Spain's CIS faces criticism over polling impartiality

The Centro de Investigaciones Sociológicas (CIS) in Spain is facing criticism regarding the impartiality of its sociological studies and public opinion polls. Critics argue that under the leadership of José Félix Tezanos, the institution has shifted from being a reliable scientific reference to a tool used to serve the partisan interests of the PSOE.

Some commentators suggest that the results provided by the CIS are increasingly suspicious and deviate significantly from other simultaneous studies. While supporters, including government spokesperson Pilar Alegría, have defended Tezanos by citing his accuracy in previous polls, detractors claim the methodology is being manipulated to align with the political objectives of the current administration.
