Logical fallacies are flawed arguments that appear valid but contain errors in reasoning. Some common examples:
Ad Hominem: Attacking a person’s character or background instead of addressing their argument. For example, “You can’t trust his opinion on climate change because he’s a politician”.
Tu Quoque: Another form of Ad Hominem, in which a person’s behavior or past beliefs are called into question to discredit their current argument. Also called Appeal to Hypocrisy, the fallacy that someone being a hypocrite automatically discredits the argument at hand. For example, “Doctors say smoking causes lung cancer, but doctors smoke all the time.”
Red Herring: Diverting attention from the main issue by introducing irrelevant information. For example, A politician accused of misconduct might deflect by talking about a recent bill they passed that has nothing to do with the scandal.
Irrelevant Conclusion: Describes a conclusion that is irrelevant to the premises allegedly supporting it. For example, “Fire can’t be dangerous to humans because it keeps us warm in the winter.”
Straw Man: Misrepresenting someone’s argument to make it easier to attack. For example, “My opponent wants to abolish all taxes, but I don’t think that’s a good idea”.
Begging the Question: A logical fallacy in which the validity of the conclusion is buried in the premise of the argument. It is a premise restating the conclusion without supporting the conclusion. For example, “I’m the boss (conclusion) because I get to make the final decision on everything (premise).” ( It doesn’t actually explain why the boss gets to make those decisions.)
False Dilemma: Presenting only two options when more exist, forcing a choice between them. For example, “You’re either with us or against us”.
False Analogy: Also known as Weak Analogy, drawing a comparison between two things that are not similar in the relevant aspects. For example, “Because surgeons use X-rays during operations, students should be allowed to use their textbooks during exams.”
Hasty Generalization: Drawing a conclusion based on a small or unrepresentative sample. For example, “I met two rude people from that city, so everyone there must be rude”.
Slippery Slope: Arguing that a small action will inevitably lead to a series of negative consequences. For example, “If we legalize marijuana, then everyone will start using heroin”.
Guilt by Association Fallacy: Where a negative trait of one person is assumed to apply to another due to their connection. This fallacy can be used to unfairly discredit someone or their arguments, even if the association is not indicative of their own guilt or wrongdoing. For example, “John supports a new tax policy, and John is friends with a known criminal. Therefore, John must be a criminal as well.”
Bandwagon Fallacy: Arguing that something is true or good because many people believe it or do it. Also called Argument to Popularity, which is simply peer pressure, not sound logic. For example, “Everyone is buying this product, so it must be good”.
Causal Fallacy: Incorrectly concluding the cause of an event. For example, “I wore this shirt and we won the game, so wearing this shirt causes us to win.”
Genetic Fallacy: Focusing on the source or history of an argument instead on the argument itself. For example, rejecting a religious belief because it was taught by your hypocritical parent. This happens because people often confuse:
* Reasons with causes
* Psychological with logical explanations
* The sources with the content of arguments
Argument from Incredulity: This occurs when you argue that something can’t be true solely because it’s difficult to imagine, hard to understand, or else doesn’t conform to your particular worldview. For example, “Your argument doesn’t align with my spiritual or political beliefs. Therefore, it’s wrong.”
Appeal to Authority: Claiming something is true simply because an authority figure said it, without considering the context or expertise. For example, “This medicine works because my doctor told me so”.
Appeal to Tradition: Rather than interrogate the logic behind a certain action, the argument assumes the action is logically sound because it’s been done for a certain amount of time. The fallacy says “we’ve always done it this way.”
Appeal to Consequences: argues that a premise is correct or incorrect based on whether the outcome is positive or negative. In other words, if a certain hypothesis leads to an undesirable consequence, the hypothesis “must” be wrong; if the consequence is positive, it “must” be right. For example, “It’s impossible to spend all your money gambling because then you couldn’t afford to eat.”
Appeal to Emotion Fallacy: a type of informal fallacy that occurs when someone attempts to manipulate the emotions of an audience to win an argument, often in the absence of factual evidence or logical reasoning. While pathos (the use of emotion in rhetoric) can be a powerful tool, it becomes a fallacy when it’s used instead of logic and evidence to support a claim:
Appeal to Fear: “If we don’t pass this bill, our economy will collapse!”
Appeal to Pity: “You wouldn’t want to see these children suffer, would you?”
Appeal to Ignorance: Claiming something is true because it hasn’t been proven false. In other words, the fallacy is that the absence of counterevidence means there is no counterevidence.
Appeal to Flattery: “You’re such a smart and capable person, I know you’ll agree with me.”
Appeal to Ridicule: “People who believe that are just plain stupid.”
Aaand, The Fallacy Fallacy occurs when you assume that an argument is incorrect just because it contains a logical fallacy!
