Answer:
Fallacy of composition.
Explanation:
Fallacy of composition also called faulty induction, composition fallacy, or exception fallacy is an assumption which states that the result achieved from an experiment on a section of a population will be true for the entire population. Fallacy of composition often lead to incorrect conclusion as what is good for a part of a bigger population may not always be good for the whole, example is when a spectator in a stadium stands up, he gets a better view of the game, but when everybody stands up, the opposite is the case.
