AbstractNationalsurveysconductedin2010and2012suggestthefollowingconclusions:

‐ AmericanunderstandingofwhatisandisnotintheACAhasbeenfarfromperfect.

‐ Correctunderstandingoftheelementsofthebillweexaminedvariedwithpartyidentification:Democratsunderstoodthemost,independentsless,andRepublicansstillless.

‐ Olderpeopleandmoreeducatedpeoplehaveunderstoodtheelementsofthebillweexaminedbetterthanhaveyoungerandlesseducatedpeople.

‐ Between2010and2012,publicunderstandingoftheelementsofthebillweexamined

didnotchangenotably.‐ MostpeoplehavefavoredmostoftheelementsoftheACAthatweexamined,butnot

everyonerecognizedthattheseelementswereallintheplan.‐ Mostpeopleopposedpoliciesthatweresometimesfalselythoughttobepartsofthe

IntroductionThePatientProtectionandAffordableCareActof2010(ACA)enactedaseriesofsignificantchangestotheAmericanhealthcaresystem.The900‐page‐longbill,whichelicitedanextremelypartisanreactionandsubstantialnewsmediainterest,amendedtheU.S.codetopreventinsurancecompaniesfromdenyingcoverageforpre‐existingconditions,provideforhealthcareexchangeswhereindividualscouldpurchasecaredirectly,requireallindividualstohavehealthinsuranceorpayafine,andmore.InJune,2012,theU.S.SupremeCourtupheldacentralelementofthislaw.

PublicdebateaboutthebillcalledattentiontomanyaspectsofthelawthatwereincludedintheversionthatCongressapproved.Butduringthecourseofpublicdebate,anumberofinaccurateclaimsweremade,assertingthatthebillincludedprovisionsthatwerenotincludedinthefinalversion.Someofthewidelydiscussedcomponentswerepartofthelegislation,suchastheplantoallowchildrentostayontheirparents’healthplanthroughage26.Butotherwidelydiscussednotionswereneverconsideredforinclusion,suchastheclaimthatapanelofbureaucratscoulddecidewhencoveragewouldbegiven(theso‐called“deathpanels”).Thelegislationincludedavarietyofless‐oftendiscussedprovisions,suchaschargingafeetoinsurancecompaniesthatofferedparticulartypesofinsurance.

Manysurveyswereconductedbothbeforethebill’spassageandafteritsenactmenttogaugetheAmericanpublic’sreactiontoit.Inearly2010,publicopinionwasfairlyevenlysplit.Forexample,accordingtoaKaiserFamilyFoundation(KFF)surveyinAprilofthatyear,46%ofAmericanssaidtheyhadafavorableopinionofthebill,and40%saidtheyhadanunfavorableopinion.Ayearlater,inApril2011,KFFreportedthesetwostatisticstobe41%and41%,respectively.AndinJanuary2012,thefigureswere37%and44%,respectively,perhapssuggestingaslightshiftintheunfavorabledirectionastimehaspassed.InMay2012,thefigureswereidentical:37%and44%,solidifyingevidenceofthatslightshift.AndinAugust2012,thesefigureswere38%and43%,respectively.

AsimilarportraitwaspaintedbyAP‐GfKpolls.InMay,2010,39%ofrespondentssaidtheysupportedtheACA,and46%saidtheyopposedit.InJune,2012,thosenumberswere33%and47%,respectively.Thus,asmalldecreaseintheproportionsupporting,andasmallincreaseintheproportionopposing.

Surveysdonebyotherorganizationsprovidedsimilar,thoughnotidentical,portraitsofthebalanceandtrajectoryofopinions.Forexample,aNBCNews/WallStreetJournalpolldoneinMay,2010,found38%ofrespondentssayingtheythoughttheACAwasagoodidea,and44%saiditwasabadidea.AsofJune,2012,thatorganizationfoundthesefigurestobe35%and41%.Thus,theproportionexpressingapositiveopiniondroppedslightly,liketheKFFpolls.Buttheproportionexpressinganegativeopinionalsodroppedslightly.

Onlyoneprominentnationalsurveyresearchorganization,ThePewResearchCenter,reportedresultssuggestingmovementintheoppositedirection.InJanuary,2011,41%oftheirrespondentsapprovedoftheACA,and48%opposed.Theirmostrecentsurvey,inJune‐July,2012,foundthat47%approved,and43%opposed.

Puttogether,mostnationalsurveysduringthelasttwoyearssupporttwoprincipalconclusions:(1)publicopinionhasnotmanifestedasizableandconsistentleaningtowardbeingfavorableorunfavorabletowardtheACA,and(2)aslightshiftinthenegativedirectionmayhaveoccurredsincethelawwaspassed.

