Responds to the comments of LoSchiavo F. M. and Shatz M. A.; Webster G. D., Nichols A. L., and Schember T. O.; Stroebe W. and Nijstad B.; and Haeffel et al. on the author's original article regarding the assertion that American psychology focuses too narrowly on Americans while neglecting the other 95% of the world's population. The author indicates that the four comments were well chosen in that they represent quite different reactions to his article. In this rejoinder the author addresses the issues raised in each of the comments, first the two supporting comments and then the two opposing comments. Following this, he addresses the more general problem that cuts across the comments: American psychology's dominant philosophy of science. (Contains 1 footnote.)
