The Psychometric Society is “devoted to the development of Psychology as a quantitative rational science”. Engineering is often set in contradistinction with science; art is sometimes considered different from science. Why, then, juxtapose the words in the title:psychometric, engineering, and art? Because an important aspect of quantitative psychology is problem-solving, and engineering solves problems. And an essential aspect of a good solution is beauty—hence, art. In overview and with examples, this presentation describes activities that are quantitative psychology as engineering and art—that is, as design. Extended illustrations involve systems for scoring tests in realistic contexts. Allusions are made to other examples that extend the conception of quantitative psychology as engineering and art across a wider range of psychometric activities.
This article is based on the Presidential Address David Thissen gave at the 66th Annual Meeting of the Psychometric Society held in King of Prussia, Pennsylvania on June 24, 2001. The address was also given on July 16 at the 2001 International Meeting of the Psychometric Society held in Osaka, Japan.—Editor
