What error is displayed when someone assumes all politicians are corrupt based on a few examples?

The assumption that all politicians are corrupt based on only a few examples is known as a hasty generalization. This error occurs when someone draws a broad conclusion from a limited sample size, which does not accurately represent the larger group. In this case, the individual is taking a few instances of corruption and generalizing this behavior to all politicians, leading to an unfair and inaccurate stereotype. Hasty generalizations lack sufficient evidence and can lead to misconceptions about groups or categories, demonstrating a flaw in logical reasoning where one leaps to conclusions without a proper basis in the available information.

In this instance, recognizing that not all politicians engage in corrupt practices requires a more comprehensive and nuanced understanding than what is provided by a few negative examples. This reflects the importance of critical thinking in evaluating claims and forming beliefs based on complete evidence rather than isolated incidents.
