Couple this effect with groupthink, which is when people simply agree to keep the status quo, and it's clear that group decision making won't always prove superior to flying solo. Groupthink came into play in experiments where four or more people were involved in the process. Groups of two equally-matched subjects with unlimited time to converse and reaffirm one another, and who were honest in their self-assessments, always outperformed individuals in the visual recognition experiments. When one member had worse vision, performance went down significantly. When one partner was secluded and given decision-making autonomy, and had only answer input from the other member, they also performed worse. This indicates that the back and forth exchange of ideas is key to successful group decision making. In cases where participants are honest and communicate openly, two heads are better than one.
