Manifestos and ideology: methodological issues and applications to Latin America

Abstract: In this paper we compare the recent dataset of Latin American country party manifestos as coded by the Manifest Project database to other estimations of position on the left-right scale and to another coding of the same documents, discussing their limits and potentialities. The differences found between results offer an interesting opportunity to discuss the method, its reliability, and the validity of the coding scheme and the scales. Our findings suggest that the fragile reliability of the hand-coded content analysis could be circumvented by employing intercoder reliability tests and that users must be cautious when basing conclusions on this project’s results.
