Why do people don't help others when someone is in trouble?
Actually,everyone wants to help the old who's in trouble when in mytro or on the street.But,few people take action.Is that because the city people are shy?In fact,this is oneof the reason.But the
proportion is small.
And there is another psychological reason that we are not willing to help.When many people around us,we may have a feeling that "although i don't help him,others will!"But catually,this is the dependence.Psychologically,the phenomenon is called"Ringlemann effect"
The German psychologist Ringlemann had done a test.He let people to carry a seine.When people increased in joining the group,everyone would not pull vigorously as before.Originally,we supposed that every one would be more vigorous than before when others joined in.But in fact,it was adverse.People would think that:i'm just one of the person in the group".So,they would not pull hard when others joined.
If there are others around,mose people will think"even though i don't help him,others will!"In the real society,many people can't get help when in trouble.And most reason is the result of Ringlemann's psychological effect.
