Opinião Pública publishes scientific articles on theory and methodology in public opinion, social and political behavior, political culture and democracy, media studies, elections, and political representation, articles which base their themes or hypotheses on theoretical frameworks and on empirical, quantitative, qualitative, or documentary research data in order to generate findings and support conclusions.

Opinião Pública is progressively aligning with open science procedures by adopting the CC-BY (Creative Commons Attribution) license, providing open access to data, analysis methods, and other research materials used in investigations, and allowing the submission of the author’s original version of a manuscript that has been previously posted on preprint servers: Scielo (, Social Science Research Network ( and ResearchGate (

Opinião Pública also accepts articles presented in conference proceedings. If approved, its publication is subject to the withdrawal of the Annals or Collection where it was previously published.

Decisions regarding the publication of articles belong to the journal's editors, by way of review by specialists. The evaluation may: a) recommend an article’s publication; b) recommend publication subject to the reviewers' suggestions; or c) reject its publication.

Positions and concepts emitted in signed articles are the sole responsibility of their authors and do not express the opinion of the Editorial Board.

There is no charge for article submission.

Opinião Pública supports the codes of conduct of Committee on Publication Ethics (COPE) (, as well as the guidelines of Conselho Nacional de Desenvolvimento Científico e Tecnológico ( and the manual for good practice in Science published by Fundação de Amparo à Pesquisa do Estado de São Paulo (

Opinião Pública publishes articles written in Portuguese, Spanish and English. Articles must be submitted (in .doc format) exclusively through Scielo / ScholarOne's online submission system: They cannot be subjected to any other vehicle at the same time.

Publication in the Opinião Pública is conditioned to the anonymous expert review process (double-blind review). In order to guarantee anonymity in the evaluation process, the name of the author(s) must NOT appear in the body of the text, as well as any other references that allow their identification.

Articles from the preprint server go through the one-blind review evaluation process.

If the article is approved for publication, the copyright must be assigned to Cesop/Unicamp, mentioning agreement with the publication, which must also include the name, full address, telephone, fax, e-mail, title and the institution to which author is linked. The author must also share databases, codes, methods and other materials used and resulting from the research presented in the published article.

Said abstracts should consist of no more than 900 characters, and an additional 5 keywords that identify the contents of the article.

If the paper is accepted for publication, these figures must be submitted in their original format so they can be edited.

The bibliography that is used must be presented at the end of the article, with authors listed in alphabetical order and in accordance to the ABNT norms (NBR 6023), as illustrated in the following examples.

We ask that attention be paid to the spelling of proper nouns and dates of publications cited in the text and in the references to minimize dubiety.

OPINIÃO PÚBLICA's staff will review typographical errors, orthography, grammar, spelling of proper nouns, acronyms, dates of publication in the bibliographical references in the body of the text and in references at the end of the article; however, the more careful authors are with all these aspects, the less likely it is that errors will appear in the published version.