ItwouldbeunderstandabletolookatsuchevidenceasanindicationthattheAmericanpublicdoesnotstronglysupportthispieceoflegislation.Afterall,ifaboutasmanypeoplefavoritasopposeit,andifwehaveneverseenamajorityfavoringit,thathardlysendsastrongsignalofsupport.Furthermore,itiseasytoimaginethatsincepassageofthebill,Americanshavehadtimetoconsiderthebillanditsimplicationsinmoreandmoredepth,andifsuchconsiderationleadstoashiftinthenegativedirection,thatcertainlysignalsquitetheoppositeofenthusiasm.Thus,suchdatacouldbetakenasasignalthatRepublicaneffortstorepealthebillwouldbewarmlywelcomedbyagrowinggroupofAmericans.

Atthesametime,theverysamepollingevidencecanbeviewedfromtheoppositeviewpoint.AlthoughamajorityofAmericanshavenotfavoredthebill,itisalsotruethatamajorityhaveneveropposedit,either.Andevenaftertherecentsmallincreaseinopposition,theproportionopposingitdoesnotexceed50%.Sodirectquestionsaskingaboutpositivevs.negativeevaluationsoftheplanhavenotdocumentedamandatefromthepublictorepealthebill.9Takentogether,allthisevidenceportraystheAmericanpublicinwhatmightseematypicalway:splitaboutevenly,andnotprovidingaclearmandatetoelectedrepresentativesonewayoranother.

Itwouldthereforenotbeunreasonableforthoserepresentativestolookatthispollingevidence,reachthatconclusion,andproceedtotakeactionsinkeepingwiththeguardianshipviewofdemocracy:decidingwhattheyfeelisbestforthecountryandtakingaction(ordoingnothing)accordingly,regardlessofpublicopinion.

Suchignoringofpublicopinionmightalsobejustifiedfromanotherperspectiveaswell.Insomanysurvey‐basedinvestigationsoftheAmericanpublicformanydecades,peoplehavebeenfoundtoperformquitepoorlyonquizzesassessingfactualknowledgeaboutdomainsinwhichsignificantlegislationhasbeenconsideredorpassed.Ifmostpeoplelackthefactsneededtotrulyunderstandtheproblemstobesolvedbyapieceoflegislationandthesolutionsofferedbythatlegislation,whyshouldpublicevaluationsofthelegislationbetakenseriously?Thatis,thepublicmightfeelverydifferentlyiftheytrulyunderstoodabill,soopinionsbasedonpartialinformationorsubstantialmisconceptionscancertainlynotbedescribedas“wise”andshouldperhapsthereforebeignoredbylegislators.

Ofcourse,ignoringpublicopinion,evenuninformedpublicopinion,mayplacelegislatorsatriskcomeelection‐time.Evenwhenthepublicdoesnotunderstandapieceoflegislation,membersoftheelectoratemaynonethelessholdstrongopinionsaboutit,eitherfavorableorunfavorable,andthoseopinionsmayshapetheirvotingdowntheroad.Indeed,agreatdealofresearchsuggeststhatpublicopiniononpolicyissuesdoessometimesshapevotechoices(seeAnand&Krosnick,2003;Krosnick,1988).Soalegislatorwhovotesagainstapieceoflegislationthatvotersfavormay9QuestionsaskingwhetherthebillshouldberepealedhavesometimesshownamajorityofAmericansansweringaffirmatively.

Inasituationsuchasthis,legislatorswhowishtoseeapieceoflegislationpassed(oravoiditsrepeal)alwayshavetheoptionofinformingtheAmericanpublicaboutwhatthelegislationwouldtrulydo,inthehopethatbetterunderstandingwouldleadthepublictoofferastrongersignalofsupporttotheirelectedrepresentatives.Butwouldsucheducationindeedleadtomoresupport?Thispresumablydependsonthenatureofthepublic’smisunderstandingsandonthepublic’sevaluationsoftheelementstheybelievecomposethelegislationandoftheelementsthatinfactcomposeit.

Inthispaper,wereportaninvestigationofexactlytheseissueswithregardtotheACA.Usingdatafromtwosurveys(oneconductedin2010andtheotherin2012),weexplored:

1) HowaccuratelyAmericanshaveunderstoodwhatisintheACAandwhatisnot.2) Howtheaccuracyofpeople’sunderstandinghaschangedduringthetwoyearssincethe

billwaspassed.3) HowknowledgeaccuracyisrelatedtofavoringtheACA–thatis,whetherpeoplewho

knowmoreaboutwhat’sintheACAlikeitmoreorlikeitless,4) HowthepublicwouldfeelabouttheACAifeveryoneunderstoodthataseriesofits

centralelementsareindeedincludedintheACAandthataseriesoffrequentlydiscussedbutultimatelyomittedelementsarenotinit.

Alongtheway,weinvestigatedtwootherissues:

1) Thepredictorsofaccurateunderstandingoftheplan‐thatis,whichtypesofpeoplearemoreandlesslikelytoscorewellonaquiz.

2) Thepopularityofvariousspecificelementsthatwereincludedintheplan,andhowpopularareelementsthatwerenotincludedbutweresometimesclaimedtobe.

