Still WEIRD, still underreported: An updated benchmark for psychological science.

= 1,217) and compared their samples with previous reviews. While the proportion of U.S.-based samples continues to decline, U.S. participants remain vastly overrepresented (59% of samples in 2024). For demographic representativeness, we found substantial improvements in demographic reporting since 2014, but participants' race, ethnicity, socioeconomic status, and education are still frequently omitted. For reporting standards, we evaluated compliance with Journal Article Reporting Standards for Race, Ethnicity, and Culture (APA, 2023). We find wide variation across journals in the adoption of practices, with some, such as including sample justifications, almost unanimously adopted, whereas others, such as conducting analyses of diversity, are much less common. Overall, our findings show that psychology still depends heavily on Western, educated, industrialized, rich, and democratic samples, with only modest and uneven progress toward inclusivity and transparency. By combining three evaluation criteria, we establish a holistic benchmark that can be used to systematically monitor change in these research practices in the future.
