Final answer:
The correct option is 1) Stereotyping.
The incorrect assumption about Ken being on the basketball team due to his height is an example of stereotyping, which is the application of generalized beliefs to individuals based on group characteristics.
Step-by-step explanation:
The mistake in judgment that leads people to assume Ken is a member of his high school basketball team because he is 6'6" illustrates the impact of stereotyping. Stereotyping occurs when we apply a generalized belief to an individual based on their membership in a particular group without considering individual differences. This cognitive bias affects our perception and can lead to expectations that may not be true for every individual within that group.
For example, assuming someone is athletically inclined due to their height is a stereotype because height is often associated with sports like basketball. This bias persists despite various individual experiences that may not align with the stereotype. It is important to recognize that just because an individual has a characteristic commonly linked to a stereotype, it does not mean they conform to the generalized beliefs associated with it.
