Nature AND Nurture: Enhancing group diversity in human sciences

Several human sciences stand at a crossroads, where the robustness of their findings is increasingly questioned due to the narrow demographics of their study samples, on top of others practice (e.g., statistics, transparency). Much of the published research indeed focuses solely on WEIRD (Western, Educated, Industrialized, Rich, and Democratic) populations and convenience samples, often recruited from university settings, without adequately addressing or cautioning about the generalizability of the results. This paper discusses the urgent need to expand the demographic range of research participants and outlines crucial steps and guidelines to include a wider array of human populations. Such efforts are essential to improve the generalizability and relevance of human sciences research worldwide.
