Goodresearchisdrivenbyimpatiencewithbadanswerstointerestingquestions.But

Intheparlanceofsocialmedia,scientificdiscoverybeginswitha“WTF”moment.

Scientificdiscoverybeginswhenascholarobservessomethingcontrarytoexpectationsand

Butnotjustanysurprisewilldo.Anyonewhohaseverparentedayoungchildisfamiliar

withthequestions,bornoutofwonder,suchasthosethatourchildrenaskedmypartnerand

me:“whyistheskyblue?,”“wheredoesthesungo(attheendoftheday),”?or,“ifmybrain

Question1:WhatdoIwishtoexplain?(TheIntroduction)

FollowingKuhn’sdescriptionofscientificrevolutions,mostgoodworkbeginswitha

puzzlingobservation.Beginningwithobservationisimportantbecausegoodreaderswouldlike

tobeconvincedthatthephenomenonyouareexplainingactuallyoccurs(thoughitis

frequentlyfruitfultoengageinthoughtexperimentsaboutthingsthathavenotoccurred).

Thisstepisbynomeanstrivialandconsiderablemethodologicalsophisticationmaybe

youwishtoexplain.

SamuelHuntington’sclassicPoliticalOrderinChangingSocieties(1968)seekstoexplain

therisingpoliticalinstabilityheobservedaroundtheworld.Asevidenceofthisrising

varioustypesrosealmostmonotonicallyfrom34in1958to57in1965(Table1.1).Thisisa

dramaticincrease:inlessthanadecadethenumberofconflictsnearlydoubled!Theproblem,

however,isthat,asaresultofdecolonization,thenumberofindependentcountriesinthe

worldalsogrewrapidlyduringthisperiod.IfonetakesHuntington’snumbersanddividesthem

bythenumberofindependentcountriesineachyear(asameasureoftheopportunityfor

militaryconflict),therelativefrequencyofmilitaryconflictactuallydeclinedoverthisperiod.

Sincemilitaryconflictwasjustoneproxyforpoliticalinstability,itisentirelypossiblethat

therelativefrequencyofconflictisabetterindicatorofpoliticalinstabilitythantheraw

frequency,youwouldbejustifiedinwonderingifthephenomenonexplainedinthesubsequent

fourhundredorsopagesactuallyoccurred.

isoftenbestaccomplishedwiththepresentationofclearlypresented,wellthoughtout,

descriptiveevidence.Whilethisoftenrequiresafairamountofmethodologicalskill,

sometimesitsimplyrequiresnumeracy–which,unfortunately,isofteninshortsupply.

Question2:Whydoesitneedtobetoexplained?(TheLiteratureReview)

Havingexplainedthatthisthinghasoccurred,itisimportantforauthorstodemonstrate

thata)thisthingviolatesexpectationsinsomeway(i.e.“somethinghasgonewrong”)andb)

thatthisviolationmay“proveconsequential.”Inotherwords,inthewordsofMilesDavis,“so

what?”

varies.BeinglesssupportivethanIshouldhavebeen,Iasked,“doyouhaveatheorythatleads

ustoexpectthisvariabletobeaconstant?”Variablesvary.Itisevenintheirname.

Observingthatvariation,therefore,hardlyconstitutesasurprise.Soifvariationinavariable

doesnotconstituteaviolationofexpectations,whatdoes?

Asacomparativepoliticsscholar,itpainsmetosaythatIhaveattendedmanyseminar

talksoverthelastfewdecades,mostgivenbysuccessfulandinfluentialseniorscholars,where

theworkinprogressismotivatedbyanassertionthatissomevariantofthefollowing“puzzle”:

theoryQclaimsthathighlevelsofvariableXshouldcauseYtohappen,butincountryiattimet,Xwasveryhigh,andYdidnotoccur.

Theproblemwiththis“puzzle”isthatoncethemisunderstandingitisbasedonisclearedup,it

isnolongerapuzzle.Themisunderstandingisthis:withveryfewexceptions(Icannotthinkof

ofclassificationerror(didYoccurordiditnot?wasXreallyhighorlow?andcomparedto

what?)itisbesttothinkofourhypothesesasprobabilistic.WhichmeansthemosttheoryQ

canclaimisthat“highlevelsofvariableXshouldmakeYmorelikelytohappen.”

Consequently,thefactthatYdidnotoccurincountryiattimet,despitethefactthatXwas

veryhighisnot,atleasttomyear,particularlypuzzling.Unlikelyeventsareexpectedtohappen

occasionally.Consequently,onecannotreasonablycallaprobabilisticconjectureintoquestion

Question3:Whatistheexplanation?(Theory)

Agoodexplanationwilltakeanobservationthatissufficientlysurprisingthatitjustifies

yourstudy,andturnitintosomethingthat,inretrospect,shouldhavebeenexpectedallalong.

