Comments on an article by J. J. Arnett regarding the assertion that American psychology focuses too narrowly on Americans while neglecting the other 95% of the world's population. The authors agree with Arnett's call for greater attention to this issue. However, they fundamentally disagree with his position on issues related to generalizability and basic research. The goal of this comment is to provide a critical evaluation of Arnett's primary arguments as well as to offer alternative strategies for facilitating scientific progress on cultural and diversity issues.
