               •   Although attempts at standardization would be premature, there
                   are advantages to working toward standardization and a common
                   metric while allowing metric diversity to continue.

                                      DISCUSSION

               Rebecca Maynard (University of Pennsylvania) said that the presenta-
            tions in this session collectively have done a good job of modeling what
            is often desirable, and sometimes not, about common metrics in the social
            sciences. They also illustrated for her the limitations of moving too quickly
            to common metrics. She then made a number of observations.
               She first observed that even when the science and technology for devel-
            oping common metrics exist, there is a time and place for common metrics.
            Cartwright and Bradburn (2010) laid out a three-step process of defining
            what is to be measured, selecting the metric for measuring it, and applying
            the metric. These same steps are also the gatekeepers demarking readiness
            for common metrics. The current poverty index came about because there
            was  a  readiness—a  need  in  the  war  on  poverty,  a  ready  metric,  and  an
            ability to apply that metric. There has been little progress to change this
            measure—despite very good work by NRC and other researchers demon-
            strating all the pitfalls of the current measures and other ways to measure
            poverty better—not only in large part because of inertia, but also because
            there has been no compelling reason to adopt an alternative.
               One  of  the  areas  in  which  Maynard  hopes  common  metrics  will  be
            developed is what she termed 21st-century skills, which are skills needed to
            improve the labor market readiness of those at the bottom of the skills dis-
            tribution and national productivity. Such vocational skills include aspects
            of self-regulation (or social competence), the ability to take direction, and
            reading. It seemed to her that the research literature may provide a strong
            foundation for understanding what to measure as well as the psychometric
            capacity to develop such a metric. Although none of the papers explicitly
            cautioned against creating common measures “before their time,” she be-
            lieves that the papers by Grusky and Hoyle came close.
               Maynard next observed that there is a temptation to clump concepts—
            the things to be measured—under neat labels and to want common mea-
            sures for them. In some cases, she surmised, consensus and utility might
            be much quicker to achieve for narrower concepts. In each of the three
            domains  considered  in  this  session—poverty,  social  mobility,  and  self-
            regulation—the concepts to be measured could well be context specific. She
            noted Michael’s point about why different definitions of poverty might be
            needed or different measures advantageous if the intent is to apply the mea-
            sure cross-nationally. The concept of poverty also might differ if the focus is
            on children, prime age adults, or the elderly. Similarly, she noted Grusky’s
