例如，群體思維和群體轉移等現象可能會阻礙群體通過客觀地評估備選方案來做出高質量決策的能力。根據(Robbins, Millett， & Waters-Marsh, 2004)，群體思維與群體規范相關。它描述了群體之間的壓力可能會消除不尋常的、少數的或不受歡迎的觀點在決策時的評估。群體轉移是一種情況，當群體做出決定時，他們可能會做出更冒險的決定，因為成員最初的立場被夸大到更極端的立場。此外(Robbins, Millett， & Waters-Marsh, 2004)已經確定了許多可能影響群體表現的因素，而不是作者通過她的10個關鍵特征確定的群體動力學。群體的規模、群體執行資源的可獲得性、社會游手好閑等都會對群體的結果產生很大的影響。從前面提到的缺點來看，很明顯，群體思維現象可能與她在文章中提到的凝聚力特質相矛盾。她曾提到，凝聚力是表現中的一個重要動力。沒有凝聚力，一個團隊就會分崩離析。但是她沒有提到凝聚力的限制，因為正如前面提到的，極度的凝聚力會導致群體思維，最終影響群體的有效決策。
For an example phenomenon like groupthink and groupshift that could hinder the ability of the group to come into quality decisions by evaluating alternatives objectively. According to (Robbins, Millett, & Waters-Marsh, 2004) groupthink is related to the group norms. It describes that with the pressure from group to conformity group may eliminate unusual, minority or unpopular views from evaluating when making decision. Groupshift is a situation where when group arriving at a decision they could go for more risky decision as members initial positions are exaggerated toward more extreme positions.Further (Robbins, Millett, & Waters-Marsh, 2004) has identified many factors that could affect group performances than the group dynamics that have been identified by the author of the article through her 10 critical traits. Size of the group, availability of resources for a group to perform, effects of social loafing, etc. could affect the outcome of groups greatly.From the shortcomings mentioned earlier it is clear that the phenomenon of groupthink could clearly contradict with cohesiveness trait that she has mentioned in the article. She has mentioned that cohesiveness as an important dynamic in performance. Without cohesiveness a group can fall apart. But she has failed to mention the limit of cohesiveness because as mentioned earlier, extreme cohesiveness can cause groupthink and ultimately affect the effective decision making in the group.
