A post-election analysis of Costa Rican runoff polls reveals significant variations in accuracy. The CNC polling firm demonstrated the highest precision in predicting the final results of the presidential runoff election. Guarumo and Ponderador polls trailed in accuracy, while Atlas, previously the most accurate in the first round, proved least accurate in the second. This assessment, published by La Silla Vacía, examines the performance of different polling methodologies. The findings highlight the challenges of accurately gauging voter sentiment during a two-candidate race. The analysis provides insight into the strengths and weaknesses of each firm’s approach to predicting election outcomes.
