Candidate Smiles Significantly Affect Electoral Outcomes

A recent study analyzing 9,000 French local election manifestos (2022 and 2024) and a 1,000-person online experiment used AI to detect candidate smiles and measure voter responses. It finds non-smiling female candidates lose roughly two to three percentage points relative to non-smiling men, while smiling adds value for men. The results indicate asymmetric gendered penalties with implications for campaign imagery strategies.
