Top Twenty Logical Fallacies

Consider how often public discourse is influenced by numerous logical fallacies. We are bombarded with so much propaganda that it dulls our ability to notice logical inconsistencies. Faulty arguments have become so common and are repeated so frequently that some people mistake these flawed patterns for sound reasoning. 

Here's a list of the top twenty fallacious arguments and a simple illustrative example for each:

Ad Hominem (Attack the Person): Attacking the character or attributes of the person making an argument rather than the argument itself. Example: "You can't believe Alice's argument on climate change because she isn't a scientist."

Ad Ignorantiam (Argument from Ignorance): Asserting that a proposition is true because it has not been proven false, or vice versa. Example: "There's no evidence that ghosts don't exist, therefore they must be real."

Ad Populum (Appeal to Common Belief): Arguing that a claim must be true merely because a significant number of people believe it. Example: "Many people believe in astrology, therefore it must be true."

Ad Verecundiam (Appeal to Authority): Using an authority as evidence in your argument when the authority is not really an expert on the facts relevant to the argument. Example: "My professor said that this political theory is true, so it must be."

Ad Misericordiam (Appeal to Pity): Attempting to induce pity to sway opponents. Example: "You must agree that my late nights at the office demonstrate I deserve a raise."

Ad Baculum (Appeal to Fear): Creating support for an idea by instilling fear in those considering an argument. Example: "If you don't support the policies of the party, you'll be considered a traitor."

Ad Novitatem (Appeal to Novelty): A fallacy of assuming that something newer is automatically better or superior. Example: "This new model of phone must be better because it just came out."

Ad Antiquitatem (Appeal to Tradition): Arguing that a practice or policy is good or acceptable simply because it's traditional. Example: "We should continue to do it this way because we've always done it this way."

Circulus in Demonstrando (Begging the Question): When an argument's premises assume the truth of the conclusion, instead of supporting it. Example: "God must exist because the Bible says so, and the Bible is true because God wrote it."

Non Sequitur: An argument in which the conclusion does not follow logically from the premises. Example: "She's wearing red shoes. She must be a fun person."

Post Hoc Ergo Propter Hoc (Post Hoc): Assuming that because B comes after A, A caused B. Example: "I started doing better at school when I started wearing new shoes. Therefore, the new shoes caused my improved grades."

Straw Man: Misrepresenting someone's argument to make it easier to attack. Example: "He thinks we should manage resources better, which means he wants to put thousands of companies out of business."

False Dilemma (False Dichotomy): Presenting two opposing options as the only possibilities, when in fact more possibilities exist. Example: "You're either with us, or against us."

Slippery Slope: Arguing that a relatively small first step will lead to a chain of related events culminating in some significant impact. Example: "If we allow students to redo their assignments to improve grades, next they'll want to retake entire courses."

Hasty Generalization: Making a rushed conclusion without considering all of the variables. Example: "Three of my friends bought this phone and had problems, so this model must be bad."

Red Herring: Introducing an irrelevant or secondary subject and thereby diverting attention from the main subject. Example: "Why worry about surveillance when there are so many people suffering from poverty?"

Ad Fidentia (Appeal to Flattery): Using flattery to win an argument or to distract from a lack of evidence. Example: "As a smart voter, I'm sure you can see why this policy makes perfect sense."

Ad Invidia (Appeal to Spite): Making an argument through spite or prejudice towards a group to which the opponent belongs. Example: "We should not listen to his argument because he's a part of the corporate world."

Tu Quoque (Personal Inconsistency): Answering criticism with criticism, or turning the argument back on the accuser. Example: "How can you argue your point about diet when you eat fast food all the time?"

Ad Ridiculum (Appeal to Ridicule): Mocking an argument rather than providing evidence against it. Example: "Are you really suggesting we should invest in wind farms? Might as well go back to sailing ships!"


For an article about the top twenty fallacies, you could imagine a visually engaging and thought-provoking image that encapsulates the concept of logical fallacies. Here’s a description for such an image:

The central focus is a large, ornate, ancient-looking book opened on a pedestal. The book's pages are filled with symbolic illustrations representing different fallacies. Each page of the book shows a unique, vibrant, and slightly whimsical depiction of a fallacy. For instance:

Ad Hominem: A cartoonish figure pointing an accusatory finger at a mirror.

Ad Populum: A large crowd where each individual is a clone of the next.

Straw Man: A scarecrow dressed in a suit, standing in a field, with real people debating it.

Slippery Slope: A small figure sliding down a literal slippery slope that gets steeper and darker.

False Dilemma: A road splitting into only two paths, both leading to perilous destinations.

Above the book floats a classic balance scale, unbalanced, symbolizing the imbalance that fallacies bring to reasoning. The background is a library with shelves filled with more ancient books, suggesting the long history and persistence of these fallacies in human discourse. Soft beams of light filter through a window, illuminating the scene and giving a sense of enlightenment and discovery.
