3.ThePowerofWords:AdvertisingTricks

Theeffectthatwordscanhaveisincredible:toinform,persuade,hurtoreasepain,endwarorstartonekillingthousandsorevenmillionsofpeople.Theycangetyourpointacross,ordestroyanyhopeofyourideaseverbeingunderstood.Amajorelementofadvertisingisthewords,whichonesandinwhatorder.Thefollowingisseveralofthespecifictricksthatarecommonlyusedinadvertising.

Black/WhiteTrick

Theblack/white,oreither/or,trickismakingastatementthatprovidesinsufficientoptionstoyourargument."Loveitorleaveit"wasabigsloganofthe1960s,anditsoundslogical.Nevertheless,itprovidesnootherpossibleoptions,suchas"Loveit,ordon'tloveit,stayornot,youdon'thavetoagreewithmeifyoudon'twantto."

Thereasonthisfallacyisoftencalledtheblack/whitefallacyisthatitdeniesanyotherchoicesonanissueoridea.Usingitgivestheimpressionthateverythingcanbeseenintermsofyesorno,trueorfalse,onoroff,withnomaybesorbothtrueandfalsedependingoncircumstancesallowed.Thisfallacyisparticularlypopularandeffectiveinsloganslike"Loveitorleaveit","Ifyou'renotforme,you'reagainstme","Mycountry,rightorwrong".Notethatalloftheaboveactuallyhaveotheroptions,butthestatementsdonotallowforthem.

Acommonwayinwhichthistrickisusedinadvertisingisbypresentingtwosituations,onewiththeproductand'theotherwithout.Theonewiththeproductshowscircumstancesthattheadvertiserpresumesthetargetaudiencewouldliketobein,andviceversaforthesituationwithouttheproduct.Forexample,youhavetwogroupsofpeople:thefirstisyoung,beautiful,fit,happy,fun-lovingandactive;thesecondisold,ugly,miserable,andpassive.Thefirstusestheproduct;theseconddoesn't.Theassumptionisthatthepurchaseoftheproductmakesyouamemberofthefirst,thattheabsenceoftheproductmakesyouthesecond.Sincemostpeoplewouldratherbethefirst,andtheproductisapartofbeingthefirst,thenpeopleshouldbuytheproduct.Andtheydo.

GeneticFallacy

Thegeneticfallacymakesapredictionaboutsomethingbasedonwhereitcamefromoritsorigins.Forexample,saying"Hewouldn'tdothat--he'sfromagoodfamily"ismakingageneticfallacy."Youcan'texpectanybetterfromher--she'sfromtheslums"isalsousingageneticfallacy.Notethatinneithercaseisthereanyreferencetotheindividual'spersonalabilitiesorlackthereof;onlytowheretheycamefrom.Inadvertising,thisfallacyisusedoften:"Ifit'smadeby[company],itmustbegood"isanexample.

Weasel(含糊其辞的)Words

Weaselwordsarethosewordsthataretossedintoasentencethatchangetheactualmeaningofthesentencewhileleavinganimpressionthatisdifferent.It'stheeasiestwaytoavoidhavingtotakeanyresponsibilityforanythingyousay,orseemtosay.Forexample,thesentence"Ourcannedcornisasgoodasfreshcookedcorn".Theimpressiongivenisthatthecannedcornisasgood(whateverthatmeans)ascornonthecob(玉米穗轴)rightoffthestalk.However,thephrasecontainsaweaselword:"cooked".Thus,thesentenceactuallysaysthatthecannedcornisasgoodascornthathasbeencooked;nowyouneedtocookitagaintoserveit.Notethesentencedoesnotsaythatthecannedcornisasgoodasfreshcorn;it'sasgoodasfreshcookedcorn.

Afavoriteweaselwordisoneoftheshortest:if."Ifthewholewideworldcanenjoy[use,buy,desire,etc.][whatevertheproductis],thensocanyou"saysabsolutelynothingabouttheproduct,orevenifanyoneatallenjoys[uses,buys,desires,etc.]theproduct.Itsimplysays"if",appliedtoatotallyhypothetical,nonexistentstateofbeing.
