When writing an argumentative essay or preparing for a debate, it is essential to avoid including irrelevant information or making sweeping generalisations.
To strengthen your arguments, here is a list of common logical fallacies to avoid. Once you become familiar with these fallacies, your writing, speaking and debating skills will significantly improve.
1. Slippery slope
What it means: the argument that a small action will lead to a series of negative outcomes without any evidence to support that claim. It occurs when someone suggests that a minor initial step will result in severe consequences.
Example: “If we allow students to retake one test, they’ll expect to retake every test, and soon grades will lose their significance.”
How to fix it: Focus on the facts. While it is effective to use emotional language for emphasis, it is crucial to back your claims with reliable evidence. Exaggerations can lead your audience to dismiss your argument altogether.
2. Red herring
What it means: a distraction that diverts attention away from the main issue
Example: A child caught cheating might say, “I know I shouldn’t have cheated, but my parents will be so disappointed!” This shifts the focus from the cheating to the potential consequences from parents.
How to fix it: Stay focused on the topic at hand. If necessary, acknowledge the distraction, but steer the conversation back to the central issue. Ensure that your reasoning is related to the claim you are making.
3. False dichotomy
What it means: when only two options are presented, even though more alternatives exist
Example: Saying “You’re either with us or against us,” creates a forced choice between complete loyalty and outright opposition. It oversimplifies the situation by overlooking the possibility of nuanced opinions.
How to fix it: Acknowledge that additional options are available. Present a range of possibilities or emphasise the middle ground to make your argument.
4. Sweeping generalisations
What it means: making a broad statement about a group based on limited or no evidence
Example: “Fifty per cent of marriages end in divorce within three years, so I shouldn’t marry you because our relationship is statistically likely to fail.” This statement takes a general statistic and applies it to a specific relationship, overlooking the unique dynamics and commitment levels of the individuals involved.
How to fix it: Use specific, credible evidence. Recognise exceptions and avoid applying broad claims to individuals or unique situations. Precision makes your argument stronger.
5. Straw man
What it means: misrepresenting an argument to make it easier to attack
Example: If a person says, “We should spend more money on education,” and another replies, “So you want to cut off funding to the military?” the second person has distorted the original statement into something it was never intended to be.
How to fix it: Accurately represent the opposing argument before responding. Restate their position correctly, then critique it with evidence rather than attacking a misrepresented version.
