4 ies of ntionl chrcter s their contribution to the wr effort. Their reports delt minly with the United Sttes, Jpn, nd Russi, but some of the lesser ntions were included s well. Drwing on trdition of culture nd personlity studies done in primitive societies, they sprked mssive upsurge of interest in the study of ntionl differences stted in psychologicl terms. In this first of series of surveys of reserch in the socil sciences to be conducted with UNESCO support, two Dutch socil scientists, Duijker nd Frijd, ssess wht hs been nd wht needs to be done in the study of ntionl chrcter. They review the confusing rry of currently used pproches nd conclude tht the most distinctive nd sound ttck requires tht we tret ntionl chrcter literlly s the pttern of personlity chrcteristics present in given popultion. Only thus cn we void confusing it with the people's history, their politics, or their institutions. This, of course, requires the use of psychologicl "tests" or mesures which re vlid cross-culturlly, nd our guides to the literture mke it cler tht there re not mny which cn qulify. It will be no gret surprise, therefore, tht Duijker nd Frijd report tht socil'psychologists hve not yet, for even one country let lone for ny set of ntions, systemticlly described the distribution of personlity chrcteristics in the popultion nd ssessed wherein the pttern is common or distinctive. The methods for such study re now more or less in hnd, however, nd we re convinced tht with fuller resources the importnt fctul questions fcing the field cn be nswered. We cnnot be eqully confident tht we will explin wht produces differences in the psychologicl composition of popultions-ssuming such differences exist-or wht consequences they hve in socil ction. There is vluble bibliogrphy of lmost 1000 items. The bibliogrphy, nd severl chpters which focus rther intently on detiled review of the literture, mke this essentilly specilist's book. Nevertheless, the presenttion is very well orgnized, nd the style commendbly simple nd lucid. The book will be red with interest by nyone willing to open his mind to the prospect of scientific study of ntionl differences.
