PSY 530 Module 6 DQ 1: Groupthink and Helping

Keep the two concepts genuinely separate, because they are often conflated and they predict different things. Groupthink is a failure of process: a cohesive group under a directive leader, insulated from outside input and facing perceived threat, converges prematurely on a decision and suppresses dissent, producing symptoms such as an illusion of unanimity, self-censorship and self-appointed mindguards. Group polarization is a shift in position: discussion among people who already lean the same way moves the group average further in that direction, through exposure to novel supporting arguments and through social comparison as members position themselves relative to the group's ideal. The conditions differ accordingly — groupthink needs cohesion, insulation, a directive leader and stress, while polarization needs only initial homogeneity and discussion. Note that cohesion is doing double duty here: it is what makes the group effective and what makes dissent expensive. Say which antecedents you consider necessary rather than merely common.

The third question is the application and it is where the post earns its marks. Consider an institution deciding how to respond to a population in need. Polarization predicts that a committee whose members start mildly sceptical about deservingness will end more sceptical than any individual began, with no new information involved. Groupthink predicts that once a decision forms, the member who thinks the group is being unjust will read the room and say nothing, so the decision looks unanimous when it never was. Layer on diffusion of responsibility, which explains why a group can identify a need clearly and still assign it to nobody. Then say what would counter each: designated dissent and outside input for groupthink, deliberate viewpoint diversity for polarization, and named ownership for diffusion. Matching each countermeasure to its own mechanism is what shows the concepts were understood rather than recited.
