A1990report,forinstance,proposesthat"self-esteemisthelikeliestcandidatefora'socialvaccine',somethingthatempowersustoliveresponsiblyandthatkeepsusfromthelureofcrime,teenpregnancy,andeducationalfailure.Thelackofself-esteemiscentraltomorepersonalandsocialillsplaguingourstateandnationasweapproachtheendofthetwentiethcentury."

Despiteitscurrentpopularity,questionscanberaisedabouttheassumptionsunderlyingtheself-esteemmovement.Forexample,whatbenefitdoesathird-gradergainintellingherself,"Iamsmart,""Iamagoodstudent,"—allformsofthe"affirmativelanguage"advocatedbyDouglasBlochinhisbookPositiveSelf-talkforChildren?
