process loss: aspects of group interaction inhibit good problem solving
- failure to share unique info, group polarization, groupthink

failure to share unique info: groups tend to repeat info over and over again, no new individual info

- ex celebrities sharing info about how to avoid paparazzi pics

ex 3 person team of physicians in hypothetical medical scenario (shared info discussed more than unshared info) (Larson, 1998)
- the doctors won't share their individual knowledge of the patient, they'll end up discussing the common symptoms they all know about the patient

group polarization:
- tendency for groups to make decisions that are more extreme than initial inclinations of group members
- can be cautious or risky

ex. asking friends/family for estimates of Canucks winning stanley cup this year, as a group collectively they make a more extreme decision of 80% chances compared to their initial individual estimates

- kind of thinking in which maintaining group cohesiveness and solidarity is more important than considering facts in a realistic manner

most likely to occur:
- highly cohesive group
- isolated from other opinions
- directive leader who makes opinions known

can make group feel invulnerable, won't risk defiance > make inferior decisions

ex. Simpsons w Mr Burns as leader, his followers are yes men to all of his decisions, leading to him losing all of his money
