The short-term of the theory is the methods of the group, which occurs when there is pressure to follow the resolution.By the group thinking is a phenomenon caused by the psychological pressure that occurs when a members of group work are more closely together and even have the same values and beliefs when faced with a stressful situation it causes the symptoms of thought.For example,the manager said ,“ I had distinct feeling that we were in the position of having to prove that we were in the position of having to prove that it was unsafe in stead of the other way around”. The member will believe on the manager's thought and make symptoms of groupthink.So,I claim that the short-term is members use a little consideration in order to make decision follow the manager.
