Research has consistently found nominal group brainstorming (in which members work separately without communicating) to be superior to brainstorming in which group members interact verbally. This article presents the results of an experiment that found the reverse to be true for computer-mediated electronic brainstorming. In this experiment, 12-member electronically interacting groups generated more ideas than did 12-member nominal groups, and there were no differences between 6-member electronic and 6-member nominal groups. The authors attribute these results to the ability of electronic brainstorming to introduce few process losses (production blocking, evaluation apprehension, and free riding) while enabling process gains (synergy and the avoidance of redundant ideas).
