What does the following example from social psychology illustrate? a group engages in an active discussion regarding plans for the weekend. throughout this discussion, it is decided that a subgroup of members of the group have a strong position that the group should agree to a trip out of town. other members of the group are not so sure and suggest planning an event close to home. as the discussion continues, members of the two subgroups become more fixed on everyone choosing their plan and are less willing to consider the alternative choice.
