How is a logical fallacy defined?

A logical fallacy is defined as an error in reasoning that undermines an argument. This definition emphasizes that a logical fallacy occurs when reasoning is flawed, making the argument less convincing or entirely invalid. Logical fallacies can stem from various issues, such as improper assumptions, irrelevant evidence, or mistaken connections between premises and conclusions. As a result, recognizing logical fallacies is fundamental in critical thinking, as it helps identify weaknesses in arguments and supports the pursuit of reasoned and rational conclusions. Understanding this definition is crucial because it allows individuals to critically evaluate arguments and enhance their reasoning skills.
