The linguistic diversity of truth and correctness judgments and the effect of moral-political factor

In this paper, we will report results of two sets of cross-linguistic studies about truth judgments and correctness judgments by speakers of English and Japanese, which will show a significant influence of a moral-political factor in an utterance on Japanese truth/correctness judgments. Following up Mizumoto (2022), which demonstrated such an effect on Japanese truth judgments and correctness judgments about utterances containing a contrastive conjunction (such as “but”), Study 1 shows the same effect on Japanese correctness judgments about utterances containing a pejorative. Study 2 then shows that a moral-political factor in utterances can affect Japanese truth/correctness judgments about them even if they are simple utterances containing neither a contrastive conjunction nor a pejorative. In conclusion, we will briefly discuss whether this effect is linguistic or psychological, and present three hypotheses: the semantic hypothesis, pragmatic hypothesis, and error theory hypothesis, to account for the data, which we leave open for future studies.
