One group in our society that is particularly vulnerable to misinformation is older adults. While older adults have been recognized as being of high risk for misinformation, this demographic has been under-researched in the dark side of IT literature. This research-in-progress study seeks to understand how individual, medium, and message characteristics influence individuals’ susceptibility toward misinformation and how these factors influence misinformation susceptibility differently across younger and older adults. A lab experiment is also proposed to verify the proposed relationships. This proposed research will provide much needed understanding on how older adults are impacted by the IT threat of misinformation and how to design support to encourage resilience to misinformation that results in improved well-being and mobility for older adults.
