Networks, Ecosystems, and Trust in Measurement

September 13, 2020

Before the metrology of intangible assets can get off the ground, before we will be able to buy calibrated instruments for measuring abilities, attitudes, performances, and outcomes off the shelf like we do clocks, thermometers, and bathroom scales, we will need to develop trust in the dependability of our measures by building out persistent and reliable social network connections across different sectors (Alder, 2002; Andrade-Garcia, et al., 2020; Ashworth, 2004; Latour, 1987, 2005; O’Connell, 1993; Porter, 1995). Demand for the tools and unit standards will emerge and grow as awareness of the value obtained spreads, and as habitual usage leads to confidence in the processes and outcomes. As demand, awareness, and habits like these arise, researchers and practitioners will focus less on isolated and centralized data analyses, and more on collaborating in the creation and maintenance of shared quantity values (Fisher, et al., 1995; Fisher, 1997, 1998, 1999; Fisher & Stenner, 2016; Smith & Taylor, 2004; Stenner & Burdick, 1997; Stenner, et al., 2013, 2016; Stone, 2002; Stone & Stenner, 2018). Far from being a merely technical task, a number of social, emotional, aesthetic, ethical, political, economic, and other factors complicate matters considerably.

But to start from a plausible beginning, a better term than “networks” is what Latour (2005, p. 143) calls “worknets.” In the Rasch world, we can see these as ecosystems functioning at individual (kidmap), instrumentation and unit standard (Wright map), and predictive theory (construct map) levels of semiotic levels of concrete, abstract, and formal complexity (Fisher, 2018b, 2020; Fisher & Stenner, 2018a; Fisher & Wilson, 2015).

Different communities tend to focus their interests on just one of the different levels. though they implicitly make use of the others. In the natural sciences, the experimentalist, instrument-maker, and theoretician communities are more disconnected and disunified than one might expect, but in a complex way that makes them more effective and coherent than they could be if they were homogenously interconnected (Galison, 1997, pp. 46, 785-799, 843-844; 1999; Galison & Stump, 1996; Woolly & Fuchs, 2011).

Though these communities see and value the objects of their interests differently, they find enough common ground to coordinate and align their activities. The position of the objects of interest on the borders between the various scientific communities and others (accountants, lawyers, bankers, shareholders, customers, managers, etc.), as well, leads to them being referred to as boundary objects (Star & Griesemer, 1989, p. 392; also see Star, 2010; Star & Ruhleder, 1996; Bowker, 2015; Bowker, et al., 2014, 2015):

“Boundary objects are objects which are both plastic enough to adapt to local needs and the constraints of several parties employing them, yet robust enough to maintain a common identity across sites. They are weakly structured in common use, and become strongly structured in individual site use. These objects may be abstract or concrete. They have different meanings in different social worlds but their structure is common enough to more than one world to make them recognizable, a means of translation. The creation and management of boundary objects is a key process in developing and maintaining coherence across intersecting social worlds.”

We can expect the same kind of disunity across communities in education, health care, management, etc. Indeed, we are already quite familiar with it, given the theme of this thread concerned with whether it is realistic to try to train teachers as functional Rasch measurement experts. But in addition to this experience, we also have the array of tools we need to meet each community where they are:

  • Practitioners like teachers, clinicians, and managers want kidmaps (Wright, et al., 1980; Wilson, 2004; Chien, et al., 2018) or their group-level equivalents, which provide the contextualized concrete data and formative guidance they need to know what to do next, to review the developmental, healing, or improvement trajectory, and to keep the goal in mind.
  • Researchers and analysts focus on abstract standards of representation, and so want Wright maps (Wright & Masters, 1982; Wilson, 2011) and the technical demands of instrument and experimental designs, statistical comparisons, and invariance assessments.
  • Theoreticians focus on formal conceptual structures, and so want explanatory models and construct maps (Stone, et al., 1999; Wilson, 2005) capable of demonstrating that the variable measured is the intended one, demonstrated by being able to write items to specifications and obtain the expected calibrations.

Putting all of this together effectively extends the thing-word-concept semiotic triangle of natural language into the data-instrument-theory semiotic triangle of science (Fisher, 2018b). This extension into contexts explicitly conceived and designed as multilevel ecosystems is well underway (Morrison & Fisher, 2018, 2019, 2020).  This extension sets the stage for creating a new demand for communicable results reporting, where research papers and practical applications within a domain are meaningful, interpretable, and transferable for individuals over time, across individuals and instruments (collections of items), ways they currently are not.

This all undoubtedly sounds unrealistic to the point of impossible. The same was true of every advance in science. If matters were merely technical, analytic, and logical, the unrealistic demands to be made would truly put goals like these out of reach. In extending the semiotic triangle in new ways, however, this proposal has solid grounding in past successes, a grounding that includes thorough integration with the affective and bodily experiences of communication (Abram, 1996; Boedker & Chua, 2013), metaphoric process (Fisher, 1994, 2011, 2012), aesthetics (Fisher, 2018a, 2020; Fisher & Stenner, 2018b), ethics (Fisher, 2016), interpretation theory (Fisher, 2003a/b, 2004), econometrics (Fisher, 2010, 2019b), and the politics balancing powers across executive, legislative, and judicial branches of government (Fisher, 2009, 2019a; Nielsen, et al., 2007). We will also need to expand the number of levels of complexity we include in our models and results (Morrison & Fisher, 2020, slides 67-75; Scribner, et al., 2000), but that’s another story for another time.
