The mind has developed vigilance mechanisms that protect individuals from deception and misinformation (Sperber et al. 2010). They make up a module that checks the reliability and believability of informers and information. Vigilance mechanisms may also comprise a sub-set of specialised mechanisms safeguarding hearers from interpretative mistakes conducive to misunderstanding by triggering an attitude of hermeneutical vigilance (Padilla Cruz 2014). This causes individuals to check the plausibility and acceptability of interpretative hypotheses appearing optimally relevant. Relying on empirical evidence, this paper characterises this subset of mechanisms and suggests some avenues for future research.
