The attempt to understand and improve methods, and to do so via theorizing
them, is at the center of an intelligently evolving cognition.
— Clifford Hooker (1987, 291)
Above all, if a raised standard of education in methods is to be achieved, it is
necessary to engender, beyond any knowledge of particular skills and formulae
as such, a perspective as to what methods are most appropriate to various areas
and occasions.
— Raymond Cattell (1966, 5)

Preface
Although modern science is made up of many parts, scientific method is
its centerpiece. The centrality of method to science stems from the fact
that it provides scientists with the primary form of guidance in their quest
to obtain knowledge about the world. As fallible inquirers, scientists face
immense challenges in their efforts to learn about the complexities of
nature. In good part, these challenges are met through the use of methods,
which provide scientists with the cognitive assistance that they need to
undertake successful inquiry.
However, despite its undoubted importance, scientific method receives
less considered attention than it deserves, from both scientists and educa-
tors. Of course, scientists take method seriously, but I believe that they
do not take it seriously enough. Scientists themselves, including psycholo-
gists, learn about research methods and how to use them to conduct their
research. However, the nature of this learning, and of the instruction they
receive about how to employ these methods, is better described as a mix
of training and indoctrination than as a genuine education designed to
provide a critical, in-depth understandi ng of the methods. Although
professional science educators sometimes promote the importance of the
epistemological foundations of scientific method, the influence of this
source of learning on the regular teaching of research methods is minimal.
Psychology, which provides extensively in its curriculum for teaching
research methods, uses textbooks that make little or no effort to inform
students in depth about the nature of scientific method. Nor does its
curriculum foster a critical appreciation of the various research methods
that its textbooks deal with. Consequently both psychological scientists
and psychology students tend to have a limited understanding of scien-
tific method, which in turn contributes to a misuse of research methods
and a suboptimal level of scientific literacy.
Description:This book considers scientific method in the behavioral sciences, with particular reference to psychology. Psychologists learn about research methods and use them to conduct their research, but their training teaches them little about the nature of scientific method itself. In Investigating the Psyc
