Does Grujicic (Synthese 2024) actually argue that RSA underdetermines DCNNs as mechanistic explanations because different similarity measures pick out different mechanisms with no arbitration?

Grujicic's DCNN critique is framed on Craver & Kaplan's model-to-mechanism-mapping (3M) requirement and the how-actually/how-possibly distinction, not on Marr's levels — the word 'Marr' never appears in the paper

In Grujicic's account, correlation and Euclidean distance pick out different representational vehicles, so RSA's choice of similarity measure selects which mechanism-type is being compared

Different similarity measures can reverse which neural representations count as most alike, with no settled basis for choosing among them

Is 'arbitration' the general missing ingredient across the vault's underdetermination cases? RSA similarity-measure selection and the bridge=gap reading

Representational similarity underdetermines shared mechanism — matching a target's output does not fix its underlying mechanism
