ClassicalInterpretation

Thecompositionofasubjecthasthreeaspects:historicaltheoryandapplication.Communicationisacross-disciplinedevelopedfromtheUnitedStatesinthe1920sand1930s,anditsmainresearchobjectistheinformationdisseminationofhumansociety.Affectedbytheglobaltrendofinformationdissemination,communicationhasbecomeoneofthefastest-growingdisciplinesintheworld.FromalargenumberoforiginalEnglishworksofcommunicationstudiesinforeignlibraries,theauthorselected10classicworksrespectedbytheacademiccircle,withoutpresumption,comprehensivelyinterpretingtheresultsofpreviousstudies,andrecommendingthemtoChinesereaders.

Lippmanisoneofthemostinfluentialscholarsinthehistoryofcommunication,andenjoysahighreputationinpropagandaanalysisandpublicopinionresearch.Themostfamouspoliticalcolumnistintheworld,inhis1922book"PublicOpinion",pioneeredtheearlyideastodaycalledagendasetting.Thisbookisrecognizedasafoundationalworkinthefieldofcommunication.

Asaclassicworkoncommunication,thisbookprovidesapanoramicdescriptionofpublicopinionforthefirsttime,allowingreaderstoexperiencetheinternalandexternalconnectionsofpublicopinionindetail.Sinceitspublicationin1922,thisbookhasbeentranslatedintodozensoflanguages​​indecades,anditstillmaintainsanauthoritativepositioninthisfield.

ThesecretoftheenduringinfluenceofLippmann's"PublicOpinion"isthatthebookhaseffectivelysortedoutaseriesofunavoidableproblemsinpublicopinionresearch,suchaswhereandhowpublicopinioncomesfrom.Forming?Whatkindofresultscanitcause?Whoisthepublicandwhatkindofpublic?Whatdoespublicopinionmean?Isitonlyspreadamongthepublicorisitformedbythepublicthemselves?Isitorwhenwillitbecomeanindependentforce?

Inmodernsociety,publicopinionismainlyregardedasapoliticalphenomenon.Itcanbesaidthattherehaveonlybeentwosources,namely,anopenpublicopiniongenerationandcirculationsystemandaclosedpublicopinionproductionandindoctrinationsystem.Theyallproduceapublicopinionprocessofsimilarcomplexity,buttheresultsarenotthesame.Lippmann’s"PublicOpinion"hasmadeincisiveandin-depthdiscussionsonissuessuchasstereotypes,interest,theformationofpublicwill,andtheimageofdemocracy.Ithascompletedthefirstcomprehensivereviewofthespreadofpublicopinioninthehistoryofnews,andisagreatopportunityforfuturegenerations.Theresearchlaidthefoundation.

Lippmanhaslongnoticedthehugeimpactofmasscommunicationonsociety.Therefore,inworkssuchas"PublicOpinion"and"FreedomandNews",itisnotonlyaboutthenatureofnewsanditsselectionprocessAdeepanalysiswascarriedoutandtwoimportantconceptswereputforward,oneis"pseudoenvironment";theotheris"stereotype".Lipmanbelievesthatmodernsocietyisbecominglargerandmorecomplex.Duetothelimitedscope,energyandattentionofactualactivities,itisimpossibleforpeopletomaintainempiricalcontactwiththeentireexternalenvironmentandmanythingsrelatedtothem.Forthingsbeyondtheirownpersonalperception,peoplecanonlyunderstandcognitionthroughvarious"newssupplyagencies".Inthisway,humanbehaviorisnolongeraresponsetotheobjectiveenvironmentanditschanges,butaresponsetoacertain"mimeenvironment"promptedbynewsorganizations.

Theso-called"mimeenvironment"isnota"mirror"representationoftherealenvironment,butanenvironmentthatthemediaremindspeopleafterselectingandprocessingsymboliceventsorinformation,andrestructuringthem.However,becausethiskindofprocessing,selection,andstructuringactivitiesarecarriedoutinplacesthatareinvisibletoordinarypeople(insidethemedia),peopleusuallydonotrealizethis,andoftentreatthe"mimeenvironment"astheobjectiveenvironmentitself.

And"stereotype"referstopeople'sfixedandsimplisticideasandimpressionsofaparticularthing,whichisusuallyaccompaniedbyevaluationofthevalueofthethingandfeelingsoflikesanddislikes.Stereotypescanprovideasimplereferencestandardforpeopletounderstandthings,buttheyalsohindertheacceptanceofnewthings.Individualshavepersonalstereotypes,andasocietyalsohasstereotypesthatarewidelyacceptedandprevailingbyitsmembersofsociety,soitalsoplaysacontrollingroleinsociety.Lipmanparticularlyemphasizesthepowerofmasscommunication,andbelievesthatmasscommunicationisnotonlythemaincreatorofthe"mimeenvironment",butalsohasastronginfluenceinforming,maintainingandchangingthestereotypesofasociety.

Inaddition,theresearchonagendasettingalsobeganinLippman’s"PublicOpinion".Althoughthetermagendasettingisnotusedinthebook,heexpressedthebasicidea:mediacreationInadditiontothesymbolicimaginationsinourminds,theseimaginationsmaybecompletelydifferentfromthe"outer"worldweexperience.Hearguedthatmassmediaisthemainlinkbetweenaneventintherealworldandourimaginationofthisevent.Theagendasettingprocessdescribeshowpublicopinionplaysaroleinademocracy.40yearslater,Cohencontinuedtocontributetothedevelopmentofagendasetting.Hepointedoutthatthepresshasnotbeenverysuccessfulintellingpeople"howtothink",butitisextremelyeffectiveintellingpeople"whattothink".Ofcourse,itwasn'tuntil1972thatMcComsandShaw'sarticlewaspublishedinthe"QuarterlyJournalofPublicOpinion"thattheagendasettingwasnamed.Asoneofthefirstscholarswhodiscussedthemacroeffectsofmasscommunication,Lipmanmadeagreatcontributiontothegenerationanddevelopmentofthistheory.Hisclassicwork"PublicOpinion"hasalsoenduredforalongtimebecauseoftheincisivediscussionoftheabove-mentionedcommunicationissues.
