How group pressure affects individual opinion on a task
Eight male students were arranged around a table as shown by the circles in the image below. Only one of them however was a real participant (shown in blue) the others were confederates of the researchers. The task was to identify which of the lines (A, B or C) was the same length as the test line (X). They answered out loud in turn and the confederates were all told to answer the same incorrect letter. The real participant was placed in his position because it would give him a chance to see what the other participants answers were, but not right at the end as he may become suspicious.
the (genuine) participants conformed on 32% of the trials and only 26% of people never conformed.
Bean counters unite!– Jesness study of conformity around an ambiguous task
Participants guessed at the number of beans in the jar before joining groups and comparing estimations. Jenness found that participants guess at the answer, but when put into groups their answers start to converge around a similar estimate as individuals look to others for help. Unsure of the answer they look to others for guidance and support
24 volunteer college students at Stanford University were divided into “prisoner” and “guard” groups. Over several days the guards became more humiliating and abusive and prisoners became more rebellious, eventually reaching dangerous stress proportions. The experiment was discontinued when the effect were finally noted.
Overview of GroupThink
Advantages of Cohesion

Group Think: Eight symptoms of decreased decision making effectiveness
Counter-measures: Internal and external procedures to monitor team processes and decisions in order to reduce the risk of groupthink and promote effective decision atmosphere
Consequences of GroupThink--faulty decisions
1. Fail to adequately determine their objectives and alternatives
2. Fail to adequately assess the risks associated with group decisions
3. Fail to cycle through discarded alternatives to reexamine their worth after a majority of the group discarded the alternative
4. Not seek expert advice
5. Select and use only information that supports their position and conclusions
6. Does not make contingency plans in case their decision and resulting actions fail
