Theory Development (isr-theory-development)

When to trigger

• Your predictions are descriptive ("IT use relates to performance") with no mechanism
• You have an analytical model but the propositions are unmotivated or the comparative statics are not theorized
• A reviewer says "where is the IS theory?" or "this could be any social science"
• You must connect a behavioral and an economic/design logic (intradisciplinary work)

Two theorizing modes — match yours to your genre

ISR houses behavioral/empirical and analytical/economic & design-science research as co-equal genres. The shape of "theory" differs:

• Behavioral mode. Build an explicit causal mechanism centered on the IT artifact: how a feature of the system, platform, or algorithm changes cognition, affect, behavior, interaction, or organizing — then derive hypotheses a priori. State the boundary conditions and the level(s) (individual → group → firm → network → society). Theorize mediation (the process) and moderation (when it strengthens/weakens), not just main effects.
• Analytical mode. Specify agents, payoffs, information structure, and the IT-enabled decision (e.g., platform pricing, security investment, contracting, recommendation, data sharing). The assumptions are the theory: justify each, derive equilibrium results, and read the comparative statics as the propositions. The contribution is the qualitative insight ("when X, the platform optimally does Y"), not the algebra.

Make it sociotechnical and intradisciplinary

ISR's distinctive identity is bridging IS silos. The strongest manuscripts let the social and the technical co-determine the outcome and connect perspectives that usually stay separate — e.g., an economic model whose parameters are disciplined by behavioral evidence, or a behavioral study whose design is informed by a design-science artifact. Single-paradigm theory is publishable but the intradisciplinary, silo-bridging move is what ISR prizes. If you are combining methods, the 2025 multimethod-research framework editorial (ISR 36(2)) expects you to state how each method's theory informs the others.
