Brazil's 2026 Elections Show Shifts in Voter Abstention Amid Scientific Engagement with Candidates

The 2026 Brazilian elections have revealed nuanced voter engagement patterns with an overall rise in abstention alongside increased involvement from younger and older demographics. According to the Superior Electoral Court (TSE), the general abstention rate increased slightly from 20.79% in 2022 to 21.08% in 2026. However, participation improved significantly among voters aged 16 to 17, with abstention falling from 17.11% to 12.68%, and among those aged 70 and older, whose abstention dropped from 58.86% to 49.19%, despite remaining the highest across age groups.

In parallel to these electoral statistics, Brazil's scientific community has taken an active role in the political discourse. The Brazilian Academy of Sciences (ABC) and the Brazilian Society for the Advancement of Science (SBPC) jointly sent a comprehensive set of ten questions to all presidential candidates. This initiative engaged researchers nationwide, focusing on pressing issues such as sovereignty, democracy, inequalities, science and education, health, climate change, artificial intelligence, industry, energy, and the legacy for future generations. Full responses from candidates are publicly accessible, providing valuable insights into their visions for Brazil's future.

These developments underscore a dynamic electorate and a proactive scientific sector aiming to influence policy priorities. The evolving voter participation rates, especially among youth and seniors, contrast with a slight overall abstention increase, reflecting complex electoral engagement dynamics in Brazil. Meanwhile, the scientific inquiry into electoral platforms enhances voter information and highlights the critical interface between science and governance as Brazil charts its course forward electoral and policy-wise.
