However, before purchasing How Genes Influence Behavior and jumping headlong into its discussion of behavioral genetics, it is perhaps beneficial to take heed of some words the authors share in their introduction. They explain, "We're not relating a story, so you can, if you like, read at random (relatively speaking at least)" (p. 4), and unfortunately there were times where we felt ready to embrace this advice. The book's organization sometimes feels counterintuitive (though certainly not random) because rather than keeping similar kinds of chapters together or presenting the methods listed in the appendix sequentially, the text seems instead to roam about. For example, the book begins with an in-depth look at schizophrenia, moves into the next chapter to discuss linkage analyses, and then just as readers might be settling into a consideration of the methods associated with human studies, it returns to a discussion of human phenotypes, only to yank readers back again to a discussion of the various kinds of association analyses in the subsequent chapters. Moreover, an entire chapter is spent on schizophrenia, whereas other kinds of human behavior only receive a few pages of explicit attention (e.g., alcoholism, depression, personality disorders), and some kinds of human behavior are only mentioned in passing (e.g., childhood disorders such as autism). In their defense, though, schizophrenia is perhaps the most interesting psychiatric illness to the casual reader, and it does make for an interesting gateway to discussing twin and family studies.
