In a nutshell, the idea is that if in one of two test situations, which are homogeneous with respect to instantiations of unmeasured constituents of a scrutinized phenomenon Ψ, a change is induced on a mereological part Φ of Ψ such that Ψ changes its value while both Φ and Ψ remain unchanged in the other of the two test situations, it can be inferred that Φ is a constituent of Ψ. However, the fat-handedness of all experimental manipulations of different levels of mechanistic systems inevitably yields that attempts at generating conclusive evidence for constitutive relations are bound to fail. Even in laboratory contexts that are perfectly homogeneous with respect to unmeasured factors that (causally or constitutively) determine a phenomenon Ψ, it is impossible to generate unconfounded data on constitutive relations. As a result, the inference to constitution is systematically underdetermined by evidence. What is more, empirical underdetermination affecting constitutional inference differs from empirical underdetermination as is known from causal inference. Empirical data can often be accounted for in terms of different causal models that fare equally well with respect to all parameters of model fit (cf. e.g. Spirtes et al. 2000, 59-72; Eberhardt 2013). Such underdetermination ultimately stems from the complexity of causal structures in the world we live in and from our limited capacities for controlling background influences in ordinary discovery contexts.
