The present paper is devoted to present two pragmatic logics and their corresponding intended interpretations according to which an illocutionary act of (scientific) hypothesis-making is justified by a scintilla of evidence. The paper first introduces a general pragmatic frame for assertions, expanded to hypotheses, AH and a hypothetical pragmatic logic for evidence HLP. Both AH and HLP are extensions of the Logic for Pragmatics, LP. We compare AH and HLP. Then, we underline the expressive and inferential richness of both systems in dealing with hypothetical judgements, especially when based on different, sometimes conflicting, evidence.

Abstract
The present paper is devoted to present two pragmatic logics and their corresponding intended interpretations according to which an illocutionary act of (scientific) hypothesis-making is justified by a scintilla of evidence. The paper first introduces a general pragmatic frame for assertions, expanded to hypotheses, AH and a hypothetical pragmatic logic for evidence HLP. Both AH and HLP are extensions of the Logic for Pragmatics, LP. We compare AH and HLP. Then, we underline the expressive and inferential richness of both systems in dealing with hypothetical judgements, especially when based on different, sometimes conflicting, evidence.
