Confusing Words

credible vs credulous

These two adjectives are confused because they share the Latin root credere ('to believe'), but they apply to different subjects with opposite values.

  • credible — credible describes a source, claim or person that is worthy of belief — reliable, convincing and trustworthy; for example, ‘The researcher cited a credible study published in a peer-reviewed journal to support her argument.’
  • credulous — credulous describes a person who is too willing to believe things without sufficient evidence — easily fooled or naive; for example, ‘Only the most credulous reader would accept the narrator's account without questioning his motives.’

Memory rule: A key distinction: 'credible' refers to what is believable; 'credulous' refers to someone who believes too easily. In academic writing, you might describe evidence as 'credible' and a reader who accepts weak arguments without question as 'credulous'.
