before starting the video we should know about what is fallacy a fallacy is the use of in logical or faulty reasons for an argument that may appear to be well reasoned if unnoticed the term was introduced in the western intellectual tradition by the Aristotle during his work in organon which he identified 13 fallacies fallacies may be committed intentionally to manipulate or influence a person's beliefs attitudes intentions motivations or behaviors by convincing one or many people within true information because of human carelessness cognitive or social biases and ignorance or potentially due to the limitations of language
and understanding of language fallacies are commonly divided into formal and informal a formal fallacy is a flaw in the structure of a deductive argument that renders the argument invalid while an informal fallacy originates in an error in reasoning other than an improper logical form arguments containing informal fallacies may be formally valid but still fallacious appeal to Authority it describe as in insisting a claim is true simply because an expert or authority makes it without supporting evidence for example this diet must be healthy because my favorite celebrity endorses it straw man it refers to misrepresenting or
