Exploring and extending the landscape of conjunctive approaches to verisimilitude

Starting with Popper, philosophers and logicians have proposed different accounts of verisimilitude or truthlikeness. One way of classifying such accounts is to distinguish between "conjunctive" and "disjunctive" ones. In this paper, we focus on our own "basic feature" approach to verisimilitude, which naturally belongs to the conjunctive family. We start by surveying the landscape of conjunctive accounts; then, we introduce two new measures of verisimilitude and discuss their properties; finally, we conclude by hinting at some surprising relations between our conjunctive approach and a disjunctive account of verisimilitude widely discussed in the literature.
