This chapter focuses on one element of causal complexity: disjunctions, or equifinality. Using an example from applied research, it is explained which new SMMR principles and subtypes of cases need to be formulated to capture the consequences for descriptive and causal inference triggered by disjunctions. Learning goals: - Understand the inferential challenges triggered by disjunctions (equifinality) - Get acquainted with the additional sub-types of cases produced by disjunctive solution formulas - Understand how additional principles guide case selection in the presence of disjunctions - Learn if and how moving up the ladder of generality can be used to theorize away disjunctions and the inferential challenges it poses - Become more familiar with the smmr() function and the interpretation of its output in the presence of disjunctions
