Which of the following best describes stereotyping?

Stereotyping is best described as judging someone based on group perceptions. This means assigning traits, characteristics, or behaviors to an individual based on their membership in a particular group, rather than considering their unique personal attributes or experiences. This process often leads to oversimplified and generalized beliefs about individuals, which can be misleading and unfair.

The other options indicate a focus on understanding individual differences or recognizing complex identities, which are contrary to the nature of stereotyping. Analyzing someone's unique personality and recognizing individual differences involve a nuanced view, while cultivating understanding of complex identities suggests an appreciation for the rich diversity within groups. These approaches help to break down stereotypes rather than reinforce them. Therefore, option B, which emphasizes the judgment based on group perceptions, accurately captures the essence of stereotyping.
