Theory and measurement in the public understanding of science: a rejoinder to Bauer and Schoon
In the paper `Mapping variety in public understanding of science' Bauer and Schoon apply a multi-dimensional coding to responses to the open question `Please tell me, in your own words, what does it mean to study something scientifically?', and draw some conclusions about cultural diversity from their results. I argue here that this study was inappropriate for two main reasons: first, because the open question was formulated and fielded not to elicit information which would reveal diversity but to assess public scientific literacy against a three-dimensional measure of understanding of three aspects of science which are relevant to the conduct and resolution of public science policy debates; and second, because the data set used by Bauer and Schoon was small and biased.
