Definition

Too satisfied with yourself or a situation, so you stop trying to improve or notice problems.

If someone is complacent, they feel comfortable and confident, often too much so. This attitude can make them less alert to risks or less willing to make changes. It is usually used critically to suggest a lack of effort or awareness.

Examples

  • After several easy wins, I became complacent and stopped reviewing my performance data.
  • If you get complacent about cybersecurity, you can miss small signs of a serious breach.

  • They became complacent once the first prototype worked, and the final testing suffered.

Common mistake

Learners often confuse "complacent" with "complaisant" (meaning willing to please), but "complacent" means overly satisfied and not alert.
