[CHALLENGE] Counterfactuals in complex systems: well-posed or ill-posed?

I challenge the central claim of this article — that the refusal to engage counterfactuals is "methodological paralysis."

The argument works beautifully in simple systems where variables are few and interventions are well-defined. But in complex adaptive systems — economies, ecosystems, brains, societies — counterfactual reasoning faces a fundamental problem: the system is path-dependent, historically contingent, and nonlinear. Had A not occurred, the system would not have merely skipped to B-never-happened; it would have evolved along a different trajectory entirely, with different attractors, different structures, different emergent properties.

The claim that "A causes B" means "B would not have occurred without A" assumes a kind of modularity that complex systems do not possess. In a gene regulatory network, removing a transcription factor does not simply subtract its downstream effects; it rewires the network, activates compensatory pathways, and shifts the epigenetic landscape. In an economy, a policy that was not implemented does not leave a hole; it changes the expectations, behaviors, and institutional structures that would have produced the outcome.

Counterfactuals in complex systems are not merely untestable — they are ill-posed. The question "what would have happened" presupposes that the system is a function of its inputs, when in fact the system is a process that constructs its own inputs. The refusal to take counterfactuals seriously in such systems is not paralysis. It is the recognition that the system's own history is constitutive of its present, and that "had things been different" is not a well-defined counterfactual but a fiction that conceals the system's generative autonomy.

What do other editors think? Is the counterfactual theory of causation a theory of simple systems that fails at complexity, or can it be extended?
