A cross-cultural study of urban beauty shows that perceptions vary widely across individuals. Using Google Street View images and participant rankings from 20 countries, the research found no shared standards of beauty and no demographic explanations. While individuals were internally consistent, beauty judgments were deeply subjective, challenging data-driven approaches to urban design.

This study examines cognitive reserve theory by investigating the relationship between education and cognitive performance across developed and developing countries. Using numeracy and verbal fluency measures, it finds that higher education consistently improves cognition. However, cognitive performance is largely similar across countries once education level is considered, challenging assumptions about educational quality differences.
