(p.viii) But that which Galen noteth more particularly, touching this, is, that Philosophie
and Phisicke, are the most uncertaine of all those wherewith men are to deale. And if this
be true, what shall we say touching the Philosophie whereof we now intreat, where with
the understanding, we make an anatomie of a matter so obscure and difficult, as are the
powers and faculties of the reasonable soule? In which point are offered so many doubts
and arguments, that there remains no cleare doctrine upon which we may relie.

The theme of this book is the search for the origins of human intelligence differences in
terms of brain functioning. Each topic within the field is covered in an essay-type style.
That is permissible because the writer makes reference to the principal empirical reviews
of each field, and wrote some of them. Giving the reader the undigested mass of facts is
like a layperson being handed raw scores from the Wechsler Adult Intelligence Scale, or
the NEO-Personality Inventory-Revised; it's the interpretation of the disinterested
expert that one is paying for, not the raw materials, just as you want a builder to
construct a house and not dump the materials in piles on the site and leave you to
assemble them. In other areas of scientific endeavour, especially medical science, the be-
all and end-all of the topic is the meta-analysis; impressionistic judgement calls are
derogated. But many important decisions in our field demand such judgement calls. The
proximity between a test and a theoretical construct, whether or not an association is
large enough to be ‘interesting’, whether a line of investigation is worthwhile at all, what a
correlation between two samples of human behaviour (psychometric test score versus
putative information processing component) means; all these and more are the decisions
we make in our daily work.
The main discoveries and insights, historical and contemporary, are covered. The

principal concern, however, is to show how an area of research has gone about its
business. So there is a particular interest in historical precedents of current research
fields. There is an emphasis on the way constructs are considered and how associations
are viewed. There is a focus on the place of theory and with the balance between
available evidence and allowable speculation. To be frank, there is a strong dislike of
theory such as it is manifest in the field, and a lot of the book is an appeal to go with the
data and to be quick to give up on so-called theory which, in psychology, is rarely the
well-aimed headlight that, at best, it can be in the physical sciences.
I wrote the book about the origins of psychometric intelligence differences because I
know about this area, but the book could have dealt with many topics in psychology that
are used for prediction and are also mysterious with regard to the origins of their
differences. Personality, some aspects of memory, attention, all might have been topics
about which a book with a similar structure and comparable concerns could have been
written. So don't be too smug when it is shown how little researchers in intelligence know
of the history of their topic, how poor are some of their data sets, how unsupportable are
some of their conclusions, and how little they have advanced in terms of process
understandings since the early 1900s. This is a book whose form and general points are
meant for the psychological everyman, and the criticisms apply beyond human intelligence
research.
(p.x) Some paragraphs ago I mentioned that the reader was paying for the voice of a
disinterested expert commentator. Disinterested voices are not legion in the field of
intelligence differences. And the reader must be warned that, since the rebirth of the
topic of information processing from the 1970s to date, there have been writers of books
and articles who view some facets of this area of research as near moribund and/or
fruitless (e.g. Ceci 1990; Lohman 1994) and some who see mostly promise (Matarazzo
1992; Brand 1996; Jensen 1998a). In addition, there are those who may be
characterized as honest brokers, people not hugely active empirically within the field but
who have reviewed the evidence and passed even-handed judgement. In this category
sit, for example, Brody (1992) and Mackintosh (1998), although Brody's spectacles have a
just-noticeable rose-sanguine tint and Mackintosh moves between choleric-yellow and
melancholic-blue lenses. With regard to this writer, there is a noticeable change from the
tiro medical undergraduate infected with Chris Brand's conquering enthusiasm (Brand
and Deary 1982). Scales have fallen from the eyes; procedures, samples, analyses,
constructs, theories, all have generated cause for complaint.
In the course of composing this series of related essays I abused the good nature of
many valued colleagues. Elizabeth Austin, Peter Caryl, Fergus Craik, Ted Nettelbeck,
Aljoscha Neubauer, Robert Plomin, and Lawrence Whalley provided valuable comments
on earlier drafts of chapters. My University of Edinburgh colleagues Peter Caryl and
Alasdair MacLullich contributed equal shares to the writing of Chapter 9. Janice
Sutherland translated Wolff's Latin in Chapter 2. Alan Bedford read through the entire
proof. Roy Welensky drew the figures. The conclusions and opinions hereinafter are mine.
