Argument from Authority

You might be tempted to cite someone with more knowledge than you to support your opinion. For instance, "Dan's been in college for three years, and he says it's not what it's cracked up to be." You might use this as evidence that college isn't fun, but you would be committing an argument from authority. Instead of citing evidence for your opinion, you cite someone with more authority who shares that opinion. Keep reading to learn more about Arguments from Authority, different types, and how to avoid them.

      Argument from Authority Definition

      The argument from authority is a logical fallacy. A fallacy is an error of some kind.

      A logical fallacy is employed like a logical reason, but it is actually flawed and illogical.

      The argument from authority is specifically an informal logical fallacy, which means that its fallacy lies not in the structure of the logic (which would be a formal logical fallacy) but rather in something else.

      Here's a simple definition of the argument from authority:

      An argument from authority is when someone uses an authority's words and not their reasoning to justify an argument.

      An argument from authority is also known as an appeal to authority. This is how that looks:

      My friend's a lawyer, and she also said that fair-use law is a sham.

      This person appeals to their lawyer friend to defend the claim that fair-use law "is a sham." However, several things make this argument a logical fallacy.

      Why the Argument from Authority Is a Logical Fallacy

      At first, appealing to the authority of someone knowledgeable on the topic seems like a strong argument. Here's why that isn't always the case.

      • When you appeal to an authority, you may not consider the context of their opinion. You could twist their words or misunderstand their stance.
      • When you make an argument from authority, you might credit someone incorrectly. The authority figure might not be an expert in the exact field you are discussing.

      Take this lawyer example again.

      My friend's a lawyer, and she also said that fair-use law is a sham.

      The person's friend might not be a fair use lawyer. They might not have expertise in the field of copyright or creative property! They might be a personal injury lawyer or estate planning lawyer.

      • Someone might manipulate authority. Someone can use authority manipulatively to lie about something.

      If any of these things happen, the appeal to authority is now a logical fallacy because the argument lacks truth. If logic lacks truth, then its conclusion will also lack truth.

      • Ultimately, an expert's opinion is still an opinion. Someone saying something is just an opinion, even if an authority figure says it. Only evidence supports fact.

      The Legitimate Appeal to Authority

      There are many legitimate appeals to authority. Legitimate arguments from authority occur when you provide evidence alongside the appeal.

      Authorities are not the evidence; authorities merely provide evidence. Take this example.

      A study conducted by over 100 scientists in vaccine research has concluded that Vaccine Z is safe for people of all ages.

      In this example, the authority and their evidence create a strong appeal to authority and a strong appeal to logos (the appeal to reason).

      Inductive Argument from Authority

      At its core, an argument from authority (or appeal to authority) is an inductive argument.

      Induction uses specific examples to draw a more general conclusion. It is the inverse of deduction.

      An appeal to authority takes one or more authoritative opinions and draws a larger conclusion. Take this for example:

      A chemist at Vancom University said that some fossil fuels could be cleaner. We agree with this. All fossil fuels can be cleaner, which is where Clean Coal comes into the picture.

      This argument takes an authority figure's single vague opinion (some fossil fuels can be cleaner) and uses it to support "all fossil fuels can be cleaner" and then to Clean Coal. As you can see, the argument from authority uses individual opinions and statements to draw more significant conclusions.

      Types Of Arguments from Authority

      Here are three more types of appeals to authority.

      Appeal to Anonymous Authority

      This sounds as shady as it is.

      An appeal to an anonymous authority does not specify the authority to which it appeals.

      Here's how that appears:

      Experts conclude that our product will increase your lifespan by 5 to 10%.

      Who are these "experts," and how many are there? What is the evidence? These things need to be provided, or else the appeal is fallacious.

      Appeal to Unqualified Authority

      An unqualified authority doesn't have the credentials you think they do.

      An appeal to unqualified authority attempts to persuade someone using a non-expert as an expert.

      Well, that's no good.

      I'm Dan. I suffered from anxiety once. Let me tell you how to fix yours.

      Although Dan might have suffered from a disorder, this alone does not qualify him to provide psychotherapy or clinical advice. In this example, Dan appeals to his own authority on the subject.

      Arguments from authority do not have to reference the authority. An authority can commit the fallacy by using the weight of their position to influence someone instead of using evidence and logic.

      Appeal to Tradition

      The appeal to tradition does not appeal to a person but rather to precedence.

      An appeal to tradition attempts to persuade someone based on what has been the case before.

      Here's an example.

      We have been fishing this river for decades. No matter what environmentalists say, the fish will be fine.

      This person attempts to appeal to the long-standing tradition of fishing in those parts. What this person fails to realize, however, is that things change. Entire populations have been hunted to extinction, so just because there were enough fish to catch in the past doesn't mean this is sustainable today.

      Argument from Authority Essay Example

      The argument from authority can appear in passages and essays like this one. Examine this passage and try to identify the arguments from authority. Then try to explain why it's a logical fallacy.

      This is not a wild conclusion. While my words are small, others' words are not. Astronomers and scientists—including Dr. Zam Van Zap from the Astronomy Institute of Somewheresville—have often opened the gates to the possibility of alien existence. Aliens are out there. We simply haven't found them… or have we? Government insiders have long leaked the probable truth that high officials in the government know about aliens and UFOs. Enthusiasts and independent researchers have been following the case of aliens for over one hundred years. There is a long history of this for a reason. Yes, aliens are out there."

      The following passages are appeals to authority.

      Astronomers and scientists—including Dr. Zam Van Zap from the Astronomy Institute of Somewheresville—have often opened the gates to the possibility of alien existence.

      This appeal to authority twists the words of an expert to appear broader than they are.

      Government insiders have long leaked the probable truth that high officials in the government know about aliens and UFOs.

      This appeals to an anonymous authority. "Government insiders" is not verifiable or useful in a persuasive argument. This writer needs to be more specific.

      Enthusiasts and independent researchers have been following the case of aliens for over one hundred years. There is a long history of this for a reason. Yes, aliens are out there.

      This final example appeals to tradition. However, just because something has been going on for a long time, it does not mean it makes logical sense now (or ever).

      All these errors come down to one thing: a lack of evidence.

      Avoiding Arguments from Authority

      If you appeal to authority in your argument, you need to pair it with evidence. Authoritative evidence contains a symbiotic relationship between the authority and what that authority concludes. How? Because this kind of evidence contains the meat of the argument (the research evidence) and the person who understands it (an authority).

      This is not to say that an authority who does not provide evidence is wrong. You must always look at each situation differently. Sometimes, an expert might not have the time to explain themselves fully. Often, someone using an authority will provide a link to the details of that authority's research, which is fine. Authorities help us learn things and trust things.

      So here's the bottom line. Include as much information as you can so you don't invite unwarranted speculation. If you appeal to authority without evidence, somebody can discredit you or the authority, even if your statement is correct.

      You want to create a sound line of reasoning in your argument.
