A logical fallacy has to do with the faulty conclusion which is gotten when making an argument that is invalid based on the available facts and premise.
There are different types of fallacy and some of them include:
Straw man fallacy
Fallacy of hasty generalisation
Appeal to force
False dilemma
Faulty analogy, etc
The main aim of a logical fallacy is to give a faulty conclusion that is not logical at all but misleading and incorrect on careful observation.
