For analyses involving the five discrete categories
in Figure 1, we used the following computations:
Reporters were articles that received a rating
of 1 or 2 on theory building and a 1 or 2 on theory
testing. Testers were articles that received a 1 or 2
on theory building and a 4 or 5 on theory testing.
Articles that received from 2.5 to 3.5 on theory
building and from 2.5 to 3.5 on theory testing were
categorized as qualifiers. Articles that received a 4
or 5 on theory building and a 1 or 2 on theory
testing were categorized as builders. Finally, expanders
were articles that received a 4 or 5 on
theory building and a 4 or 5 on theory testing
