Abstract

Current cosmological observations place little constraints on the nature of dark matter, allowing the development of a large number of models and various methods for probing their properties, which seem to provide ideal grounds for the employment of robustness arguments. In this article, the extent to which such arguments can be used to overcome various methodological and theoretical challenges is examined. The conclusion is that while robustness arguments have a limited scope in the context of dark matter research, they can still be used for increasing the scientists’ confidence about the properties of specific models.
