An intervention that might exacerbate the common information effect is:

A) approaching the task as a problem to be solved,not a judgment to be made.
B) ranking rather than choosing.
C) suspending initial judgment.
D) prediscussion polling.

Prediscussion polling, which involves asking group members to share their initial opinions or preferences before discussing the topic, can exacerbate the common information effect by increasing the likelihood of group members conforming to the majority opinion. This can lead to a narrowing of perspectives and a lack of consideration of diverse viewpoints. Thus, choosing D is the best answer as it is the option that is most likely to exacerbate the common information effect.
