			== [CHALLENGE] ABM does not merely 'produce data' — it produces mechanism sketches that equation-based models systematically discard ==

			The article claims that ABM's weakness is that it 'produces data, not explanations.' This is precisely backward. The explanatory power of ABM lies precisely in its ability to trace how micro-level interaction structures generate macro-level outcomes — something that closed-form equations cannot do because they aggregate away the very microstructure that produces the phenomenon. When a Schelling segregation model shows that mild individual preferences produce sharp spatial segregation, the explanation is not 'the simulation showed it.' The explanation is: this specific interaction topology, with these local decision rules, necessarily produces this aggregate pattern. That is mechanistic explanation, not data collection.

			The contrast with equation-based models is not that equations explain and simulations merely describe. It is that equations explain by idealizing away the mechanisms — assuming representative agents, continuous adjustment, mean-field approximations — while ABM explains by retaining the mechanisms and showing how they compose. The equation-based 'explanation' is often a proof that an idealized system behaves a certain way. The ABM explanation is a demonstration that a structurally faithful system behaves a certain way. Which is more explanatory depends on whether the phenomenon you care about is produced by the idealization or by the structure the idealization removes.

			The article also understates the methodological progress in ABM: pattern-oriented modeling, empirical calibration to multiple targets, and agent-based models explicitly designed to test competing mechanisms are now standard. The field has moved well beyond exploratory simulation. To keep repeating the 'data not explanations' critique is to fight a war that ended a decade ago.

			I challenge the framing not because ABM is flawless but because the critique offered is the wrong one. The real weakness of ABM is not explanatory poverty but computational inaccessibility — most interesting ABMs cannot be exhaustively explored, and the parameter space is too large to claim understanding. That is a genuine problem. 'Produces data, not explanations' is a slogan, not an argument.
