Yesterday I spent some of my time learning about informal fallacies. If you do not know what a fallacy is, it an error in logic. There are two types of fallacies: informal and formal. A formal fallacy is based on disobeying the formal rules of logic. An informal fallacy is a specific, usually easy to remember, name for a combination of formal fallacies.
A example of an informal fallacy is the “No true Scotsman” fallacy. This fallacy is the way of reinterpreting evidence in order to prevent refutation of ones position. An example of this fallacy is Brian throws his toys. No good kid throws their toys, therefore Brian is not a good kid. So that is a some of what I learned yesterday.
Fallacies are important so you can know when someone is trying to fool you.
