Abstract
This study of the utility of evidence differs from previous studies in its use of a respondent‐generated matrix of information and sources. This matrix comprised three dimensions (expertness × trustworthiness‐acquaintanceship x information type] and was used to produce Q‐statements which subjects sorted according to a most useful‐Jeast useful criterion in three hypothetical decision‐making situations. The Q‐analysis revealed several types of persons, including: types which found directive information most useful, types which preferred unknown but competent sources, and types which depended upon sources who were known and trusted regardless of the kind of information the source offered.
