Why Science?
Edward Diener
Scientific research has been one of the great drivers of progress in human history, and the
dramatic changes we have seen during the past century are due primarily to scientific findings
—modern medicine, electronics, automobiles and jets, birth control, and a host of other
helpful inventions. Psychologists believe that scientific methods can be used in the behavioral
domain to understand and improve the world. Although psychology trails the biological and
physical sciences in terms of progress, we are optimistic based on discoveries to date that
scientific psychology will make many important discoveries that can benefit humanity. This
module outlines the characteristics of the science, and the promises it holds for understanding
behavior. The ethics that guide psychological research are briefly described. It concludes with
the reasons you should learn about scientific psychology.
