For the purposes of two recent student projects hosted at SICS, we defined a target notion based on trust in lieu of topical relevance. Given controversial search task topics that interested them, subjects performed experiments with enthusiasm and reported that the experiment had influenced their state of mind. This forms an implicit test of trust in the retrieved material. While the respondents reported a medium, to low-medium range of trust in the materials, and did not believe they had found all pertinent facets of opinion pertaining to the topic, they still adjusted their opinions on the matter to some extent and reported having learned about the topic.