InwhatremainsoneofthefewbooksIknowofthatattemptstoteachpeoplehowtoexplain

things,theauthorsofAnIntroductiontoModelsintheSocialSciences(LaveandMarch,1975)

describeexplanationasaprocessinwhichoneimaginesapriorworldsuchthat,ifitexisted,

thesurprisingfact(s)wouldhavebeenexpected.Technically,anysetofstatementsthat

logicallyimplytheoccurrenceoftheanomalousobservationconstituteanexplanation.But

goodexplanationshaveadditionalattributes,andwewouldliketoproducethebest

explanation.Asatisfyingexplanationwillgivethereaderanunderstandingoftheprocessor

mechanismthatislikelytoproducethepreviouslyanomalousobservation.Readerswantto

knowhowsurprisingeventscameabout,andexplanationsshouldtellthem.Good

explanationsareefficient–theratioofthingstheyexplain(implications)tothingstheyrequire

youtobelieve(assumptions)ishigh.

18

Thereisanoptimaldegreeofnoveltytoanexplanation.Anexplanationshouldbe

interesting,yetsound.By“interesting”Imeanthatanexplanationshouldcauseustoseethe

worldinanewway.By“sound”Imeananexplanationshouldfitinwithotherthingsweknow

abouttheworld.Anexplanationthatcausesustoseeeverythinginanewwayislikelytobe

wrong.Anexplanationthatdoesnotrequireustochangeourmindatallisprobablyjusta

corollaryofthingswealreadyknew(and,byextension,ourmotivatingpuzzlemustnothave

beenmuchofapuzzle).

Finally,explanationsmustbelogicallyconsistent.Ihavehadempiricallyminded

politicalscientistsandinternationalrelationsscholarstellmethatformaltheoryisnot

importantbecausetheyaresophisticatedenoughtolivewiththeoriesthatcontain

contradictions.Thisisnonsense.Itcanbeshownwithelementarylogicthatanythingfollowsa

contradiction.Consequently,ifyourtheorycontainsacontradiction,anythingcanbesaidto

followfromit.Asaresult,acontradictorytheoryrulesnothingoutand,therefore,noamount

ofempiricalinformationwillbesufficienttofalsifyit.Sincepotentialfalsificationisthe

hallmarkofscience,atheorythatcontainsacontradiction,therefore,isnotascientific

theory.12

Onewaytoincreasethelikelihoodthatyourexplanationislogicallyconsistentistotry

tocaptureitwithaformalmodel.Formalmodelsallowustodemonstratethatour

makingtheassumptionsofourexplanationexplicitwearemorelikelytonoticeifthey

Whilethesebenefitsofformalizationareundeniable,itdoesnotfollowthatevery

explanationshouldbeformalized.Itypicallyencouragemystudentstofirstarticulatetheir

explanationsasastorythatrevealsaprocessthatproducesthepreviouslyunexpected

observation.Formalizationisonlynecessarywhenonehearssuchastoryandasks,“whywould

peopledothat?”or,equivalently,“Thatdoesn’tsoundlikeanequilibrium,”or,“isn’ttherea

withsuchquestions,agoodformalmodelcanoftenprovideanswers.Thus,Itellmystudentsto

Practicesthatencouragegoodquestionasking

“theskill,wit,andgenius”capableofrecognizingwhenthingshave“gonewronginwaysthat

mayproveconsequential.”OfKuhn’sthreedesiderata,“skill”seemstheleastconstrainedby

naturalabilityand,therefore,mostresponsivetotheenvironmentswecreate.Whileartistic

Butwhilemethodstrainingisextremelyhelpful,itisnotsufficienttoproducescholars

Themissingpieceinmostofourgraduateeducationiswhatmusicianscall“etudes.”

thenamecanbedevelopedafteradozenorsoattempts.

Consequently,Ihavearguedthatproblemsetsin“substantiveclasses”canhelp

studentsbecomeproficientataskingandansweringthequestionsthatwillmakeforinnovative

research.Ananalogytothevisualartsmightbeuseful.Whenstudentsarelearningtodraw,

theyarenothandedablanksheetofpaperandtoldto“thinkofsomethinginterestingtodraw,

area.“ExplainwhyXoccursunderZcircumstances.”“IfPexplainsY,whatelseoughtwe

observe?”“WhyisQaninterestingquestion?”“DoesFigure2countasconfirmingor

disconfirmingevidenceforhypothesis2,andwhy?”

Studentsneedalotofexperience“makingmusic”beforethey“havesomethingtosay.”

Iftheanalogytotheartsdoesnotresonatewithyou,considerthefollowing.Politicalscience

andinternationalrelationscantakealessonfromtheso-called“benchsciences”where

studentsworkonmanyprojectsasmembersoflargeteamsbeforetheyaretaskedwiththe

33

responsibilityofdecidingonthetopicofthegroup’snextproject.Experienceandrepetition

helpsstudentslearnwhatworksandwhatdoesnot.

Whilegraduatepedagogyisimportantforstimulatingcreativequestionaskingand
