Plural of credulity; instances of being too willing to believe things without good evidence or proof.
From Latin 'credulus' (trusting, easily believing) plus '-ity' (the noun suffix). Paradoxically, words from 'credere' (to believe) can mean both healthy trust and foolish belief.
It's wild that 'credibility' (deserving trust) and 'credulity' (being too trusting) come from the same Latin root but opposite meanings—English needed both to describe trust and foolishness!
