ELI5: What's a logical fallacy?
A logical fallacy is just a statement that is not logically correct, or drawing a conclusion from an argument that does not logically follow. It can apply to formal or informal logic. A formal logic example is something like this: If an animal is a dog, then it has four legs. My cat has four legs. Therefore, my cat is a dog. That's obviously incorrect, as cats cannot be dogs. Much more common in every day life are informal logical fallacies. There are far too many to list, but a common one that most people are familiar with is the straw man, where a person intentionally misrepresents someone else's position in order to attack the false position and not the real one. An example of this would be: Bob: "I like having a pet dog". Alice: "Why do you hate cats?" Here, Bob never said anything about cats, but Alice drew out that false inference in order to attack Bob.

December 29, 2011 - Examples: “I know the exam is graded based on performance, but you should give me an A. My cat has been sick, my car broke down, and I’ve had a cold, so it was really hard for me to study!” The conclusion here is “You should give me an A.” But the criteria for getting an A have to do with learning and applying the material from the course; the principle the arguer wants us to accept (people who have a hard week deserve A’s) is clearly unacceptable. The information the arguer has given might feel relevant and might even get the audience to consider the conclusion—but the information isn’t logically relevant, and so the argument is fallacious.

A logical fallacy is a pattern of reasoning that is rendered invalid by a flaw in its structure. It is not the use of false information. It is not the use of an argument that actually weakens your position. An example of a logical fallacy would be if you were discussing economic systems and argued "Nobody likes that person, so their argument is wrong." Their popularity doesn't determine if they are correct or not so this line of thinking is flawed. This general structure of attacking the person instead of their argument can be summarized as a certain kind of logical fallacy.
