A fallacy refers to a faulty argument or argument that is invalid due to problems in the reasoning process, these issues are classified into different types of fallacies such as ad hominem faulty analogy, division, etc. In the case of division fallacy, this occurs when the speaker assumes something is true and valid about the parts that compose a unit just because this is true about the unit or the whole, which means the speaker believes. This occurs in the argument "That baseball team won the World Series, so the players must be outrageously talented baseball players", because the author of this argument assumes all the players are "outrageously talented" because the team or whole is talented, which is invalid as there might be players that are not that talented although the whole team was able to win.
Explanation: The division fallacy is the inverse of the composition fallacy. It is committed when it is inferred that something as a whole has a property by the conclusion that a part of the whole also has that property. Like the fallacy of the composition, this is only a fallacy for some properties; for others, it is a legitimate form of inherence.
