Study Examines Polarization and Fact‑Checking Impact in Brazil’s 2022 Election

A new study published in Nature investigates Brazil’s 2022 election environment. Researchers track the dynamics of sociopolitical polarization among voters. The analysis focuses on how misinformation spread during the campaign. It also evaluates the effectiveness of information designed to correct misperceptions.
