Introduction

Logical fallacies are common errors in reasoning that weaken arguments and make them appear more convincing than they are. They often arise when claims lack evidence or rely on irrelevant points, creating the illusion of logic without real support.

"We are most often inspired and motivated by fallacy rather than logic."

M.F. Moonzajer, Journalist, Linguist and Author

Fallacies work because they tap into intuition, emotion, or bias. They can sound persuasive even when the reasoning is flawed, leading people to accept conclusions that don't follow from the premises.

Many fallacies rely on weak or insufficient evidence. A hasty generalization draws broad conclusions from too little data, while a post hoc fallacy assumes one event caused another simply because it came first.

Other fallacies distract from the issue. Ad hominem attacks target the person instead of the argument, and genetic fallacies judge ideas by their origin rather than their merits, shifting attention away from evidence.

Some fallacies distort arguments. A straw man misrepresents a claim to make it easier to attack, while false dichotomies present only two choices when more exist, limiting thoughtful evaluation.

Recognizing fallacies requires slowing down and asking whether evidence truly supports a conclusion. This habit strengthens critical thinking and helps avoid being misled by flawed or manipulative reasoning.

Learning to identify fallacies improves judgment, supports clearer communication, and helps us navigate complex information environments with greater confidence and fairness.

There are two main types of logical fallacies: formal and informal. Formal fallacies involve errors in the structure or form of an argument, while informal fallacies arise from errors in the content, context, or delivery of the argument.
