Dataset: Outsiders in Brazilian politics

We analyzed the social and political profile and political behavior in roll-call votes of deputies elected to the 56th Legislature of the Brazilian Chamber of Deputies (2019-2023). The deputies were divided into three groups: The established (those who were not in their first term); the outsiders (those who were in their first term); and the Renovators (outsiders who were members of supra-party political renewal organizations). The objective was to verify significant differences existed among the groups and whether the Renovators exhibited peculiarities in their parliamentary behavior. The results showed that the groups presented differences in terms of age, race, party ideology, and campaign finance patterns. However, through analysis of mean differences, the article concludes that there is no difference among the average party loyalty indices of the parliamentarians in each group, indicating very similar behavior among the deputies. This finding undermines the alleged novelty brought by the wave of political renewal in 2018 in Brazil.

本研究分析了2019-2023年当选巴西众议院第56届议会的议员的社会与政治画像，以及其在唱名投票中的政治行为。研究将议员划分为三类：资深议员（非首次任职者）、新人议员（首次任职者），以及革新派议员（Renovators，即作为超党派政治革新组织成员的新人议员）。本研究旨在验证各组之间是否存在显著差异，以及革新派议员在议会行为中是否表现出独特性。研究结果显示，各组议员在年龄、种族、政党意识形态以及竞选资金模式方面均存在显著差异。然而，通过均值差异分析，本文得出结论：各组议员的平均政党忠诚度指数并无显著差异，表明全体议员的议会行为高度相似。这一发现削弱了外界所称的2018年巴西政治革新浪潮所带来的创新性。
