What is a logical fallacy?

Simply put, a logical fallacy is a mistake in reasoning due to a misconception or presumption. If the premises of an argument are true, the argument can still be rendered invalid if the logic used to come to the conclusion is not legitimate. That is, if the logic is “fallacious”.

Our brains tend to take shortcuts when solving problems – called “heuristics”. These shortcuts are handy, and are true most of the time, but they can lead us down the wrong path when they are substituted for valid (formal) logic.

People can easily and unintentially fall victim to logical fallacies, but can also use them purposefully to win an argument against a person who doesn’t understand them. So, the best way to employ sound logic when arguing is to identify and understand them.

There are many lists of logical fallacies, but the folks over at YourLogicalFallacyIs.com have created a handy infographic/wall poster, so you can stealthily learn your logical falacies and win your next argument.
