Critical thinking skills shield you from manipulation and error. To think clearly, you must recognise the flaws in reasoning that permeate daily life. These flaws, known as logical fallacies, appear in politics, advertising, and even your own internal monologue.

This guide breaks down exactly how these deceptions work and how you can spot them.

The Anatomy of an Argument

Before you identify mistakes, you need to understand the structure of an argument.

Premise and Conclusion: Every argument consists of two specific components. The premises provide the evidence or statements of fact. The conclusion is the result you derive from that evidence. If the premises are weak, the conclusion fails.

Deductive Reasoning: This follows a top-down approach. You start with a general rule and apply it to a specific case to reach a certain conclusion.

Inductive Reasoning: This uses a bottom-up approach. You observe specific instances and use them to form a general, likely rule.

What Is a Logical Fallacy?

A logical fallacy is a flawed or deceptive argument. The speaker uses it to convince you of something untrue. This happens accidentally through sloppy thinking or purposefully to manipulate opinion.

Understanding fallacies requires categorising them.
