Around 1876, the sudden involuntary extension of the leg in response to a light blow just below the knee, which is also known as the "patellar reflex," was given the refreshingly simple designation "knee jerk." In the 1950s, "knee-jerk" became an adjective with a figurative sense that doesn't require any actual twitching. "As a salesman, I'm getting a bit weary of the knee-jerk association of a con artist with my professional calling," a correspondent once wrote to The New York Times Magazine. "Knee-jerk" often has a negative connotation. It usually denotes a too-hasty, impulsive, perhaps even irrational response that is often based on preconceived notions.
