Oh, I agree. Erikson does not appear to be a scientist at all. But I think the criticism should be along the lines of "he was not using the scientific method or citing sources which used such in the writing of this book", not personal attacks of "he doesn't have a degree in behavioral science".
To illustrate my point, this article[0] paints a very dim view of the science used in the book "Why We Sleep". The author of the book is a professor of neuroscience and psychology at UC Berkeley. Being in academia (even a professor at a prestigious school!) doesn't mean the book he wrote is de facto "scientific".
