Groupthink
One process by which groups may make bad or irrational decisions is known as groupthink. Individual members of a group attempt to conform their opinions to what they believe to be the group consensus even though the result may be negative. There are many reasons why groupthink happens. These include the desire to be liked, fear of losing a job, or even not wanting to be the one employee delaying a decision that seems inevitable. These kinds of implicit pressures to conform lead group members to ultimately make decisions that each, by himself or herself, might normally not make.
