The book first fleshes out a handful of immigration myths that some people purportedly hold only to debunk them by appealing to the authors' and their colleagues' academic research. One myth is that immigrants today are slow to assimilate. Another myth is that immigrants impoverish the communities that they join. The book's ambition is to engage with the political debates of the day; those interested in science, can read the papers. This ambition comes at the price of necessarily dating the book.
The book could have been shorter. It prides itself on not needing to rely on anecdotes in order to uncover general tendencies, and yet indulges in anecdotes galore. The book sets out not to weigh in on policy matters, and yet does not miss the opportunity to nudge the reader to accept open borders. At the same time, the book's provocative policy proposals also make the book memorable, raise bigger questions beyond the book's scope, and set the book apart from the presumably dry academic prose on which it is based.
