Information Sharing Intensity and Decision Quality. Hypothesis 3 predicted that group decision-making quality was positively related to the intensity of information sharing. The results of the regression analysis indicated that the information sampling rate received a significant weight in predicting group decision making quality, β 5 0.41, t 5 3.07, p < .01. H3a was verified. However, the regression weight of information repetition rate on group decision making quality was not significant, β 5 0.10, t 5 0.65, p 5 .52. H3b was not supported. Thus, H3 was partially supported.

N2 - Prior research has discovered that groups tend to discuss shared information while failing to discuss unique information in decision-making processes. In our study, we conducted a lab experiment to examine the effect of prediscussion note-taking on this phenomenon. The experiment used a murder-mystery hidden profile task. In all, 192 undergraduate students were recruited and randomly assigned into 48 four-person groups with gender being the matching variable (i.e., each group consisted of four same-gender participants). During the decision-making processes, some groups were asked to take notes while reading task materials and had their notes available in the following group discussion, while the other groups were not given this opportunity. Our analysis results suggest that (a) the presence of an information piece in group members' notes positively correlates with its appearance in the subsequent discussion and note-taking positively affects the group's information repetition rate; (b) group decision quality positively correlates with the group's information sampling rate and negatively correlates with the group's information sampling/repetition bias; and (c) gender has no statistically significant moderating effect on the relationship between note-taking and information sharing. These results imply that prediscussion note-taking could facilitate information sharing but could not alleviate the biased information pooling in hidden profile tasks.
