Which kind of ageism is most common?

Over 80% of respondents in a poll of 84 individuals aged 60 and older reported encountering ageism, like others presuming they have cognitive or physical problems because of their age. According to a 2001 survey done by Duke University’s Erdman Palmore, Ph.D., the most typical form of ageism- reported by 58 percent of respondents- was being told a joke that made fun of seniors. 31% of those surveyed stated they were neglected or mistreated due to their age. This research was published in The Gerontologist (Vol. 41, No. 5).
