The elastic nonveridicality property of indicative conditionals

Abstract

Indicative conditionals are known to have the semantic property of nonveridicality, that is, they do not entail the truth of the antecedent. In this paper, I argue that the nonveridicality property of indicative conditionals is elastic in that it can be affected by the choice of conditional connectives and negative polarity items. Two experiments are reported, one on German and the other on English. They show that in both languages, the presence of negative polarity items conveys a weakened speaker commitment towards the antecedent, although there is cross-linguistic variation concerning the effect of conditional connectives.
