kneejerk

Automatic, not considered

Kneejerk describes an automatic, unthinking response—like the reflexive leg kick when a doctor taps below your kneecap.

A kneejerk reaction happens without deliberation or analysis: His kneejerk response was to blame the media.

The term usually carries a dismissive tone, suggesting the response lacks thoughtfulness.

Also spelled knee-jerk.
