Logical Falacies and How to Spot Them

When you are having a debate with someone, it is important to be able to identify logical falacies they may use against you to win the argument or weaken your position.

Logical falacies errors in reasoning that can make arguments seem convincing, but are ultimately flawed. They can be found in everyday conversations, media, politics, and even in academic research. In this blog post, we will discuss some of the most common logical falacies and how to identify them.

Ad Hominem

Ad Hominem is a Latin phrase that means “to the person”. It is a logical falacy that attacks the person making an argument rather than the argument itself. It is a common logical falacy used in politics and media especially when emotions run high. Examples of ad hominem fallacies include:

• “You can’t trust his opinion on climate change because he’s a Republican.”
• “She’s just a know-it-all, so her argument must be wrong.”
• “Why should we listen to him? He’s never even been to college.”

Straw Man Fallacy

The straw man fallacy involves misrepresenting an opponent’s argument in order to make it easier to attack. This is often done by taking the argument out of context, oversimplifying it, or exaggerating it. Examples of straw man fallacies include:

• “You think we should have stricter gun control laws? So you want to take away our Second Amendment rights?”
• “You believe in evolution? So you don’t believe in God?”
• “You think we should reduce carbon emissions? So you want to shut down the entire oil and gas industry?”
• “You don’t celebrate pride month? You don’t believe in human rights.”

False Dichotomy Fallacy

The false dichotomy fallacy presents only two options when there are actually more. This type of fallacy is often used in politics or marketing to create a sense of urgency or to make people feel like they have to choose one option over another. Examples of false dichotomy fallacies include:

• “You’re either with us or against us.”
• “Either we pass this bill or the economy will collapse.”
• “You’re either a dog person or a cat person.”
• “If you don’t support the military coup in your country, you support terrorism”

Slippery Slope Fallacy

The slippery slope fallacy argues that if we allow one thing to happen, it will inevitably lead to a series of increasingly negative consequences. This type of fallacy is often used in politics to create fear or to discourage people from taking action. Examples of slippery slope fallacies include:

• “If we allow the government to regulate guns, it will lead to the government taking away all our rights.”
• “If we allow illegal immigrants to stay, it will lead to a complete breakdown of our society.”

Appeal to Authority

The appeal to authority fallacy involves using the opinion of an authority figure as evidence to support an argument, without any actual evidence to back it up. This type of fallacy is often used in advertising or politics to lend credibility to an argument. Examples of appeal to authority fallacies include:

• “Nine out of ten doctors recommend this product.”
• “The CEO says this is the best course of action.”
• “The WHO says that masks are effective, so we should all wear them.”
• “I read it on the internet, it must be true.”

Appeal to Emotion

Appeal to Emotion is a logical falacy that attempts to convince the audience that an argument is true by appealing to their emotions. Examples of appeal to emotion fallacies include:

• “If you don’t support the government’s plan to fight climate change, you must hate the planet.”
• “If you don’t wear a mask, you don’t love your elderly mum.”
• “Don’t let them take away your freedom! Vote for me.”

False Cause Fallacy

The false cause fallacy assumes that just because one event follows another, the first event caused the second event. This type of fallacy is often used in superstitions or conspiracy theories. Examples of false cause fallacies include:

• “I got sick right after I got my flu shot, so the flu shot must have made me sick.”
• “Every time I wear my lucky socks, my team wins. Therefore, my lucky socks must be the reason we win.”
• “The stock market crashed after the president took office, so it’s all his fault.”

As a general rule, just because two events happen at the same time, it doesn’t mean that one caused the other, or more fancily said: “Correlation does not imply causation”.

Appeal to Ignorance

Appeal to Ignorance is a logical falacy that attempts to convince the audience that an argument is true because it has not been proven false. Examples of appeal to ignorance fallacies include:

• “I don’t know if climate change is real, so I’m not going to do anything about it.”
• “I don’t know if masks are effective, so I’m not going to wear one.”

Appeal to Popularity

Appeal to Popularity is a logical falacy that attempts to convince the audience that an argument is true because it is popular. Examples of appeal to popularity fallacies include:

• “Everyone is wearing a mask, so I should too.”
• “Everyone is talking about climate change, so it must be real.”

Argument from Intimidation

Argument from Intimidation is a logical falacy that attempts to convince the audience that an argument is true by threatening them. Examples of argument from intimidation fallacies include:

• “If you don’t support the government’s plan to fight climate change, you will be arrested.”
• “If you don’t wear a mask, you will be fined.”

Loaded Question Fallacy

The loaded question fallacy involves asking a question that is based on a false assumption or premise. This type of fallacy is often used in interviews or debates to trap the person being questioned. Examples of loaded question fallacies include:

• “Have you stopped beating your wife yet?”
• “Why do you hate this country?”
• “Don’t you think it’s time we took action against these illegal immigrants?”

Circular Reasoning Fallacy

The circular reasoning fallacy involves using the conclusion of an argument as the premise. This type of fallacy is often used in debates or discussions where there is a lack of evidence. Examples of circular reasoning fallacies include:

• “I’m always right because I’m never wrong.”
• “The law is always right because it is the law.”
