TheTruthAboutMoviePopcorn

ArtSilvermanstaredatabagofmoviepopcorn.Itlookedoutofplace sittingonhisdesk.Hisofficehadlongsincefilledupwithfake-butter fumes.Silvermanknew,becauseofhisorganization’sresearch,that thepopcornonhisdeskwasunhealthy.Shockinglyunhealthy,in fact.Hisjobwastofigureoutawaytocommunicatethismessageto theunsuspectingmoviegoersofAmerica.

SilvermanworkedfortheCenterforScienceinthePublicInterest(CSPI),anonprofitgroupthateducatesthepublicaboutnutrition.TheCSPIsentbagsofmoviepopcornfromadozentheatersin threemajorcitiestoalabfornutritionalanalysis.Theresultssurprisedeveryone.

TheUnitedStatesDepartmentofAgriculture(USDA)recommendsthatanormaldietcontainnomorethan20gramsofsaturated fateachday.Accordingtothelabresults,thetypicalbagofpopcorn had37grams.

Theculpritwascoconutoil,whichtheatersusedtopoptheirpopcorn.Coconutoilhadsomebigadvantagesoverotheroils.Itgavethe popcornanice, silky texture, and released a more pleasant and naturalaromathanthealternativeoils.Unfortunately,asthelabresults showed,coconutoilwasalsobrimmingwithsaturatedfat.

ThesingleservingofpopcornonSilverman’sdesk—asnack someonemightscarfdownbetweenmeals—hadnearlytwodays’ worthofsaturatedfat.Andthose37gramsofsaturatedfatwere packedintoa medium-sizedservingofpopcorn.Nodoubtadecentsizedbucketcouldhaveclearedtripledigits.

Thechallenge,Silvermanrealized,wasthatfewpeopleknow what“37gramsofsaturatedfat”means.Mostofusdon’tmemorize theUSDA’sdailynutritionrecommendations.Is37gramsgoodor bad?Andevenifwehaveanintuitionthatit’sbad,we’dwonderifit was“badbad”(likecigarettes)or“normalbad”(likeacookieora milkshake).

Eventhephrase“37gramsofsaturatedfat”byitselfwasenoughto causemostpeople’seyestoglazeover.“Saturatedfathaszeroappeal,”Silvermansays.“It’sdry,it’sacademic,whocares?”

Silvermancouldhavecreatedsomekindofvisualcomparison— perhapsanadvertisementcomparingtheamountofsaturatedfatin thepopcornwiththeUSDA’srecommendeddailyallowance.Think ofabargraph,withoneofthebarsstretchingtwiceashighasthe other.

Butthatwastooscientificsomehow.Toorational.Theamountof fatinthispopcornwas,insomesense,notrational.Itwasludicrous. TheCSPIneededawaytoshapethemessageinawaythatfullycommunicatedthisludicrousness.

Silvermancameupwithasolution.

CSPIcalledapressconferenceonSeptember27,1992.Here’s themessageitpresented:“Amedium-sized‘butter’popcornata typicalneighborhoodmovietheatercontainsmoreartery-cloggingfat thanabacon-and-eggsbreakfast,aBigMacandfriesforlunch,anda steakdinnerwithallthetrimmings—combined!”

ThefolksatCSPIdidn’tneglectthevisuals—theylaidoutthefull buffetofgreasyfoodforthetelevisioncameras.Anentireday’sworth ofunhealthyeating,displayedonatable.Allthatsaturatedfat— stuffedintoasinglebagofpopcorn.

Thestorywasanimmediatesensation,featuredonCBS,NBC, ABC,andCNN.Itmadethefrontpagesof USAToday, the LosAngelesTimes, and TheWashingtonPost’sStylesection.LenoandLettermancrackedjokesaboutfat-soakedpopcorn,andheadlinewriters trottedoutsomedoozies:“PopcornGetsan‘R’Rating,”“Lights,Action,Cholesterol!”“TheaterPopcornisDoubleFeatureofFat.”

Theideastuck.Moviegoers,repulsedbythesefindings,avoided popcornindroves.Salesplunged.Theservicestaffatmoviehouses grewaccustomedtofieldingquestionsaboutwhetherthepopcorn

waspoppedinthe“bad”oil.Soonafter,mostofthenation’sbiggesttheaterchains—includingUnitedArtists,AMC,andLoews— announcedthattheywouldstopusingcoconutoil.

Thisisanideasuccessstory.Evenbetter,it’sa truthful ideasuccess story.ThepeopleatCSPIknewsomethingabouttheworldthatthey neededtoshare.Theyfiguredoutawaytocommunicatetheideaso thatpeoplewouldlistenandcare.Andtheideastuck—justlikethe KidneyHeisttale.

And,let’sbehonest,theoddswerestackedagainsttheCSPI.The “moviepopcornisfatty”storylackstheluridappealofanorganthievinggang.Noonewokeupinanoil-filledbathtub.Thestory wasn’tsensational,anditwasn’tevenparticularlyentertaining.Furthermore,therewasnonaturalconstituencyforthenews—fewofus makeaneffortto“stayuptodatewithpopcornnews.”Therewere nocelebrities,models,oradorablepetsinvolved.

Inshort,thepopcornideawasalotliketheideasthatmostofus trafficineveryday—ideasthatareinterestingbutnotsensational, truthfulbutnotmind-blowing,importantbutnot“life-or-death.”Unlessyou’reinadvertisingorpublicrelations,youprobablydon’thave manyresourcestobackyourideas.Youdon’thaveamultimilliondollaradbudgetorateamofprofessionalspinners.Yourideasneed tostandontheirownmerits.

Wewrotethisbooktohelpyoumakeyourideasstick.By“stick,” wemeanthatyourideasareunderstoodandremembered,andhave alastingimpact—theychangeyouraudience’sopinionsorbehavior.

Atthispoint,it’sworthaskingwhyyou’d need tomakeyourideas stick.Afterall,thevastmajorityofourdailycommunicationdoesn’t requirestickiness.“Passthegravy”doesn’thavetobememorable. Whenwetellourfriendsaboutourrelationshipproblems,we’renot tryingtohavea“lastingimpact.”

WhoSpoiledHalloween?

PRINCIPLE2:UNEXPECTEDNESS

Howdowegetouraudiencetopayattentiontoourideas,andhowdo wemaintaintheirinterestwhenweneedtimetogettheideasacross?

PRINCIPLE3:CONCRETENESS

Howdowemakeourideasclear?Wemustexplainourideasin termsofhumanactions,intermsofsensoryinformation.Thisis wheresomuchbusinesscommunicationgoesawry.Missionstatements,synergies,strategies,visions—theyareoftenambiguousto thepointofbeingmeaningless.Naturallystickyideasarefullofconcreteimages—ice-filledbathtubs,appleswithrazors—becauseour brainsarewiredtorememberconcretedata.Inproverbs,abstract truthsareoftenencodedinconcretelanguage:“Abirdinhandis worthtwointhebush.”Speakingconcretelyistheonlywaytoensurethatourideawillmeanthesamethingtoeveryoneinouraudience.
