Final answer:
Ageism is reinforced by stereotypes that create negative beliefs about different age groups, leading to discrimination. This can be seen in employment situations where older and younger adults may face ageist attitudes when applying for a job.
Step-by-step explanation:
Ageism is a form of prejudice and discrimination based on age. Stereotypes play a role in reinforcing ageism by perpetuating negative beliefs about different age groups. For example, older adults may be stereotyped as incompetent and physically weak, while younger adults may be seen as immature and irresponsible. These stereotypes can lead to discrimination in various areas, such as employment. An older adult and a younger adult applying for a sales clerk position may face ageism, with the older adult being perceived as less capable and the younger adult being seen as lacking experience.
