Beyond Bias to Western participants, authors, and editors in developmental science Running title: Beyond bias in developmental science

In this commentary, I argue that study participants, authors, and editorial members in developmental science are biased toward Western populations. First, I analyzed the study participants and first authors of articles in Infant and Child Development between 2006 and 2010 and between 2016 and 2020. The results suggested that most study participants and first authors were from the Western population. However, since 2010, the number of study participants and first authors from non-Western populations have gradually increased. Second, I analyzed editorial members from journals in developmental science. The results indicated that most editorial members were Western researchers. Given these analyses, I discuss what we can do to increase diversity in developmental science.
