Research index entry, released 31 October 2026 (v1.2). Independent reproducibility audit of 79,500 political images from Haim and Jungblut’s European election study. We reproduced all 28 published country percentages and the source regression models, and identified a numerator–denominator mismatch in the descriptive country table. We also found that image metadata dimensions and recorded face coordinates do not consistently refer to the same pixel frame. The close-up analyses are sensitive to coordinate assumptions; no unique corrected rate is claimed.
