The analysis of motivations for the question-answering activity identified four scales (see Table 5). Expertise had significantly higher ratings than did the rest of the scales. Answering questions from other researchers was the most cognitively expensive activity among the three activities used in this study to define the RIMS participation levels. Successful completion of the question-answering activity requires information systems to successfully match questions with the competence respondents have. Ardichvili and colleagues  found that the fear of providing an inaccurate answer and, as a result, losing face among peers was one of the main barriers to knowledge sharing in an online community of practice. Research communities are competence-based communities  that assign the highest priority to the accuracy and reliability of information . Hence, it is not surprising that participants rated feeling competent as the highest motivation for the question-answering activity. It is noteworthy that External Pressure again was rated the lowest and below the neutral value on the Likert scale for the survey question (i.e., 4). Researchers do not appear to be very receptive to prompts received from RIMSs to answer questions posted by other members. One participant noted,
