More: The second paper… contains a way around this problem.… "with explicit labeling, older adults were able to discount their stereotypes and avoid processing difficulties when subsequent stereotype-inconsistent information was encountered… when counter-stereotypical information is explicitly provided at encoding (that is, the first stage of the memory process, in which stimuli are initially registered), older adults are no more likely than younger adults to rely on stereotypes, and are similarly capable of altering their interpretation of a situation when information suggests that information is incorrect."

In real life, of course, no one is pointing out biased statements as they emerge from the mouths or friends, family members or talk-show hosts. So for older adults, the best advice might be to avoid acquaintances who speak in stereotypes. This research suggests prejudice can be contagious, and we become more susceptible as our brains age.
