  Another approach to EOCS is to ground it in the practical aspects of the craft of modeling and simulation. According to this view, in other words, the best account we can give of the reasons we have for believing the results of computer simulation studies is to have trust in the practical skills and craft of the modelers that use them.  A good example of this kind of account is (Hubig and Kaminski, 2017). The epistemological goal of this kind of work is to identify the locus of our trust in simulations in practical aspects of the craft of modeling and simulation, rather than in any features of the models themselves. (Resch et al, 2017) argue that a good part of the reason we should trust simulations is not because of the simulations themselves, but because of the interpretive artistry of those who employ their art and skill to interpret simulation outputs. Symons and Alvarado (2019) are also critical of this approach, arguing that “Part of the task of the epistemology of computer simulation is to explain the difference between the contemporary scientist’s position in relation to epistemically opaque computer simulations..” (p.7) and the believers in a mechanical oracle’s relation to their oracles.  Pragmatic and epistemic considerations, according to Symons and Alvarado, co-exist, and they are not possible competitors for the correct explanation of our trust in simulations--the epistemic reasons are ultimate what explain and ground the pragmatic ones.
