CHAPTER 1<br />

is a key term from psychological measurement: “A construct is<br />

some postulated attribute of people, assumed to be reflected<br />

in test performance” (Cronbach & Meehl, 1955, p. 283). The<br />

point is that the construct is “postulated” or hypothetical—as<br />

opposed to a quality that we can directly observe, such as a person’s<br />

height. As we shall see, there are many tests that purport<br />

to measure EI, but research is needed to show that whatever<br />

quality is measured by a test can be described as “EI.”<br />

Indeed, the second pillar is developing a theory of EI that<br />

explains the source of variation in test scores, and its consequences<br />

for behavior. Theory building and justification is perhaps<br />

the most essential characteristic of the scientific enterprise<br />

(Kerlinger, 1973). In short, what shapes a person’s EI, and what<br />

difference does it make? This process is known as construct validation.<br />

It goes beyond simply showing that test scores predict<br />

the person’s behavior in building an understanding of the nature<br />

of the psychological processes and structures that underpin our<br />

measurements of EI. For example, in conventional intelligence<br />

research we can investigate genetic and environmental influences<br />

on development of the brain areas that support reasoning<br />

and abstract thinking. We can also look at how the individual’s<br />

level of intelligence influences their educational attainments,<br />

career success, and even health (e.g., Deary, 2000). Theory<br />

building in psychology is never finished. Successful research<br />

programs lead to the progressive theory refinement and modification,<br />

which in turn generates new directions for research.<br />

With sound tests, and an understanding of what test scores<br />

actually mean, we can build a third pillar of our science, the<br />

application of research on EI to address real-life issues. It is<br />

plausible that wise men and women have been using their EI<br />

for good since the origins of the human species. The hope is<br />

that a scientific understanding of EI will allow a more systematic<br />

use of these competencies. Perhaps mediocre teachers,<br />

therapists, and managers may be trained in the skills that their<br />

emotionally gifted peers have developed spontaneously. A scientific<br />

approach is essential on several grounds—identifying<br />
