Logical Fallacy

A logical fallacy is where one uses unsound reasoning to come up with illogical conclusions in argumentation or belief statements. Logical fallacies are either inherent in the logic structure or argumentation tactics and suit irrational desires rather than actual truthful facts.

When arguments or beliefs are structured in a fallacious manner we cannot be guaranteed of the truth. A fallacy does not guarantee an argument will be false, however we know we can’t be sure of truth either. What this means is that if we have a belief that is structured fallaciously that we have to restructure it logically if we wish to justify our belief.

Here is a list of questions to ask yourself regarding a belief to see if it might be structured fallaciously, how to avoid logical fallacies.

Formal and Informal Logical Fallacies

Fallacies are split up into two main divisions, although there are more. Formal fallacies form the basis of fallacies and are defined due to flaws inherent in the structures of the arguments themselves. Informal fallacies are usually argumentation tactics in an argument. These are still grouped together due to the similarity in the flawed conclusions often associated with them.
