Lippmann who was a famous writer in press circle of America and is respected by many reporter in the different nations, publiced a book on 1920s,which was named Public opinion .There was a important theory in this book to describe that what reflection you see someone frist,which was defined as stereotype.It means when we see someone at first ,we will impressive of his trait,his personality and judge him by our experience and values.I think it exist and effect on someone in some way.But,sometimes it is wrong that you see something or hear someting frist to make a conclusion instantly .
Firstly,it is right for this old saying that is 'Seeing is not necessarily true".we maybe only see the surface of something.After all,the fact touched by us maybe a part of the true things,we cannot know everything because we didnot work or live with him,we absent on the spot.Secondly,our vision and knowledge is limited.we cannot deep into someone's heart to conversion openly unless we make friends with him and live with him for a long time.So if we just is to contact as ordinary friend or colleague ,we have no idea to judge him rightly because everyone wear musk on his face in the social occasion.For the things that we heared,we have no right to measure it is good or bad.we are far away the truth.At last,it looks like so irresponsible to judge the things instantly.When we want to confirm a man or things we should make a conclusion after knowing all aspects. Otherwise we maybe make a mistake for a man or something to destory his life or make the things becoming worst.
In a word,it is wrong that you see something or hear someting frist to make a conclusion.so we shouldnot depend on our idea to measure.
