Individual, group and team behaviour

2.4 Problems with groups
Unfortunately groups can also have negative as well as positive effects:

 Conformity. Individuals can be persuaded by group pressures to
agree with decisions which are obviously wrong, and which the person
must know to be wrong.

 The Abilene paradox. This is a famous case, which demonstrates
that the group can end up with an outcome that none of the members
wanted.

 ‘Risky shift’ or group polarisation. This is the tendency for groups to
take decisions which are riskier than any that the individual members
would take on their own.

 Groupthink. This occurs within deeply cohesive groups where the
members try to minimise conflict and reach consensus without
critically testing, analysing, and evaluating ideas.
