What is a fallacy?

A fallacy is an invalid or misleading reasoning that seems correct and convincing. Fallacies are frequently found in lots of fields, especially when arguing for or against causes or all sorts of interests. Every sincere communication should avoid fallacies as much as possible. It’s also useful to know which they are and how to detect and fight them.

Our goal is to explain the basics of the most common fallacies, using a format that makes it easy to share on social media. We are motivated by the desire of promoting rational thinking, to have a good head on our shoulders. We hope you like it.
