One of the dangers of groupthink is the group's tendency to: Group of answer choices a) overthink all their possible options and delay the decision-making process. b) come up with too many solutions to a problem in an effort to reflect the unique knowledge of each of its members. c) be unable to come up with a solution due to the bystander effect. d) sacrifice the soundness of a decision in order to achieve interpersonal harmony.

Answer: D) Sacrifice the soundness of a decision in order to achieve interpersonal harmony

Explanation: Group thinking involves more and more diverse suggestions for solving a problem, as there are multiple different attitudes and views within the group. It can also mean many different possible solutions, so the option to choose the best ones. There may also be a situation where the objective best solution is often not chosen in order to reach a compromise among the members of the group, because in the group one must always count on vanities and egos. It can also lead to slow and often ineffective decision making until all the solutions offered are reviewed. However, the worst-case scenario is to intentionally sacrifice the right solution for the sake of interpersonal harmony. This means that the group essentially did not meet to find the best solution, but to treat the excessive vanities and egos of its members.
