A Lost Decade? Laszlo Radvanyi and the Origins of Public Opinion Research in Mexico, 1941-1952

This article documents public opinion research activities inMexico in the 1940s and the role played by Hungarian professorLászló Radványi, who immigrated to thatcountry at the height of World War II. Our research relies onseveral of Radványi's publications archived in differentcountries, as well as on interviews with family, acquaintances,and experts on the work of his wife, the German poet Anna Seghers.During his years in Mexico, Radványi founded the ScientificInstitute of Mexican Public Opinion, in 1941, and the InternationalJournal of Opinion and Attitude Research, in 1947—a forefatherof today's IJPOR. He was also a founding member of WAPOR. Hisearly "sample surveys" raised important methodological issuesand recorded opinion results that reflect the vibrant timesof war and policy making in a modernizing country. However,Radványi's contribution to the profession has been virtuallyforgotten. Until now, accounts about how public opinion researchbegan in Mexico either ignored Radványi's works or reducedhis ten years of survey research to a single footnote. Thisarticle is an attempt to fill this enormous omission and highlightsome of Radványi's contributions to these early stagesof survey research.

“公意”与“舆论”之间:五四时期李普曼《舆论》的知识传播和话语实践

基于新发现的袁昌英《公意之源》,并与陶孟和的书评比较,考察李普曼《舆论》作为一种现代性话语在中国的传播与实践的问题。《舆论》推动了近代西方"public opinion"从哲学论述转向现代性的知识和概念,但其核心概念仍融合了"公共意志"与"公众意见"两方面涵义,作为现代性话语尚具有两歧性。这个特征为五四时期的中国学者提供了"舆论"与"公意"的两条阐释路径。陶孟和用书评形式引介《舆论》,关注其在政治心理学上的创新意义;袁昌英则以近似于政论文的形式,评述李普曼的新舆论观、大众媒介观和政治传播观,实已触及现代传播学的范畴。陶、袁都被李普曼的民主理论修正观点所吸引,对于著名的"李普曼-杜威之辩",也有精英主义与大众主义不同的评论视角。从话语实践上看,《舆论》参与了一战以后中国知识界对西方民主制度的反省思潮。

‘Here is a book that makes you want to shout, "Finally!"’That is the opening sentence of a recent book review that theauthor of this review wrote for the International Journal ofPublic Opinion Research about Campaigning for Hearts and Minds:How Emotional Appeals in Political Ads Work by Ted Brader (2006).The remark refers to the fact that Brader’s book focuseson an issue that has thus far received very little attentionin the field of communication studies, or, for that matter,in the fields of political science or sociology, namely, themajor role emotions play in explaining collective behavior,social decisions, opinion formation and—especially inthe case at hand—the effects of media coverage on opinionformation.