Incarryingoutthisinvestigation,weimplementedanewapproachtomeasuringpublicunderstandingofapublicpolicyissue.Insurveysdoneduringthelast80years,ithasbeenroutinetotestknowledgebyaskingpeoplefactualquestionsandgradingpeopleaseithercorrectorincorrectbaseduponwhethertheiranswermatchedthefactsornot.Butthisapproachignoresasimpleandunavoidablefact:thatarespondentsayingtoasurveyinterviewerthatmembersoftheRepublicanPartyoutnumbermembersoftheDemocraticPartyintheU.S.HouseofRepresentativesdoesnotnecessarilymeanthattherespondentbelievesthistobetrue.Whenaskedwhichpartyholdsmoreseats,arespondentmightsimplyguessandendupgivingthecorrectanswerbychancealone.Thisresponsewouldnotrevealabeliefthattherespondentgenuinelyholds,norwouldthatpurportedbeliefhaveanyimpactonhisorherthinking,becauseheorshedoesnottrulyholdthatperceptionoftheworld.Guessingseemslikelytoespeciallydistortanswerstoquizquestionsthatofferonlytworesponsechoices,asweusedhere(isthisincludedintheACAornotincludedintheACA?).

Onemightimaginethatthisproblemcanbeovercomebyexplicitlyofferingsurveyrespondentstheopportunitytodeclinetoanswerasurveyquestionbysayingthey“don’tknow”theanswerandencouragingthemtodoso.Butagreatdealofresearchsuggeststhatthisstrategyisunwise.Insteadofattractingonlyandallofthepeoplewhotrulydonotholdabeliefonanissue.“don’tknow”responseoptionsattractmanyrespondentswhotrulyholdopinionsandfailtoattractrespondentswhoholdopinionswithlittleornocertainty(forareview,seeKrosnick,2002).

Thesolutiontothisproblemissuggestedinsteadbyaliteratureinpsychologyoncertainty.Theintendedpurposeofofferinga“don’tknow”optionistypicallyexpressedasfilteringoutpeoplewhowouldexpressajudgmentwithnocertaintyatall.Thatis,apersonmightsay“IthinkthattheDemocratsholdmoreseats,butI’mnotatallconfidentaboutthatguess.”Thus,thepreferablesolutionistofirstaskpeopletomaketheirbestguessandthentoaskthemtoratethecertaintywithwhichtheyexpressthatbelief.Thisallowsresearcherstofilteroutpeoplewhoofferopinionswithlittleornocertainty.

Acollateralbenefitofthisapproachisthatcertaintystronglycorrelateswithuseofbeliefsduringdecision‐making.Peoplewhoholdabeliefwithconfidenceareinclinedtouseitwhenmakinghighlyrelevantdecisions.Incontrast,peoplewhoholdabeliefwithminimalconfidenceareunlikelytouseit(forareview,seePetty&Krosnick,1995).Thus,givingsurveyrespondents“credit”foraccuratelypossessingabeliefonlywhentheyexpresshighcertaintyallowsustoidentifythosebeliefsthatarealsolikelytohaveshapedpeople’soverallevaluationsoftheACA.

Therefore,inkeepingwiththisperspective,whenweadministeredquizquestionsassessingpublicunderstandingoftheACA,eachquestionwasfollowedbyaquestionaskingrespondentshowsuretheywereabouttheiranswertothepriorquestion.Peoplewhoexpressedhighdegreesofconfidencewhengivingacorrectanswerweretreatedasholdinganaccuratebelief,andpeoplewhogaveacorrectanswerwhileexpressedlowdegreesofconfidencewerenotcreditedashavinganaccuratebelief,norwerepeoplewhoansweredthequizquestionsincorrectly.

TheelementsoftheACAthatwereaddressedbythequizquestionswereselectedcarefullytocovermostofthecentralelementsoftheplan.Intheirdocumententitled“FocusonHealthReform:SummaryofNewHealthReformLaw”(Publication#8061;www.kff.org),theKaiserFamilyFoundationprovidedwhattheycalleda“summaryofthelawandchangesmadetothelawbysubsequentlegislation.”WereliedonthissummarytoselecttheelementsoftheACAtoaskaboutinoursurvey.WealsoaskedaboutanadditionalsetofpoliciesthatwerenotultimatelyincludedintheACAbutwerediscussedduringthepublicdebateofit.

Results

Favoringvs.OpposingtheACAin2012In2012,32%ofrespondentssaidtheyfavoredtheACA,36%saidtheyopposedit,and32%saidtheyneitherfavorednoropposedit.Thefactthatnegativeresponsesslightlyoutnumberedpositiveresponsesresemblesresultsproducedbyvariousotherpollingorganizationsinrecentmonths.

Notsurprisingly,evaluationsofthebillvariedaccordingtopoliticalpartyidentification.AmongDemocrats,51%favorthebill;29%ofindependentsexpressedthesameopinion,and8%ofRepublicansdidso.Thepartisangapof43percentagepointsisnotatypicalinAmericanevaluationsofpiecesoflegislationthesedays.
