Large Language Model Counterarguments in Older Adults: Cognitive Offloading or Vulnerability to Moral Persuasion?

This effect is much stronger in older populations than in younger ones. The AI acts as a cognitive prosthetic that can effectively override a person's long-held ethics. This vulnerability suggests that AI could be used to manipulate the moral compass of the elderly. Digital assistants are not just providing information, they are actively reshaping the personal values of their most vulnerable users.
From the abstract
This study examined whether counterarguments generated by large language models (LLMs) influence the moral judgments of younger and older adults and whether these effects vary as a function of dilemma type, cognitive functioning, trust in AI, and prior experience using LLMs. Using the switch and footbridge trolley dilemmas, 130 participants (56 younger adults and 74 older adults) were presented with ChatGPT arguments that opposed their initial judgments. Results revealed that more than 30% of pa
