According to the methodological principle called ‘robustness’, empirical evidence is more reliable when it is generated using multiple, independent (experimental) routes that converge on the same result. As it happens, robustness as a methodological strategy is quite popular amongst philosophers. However, despite its popularity, my goal here is to criticize the value of this principle on historical grounds. My historical reasons take into consideration some recent history of astroparticle physics concerning the search for WIMPs (weakly interacting massive particles), one of (...) the main candidates for cosmic dark matter. On the basis of these reasons, I assert that robustness, at least in this historical case we are considering, has less value than usually assumed by philosophers. (shrink)
