion follows from the premise. A premise is any reason or evidence that supports the argument’s conclusion. What is a circular argument?Ī circular argument (or circular reasoning) is an argument that comes back to its beginning without having proven anything.Īn argument consists of one or more statements (premise) and a claim (conclusion). Even so, circular arguments can be convincing because repeating the same thing makes it seem self-evident. More specifically, circular arguments are logically invalid because they offer no justification for their conclusion.
