NOTES The research we have used in this book looks at average differences between men and women, using samples of people in the United States. Although we included people from a variety of racial backgrounds in our research and interview samples, the average person in the United States is white, and we haven't (and by and large others have not) collected large enough samples within racial groups to say anything about how gender differences may vary across racial groups. As a result, there may be important differences that we aren't picking up. This research needs to be done (and in some cases is in the process of being done) and we hope that the issues raised in this book will inspire more of this type of work. Preface 1.
