When people think of a group getting together to make a decision, a common perception is that group discussion enables the members to pool their diverse knowledge together so the group makes a more informed decision than individuals. Contrary to this common belief, group members tend to pool and discuss common information while leaving unique information behind. As a result of this information pooling phenomenon, the correct decision that requires the group to pool together the unique information together cannot be identified by the group, hence is called the "hidden profile". Virtual group decision-making activities are more vulnerable to the hidden profiles problem because of its leaner communication media compared to face-to-face groups. The proposed research attempts to address the hidden profiles problem in virtual group decision-making by exploring the value of sharing and visualizing group members' rationales in a virtual hidden profile task. Specifically, two collaborative applications will be designed and implemented to provide the collaborative visualization of the shared rationales, using two visualization mechanisms, namely, author-based and information-based mechanisms. The effectiveness of the visualization techniques will be examined through a lab controlled study where virtual groups will conduct a hidden profile task under three conditions: Instant Messenger (IM) only, IM + the collaborative application with author-based visualization mechanism, and IM + collaborative application with information-based visualization mechanism. The collaborative applications developed in this research will be made accessible to groupware researchers and public. While in the short term, the research will focus on the value of sharing and visualizing the group members' rationales in addressing the hidden profiles problem, future research will look at the their value in virtual group's knowledge building, knowledge management, and collective intelligence.

当人们想到一个团体聚在一起做出决定时，普遍的看法是团体讨论使成员能够将不同的知识集中在一起，从而使团体比个人做出更明智的决定。与这种普遍看法相反，小组成员倾向于汇集和讨论共同信息，同时留下独特的信息。由于这种信息汇集现象，需要群体将独特信息汇集在一起​​的正确决策无法被群体识别，因此被称为“隐藏档案”。虚拟群体决策活动更容易受到隐藏档案问题的影响，因为与面对面群体相比，其沟通媒介更为精简。所提出的研究试图通过探索虚拟隐藏个人资料任务中共享和可视化小组成员的基本原理的价值来解决虚拟群体决策中的隐藏个人资料问题。具体来说，将设计和实现两个协作应用程序，以使用两种可视化机制（即基于作者的机制和基于信息的机制）提供共享原理的协作可视化。可视化技术的有效性将通过实验室控制的研究来检验，其中虚拟小组将在三种情况下执行隐藏的个人资料任务：仅即时通讯（IM）、IM +具有基于作者的可视化机制的协作应用程序、以及IM +具有基于信息的可视化机制的协作应用程序。本研究中开发的协作应用程序将可供群件研究人员和公众使用。虽然在短期内，研究将重点关注共享和可视化小组成员在解决隐藏档案问题中的基本原理的价值，但未来的研究将着眼于它们在虚拟小组的知识构建、知识管理和集体智慧中的价值。
