Criticism mounts against CIS President José Félix Tezanos

José Félix Tezanos, president of the Centro de Investigaciones Sociológicas (CIS), is facing intense criticism from political opponents and professional polling firms following recent electoral surveys. Critics argue that the CIS data, which is funded by public money, appears to favor the main party of the governing coalition by showing significantly higher support for the PSOE compared to other demographic studies.

Opponents have characterized the surveys as instruments of electoral propaganda rather than scientific tools, alleging a pattern of inflating socialist voting prospects. The controversy has led to professional discredit and sharp 'ad hominem' attacks within the political landscape, with some analysts questioning the technical integrity and impartiality of the institute's methods.
