You have the opportunity to deepen your investigation into psychological length. You can also recast your experiment and try again to recover physical measures. Rather, measures and quantitative relationships are artifacts of technology and require persons trained in reading, creating, and maintaining that technology to have any impact. Rather, measures generalize around the globe only to the extent that laboratory work is condensed into a portable technology that reproduces laboratory conditions anywhere. A single researcher might well manage to simultaneously invent and discover a new and generalizable variable, but his or her metric will become the standard only to the extent that it is reproduced by others and agreed upon by them for use.
Universal metrics are as much social phenomena as natural.
With conjoint measurement models, the psychosocial sciences are, for the first time, obtaining some convergence of independent experiments. The next step in the struggle for generalizable scientific quantification is the formation of the crucial metrological networks through which reference-standard instruments and samples are circulated, and so used to maintain the uniform metric standard. It is at this point that Rasch measures will become truly scientific. The design of experiments. The creation of universality by the circulation of particulars.
