Which of the following best defines stereotyped thinking?

Stereotyped thinking is characterized by the assumption that all members of a particular group share the same traits, characteristics, or behaviors, regardless of their individual differences. This type of thinking often leads to oversimplified and generalized views about groups of people, ignoring the unique qualities each individual possesses.

When someone engages in stereotyped thinking, they may not take the time to assess a person's unique circumstances or attributes, instead relying on preconceived notions based on their group identity. This can have significant implications in various contexts, such as in the workplace, educational settings, or social interactions, as it can lead to bias and unfair treatment.

The other options, such as believing in new ideas, adapting behavior to different contexts, and evaluating individual merits, do not capture the essence of stereotyped thinking. These alternatives suggest an openness to diversity, individual assessment, and the ability to modify behavior based on situational cues, which contrasts with the rigidity present in stereotyped thinking.
