Internet offers people with intellectual disabilities (ID) unique opportunities to access information and to participate in society. But concerns have been raised about the potential risks they face when accessing the Internet (e.g. giving credit to false information, being exposed to manipulative content). As part of the current debate between positive risk-taking and overprotection, our study empirically tested the extent to which 43 adults with ID identified and selected topically relevant as well as trustworthy web pages while searching the Internet for several topics (e.g. Can socialnetworks use your pictures for advertisement?). Participants also justified their search decisions. Results revealed that while searching familiar topics (i.e. social networks), participants selected more relevant and trustworthy pages than irrelevant and less trustworthy ones. Searches of less familiar topics (i.e. daily health), were carried out randomly, that is, without applying a specific criterion. Results point to the importance of topic familiarity on people's with ID performance on Internet searching tasks. This pattern of results suggests that, first, we should avoid overprotection when people with ID search for familiar topics and, second, they need more support when searching for information about less familiar topics.
