Is reasoning based on false or invalid arguments.

Fallacious reasoning.

Explanation:

As the exercise briefly describes, fallacious reasoning is based on false or invalid arguments. This makes it deceptive, given that if unaware of what makes the argument invalid, the false logic in which this type of reasoning is failed could be understood not as a fallacy but as logical and true. Many times, when trying to deceive, fool, manipulate, etc, people will use this kind of reasoning, the one that is based on false, invalid arguments.
