Pairwise comparisons of the seniority groups for the question-answering motivation scales revealed no significant differences, except for the Build Community Ties scale. Graduate students had the highest mean rank compared with the rest of the seniority groups and had a significantly higher mean rank than did full professors (see Fig 4). One might suggest that senior researchers are already a part of the “invisible college”  and have accrued significant social capital . Hence, senior researchers may be less motivated than graduate students to forge new community ties through RIMSs.
