I do not pretend to have any kind of expertise in cross-cultural studies, but I thought that this book was a good way to be introduced to some of the elementary issues of the subject. The book seemed to be concise and yet contain a great deal of information. Rather than simply presenting all of the information in a lecture format, a lot of it was transmitted inductively through reading and participating in various exercises. I purchased the book in an electronic format which made interacting with the workbook aspects of the text frustrating but nonetheless helpful. Knowing myself, I would have probably had the same difficulty if I had a hard-copy of the book (I'm hesitant to mark tests in books for fear that I will want to take them again objectively later).
I did, however, find it frustrating that because each chapter contained the same kinds of exercises he used the exact same wording for the instructions and precautions for each of them throughout the book. This made it difficult to remain focused enough to re-read those paragraphs again a third and fourth time. Perhaps his goal is to reinforce the dangers of stereotyping but this may have been accomplished at the expense of sounding extremely redundant.
Overall, I appreciated the intent of the book and think he accomplished his goal of getting his audience to examine their own cultural assumptions and become aware of differing cultural assumptions. Throughout the book I found myself thinking, Wow, I would never have interpreted that behavior in that way. An eye-opening and practical introduction to interacting with those people who do not come from the same culture or who have different cultural values as you do.
