“…This result is of great practical importance, given the often observed difficulty that groups face when pooling and integrating many pieces of information (Reimer, Reimer, & Czienskowski, 2010;Reimer, Reimer, & Hinsz, 2010;Stasser & Titus, 2003;Tindale & Sheffey, 2002;Winquist & Larson, 1998). It implies that the performance of a group is not necessarily raised only by increasing the quantity of information exchanged, which was the goal of much previous research (e.g., Frey, SchulzHardt, & Stahlberg, 1996;Larson et al, 1994;Parks & Cowlin, 1996;Stasser, Taylor, & Hanna, 1989;Wittenbaum & Stasser, 1996; for a discussion see Reimer & Hoffrage, 2003).…”
