10 Common Informal Fallacies You Need to Know

Introduction

In today’s age of information overload and easy access to knowledge, it is essential to be able to critically evaluate arguments and reason. The ability to spot logical fallacies is an essential skill that everyone should possess. Logical fallacies are errors in reasoning that can lead us to wrong conclusions and beliefs.

In this article, we will discuss ten common informal fallacies that you need to know. By the end of this article, you will be better equipped to identify and avoid fallacious reasoning.

What is a Fallacy?

Before we dive into specific fallacies, let’s first define what we mean by a fallacy.

A fallacy is an error in thinking that occurs when the reasons given for a claim do not provide sufficient support for the conclusion. Fallacies can be categorized into two types: formal and informal fallacies. Formal fallacies occur when the logical structure of an argument is incorrect while informal fallacies occur due to mistakes in reasoning.

Ten Common Informal Fallacies

1. Ad Hominem Fallacy

This fallacy occurs when an argument is attacked based on the characteristics of the person making the argument, rather than the content of the argument itself. For example, if a politician is criticized for supporting a particular policy because they are a member of a particular political party, rather than the merits of the policy, that is an ad hominem fallacy.

2. Appeal to Authority Fallacy

This fallacy occurs when an argument is accepted simply because it is made by an authority or an expert. Just because someone is an expert in a particular field does not mean that everything they say is automatically correct. Instead, we should evaluate the arguments and evidence presented by the authority.

3. False Dilemma Fallacy

This fallacy occurs when an argument presents only two options, when in reality, more options exist. For example, if someone argues that we must either cut taxes or suffer economic ruin, they are presenting a false dilemma.

4. Slippery Slope Fallacy

This fallacy occurs when an argument suggests that a series of events will inevitably lead to a particular outcome, without sufficient evidence to support that claim. For example, if someone argues that accepting a particular social policy will lead to the collapse of society, that is a slippery slope fallacy.

5. Straw Man Fallacy

This fallacy occurs when an argument misrepresents the opponent’s position in order to make it easier to attack. For example, if someone argues that their opponent believes in a particular extreme position, and then attacks that position, even though their opponent never actually held that position, that is a straw man fallacy.

6. Hasty Generalization Fallacy

This fallacy occurs when a conclusion is drawn from insufficient evidence. For example, if someone meets one person from a particular country who is rude, and then concludes that all people from that country are rude, that is a hasty generalization fallacy.

7. Red Herring Fallacy

This fallacy occurs when an argument introduces irrelevant information in order to divert attention from the main issue. For example, if someone is accused of a crime and responds by talking about the weather, that is a red herring fallacy.

8. Appeal to Emotion Fallacy

This fallacy occurs when an argument is made using emotional appeals, rather than reasoned arguments and evidence. For example, if someone argues in favor of a particular social policy by showing a tearjerker video, that is an appeal to emotion fallacy.

9. Circular Reasoning Fallacy

This fallacy occurs when an argument assumes the very thing that is being argued for. For example, if someone argues that a particular book is the best because it is the most popular, and the reason it is the most popular is that it is the best, that is a circular reasoning fallacy.

10. Confirmation Bias Fallacy

This fallacy occurs when we only seek out information that confirms our existing beliefs, and ignore information that contradicts them. For example, if someone only reads news sources that are biased towards their political views, that is a confirmation bias fallacy.

Conclusion

Learning to identify and avoid logical fallacies is an important skill in reasoning and critical thinking. By understanding the common informal fallacies outlined in this article, you will be better equipped to evaluate arguments and reason in a more logical manner. Remember, always analyze the reasons given for an argument and evaluate them on their own merits and never accept an argument simply based on the authority of the speaker.
