Jeopardy Intelligence Test

A device employed by writers to demonstrate that a character is particularly intelligent or knowledgeable. A character (often the TV Genius) will be shown watching a game show on television and instantly blurting out the correct answer to every question. May be played for laughs if the questions are obscure and esoteric to the point of absurdity.

In America, the game show is most likely to be Jeopardy!, as it has garnered a reputation for being the most difficult of the popular game shows, not to mention because of its distinctive, relatively fast-paced game structure. In the United Kingdom, the notoriously difficult, long-running University Challenge fills this role.

Of course, it should go without saying that trivial knowledge has little relation to intellect, but this is just a quick and easy way for writers to establish a character as smart.

A common subversion is for the character to have watched the episode before and memorized all the answers.

Examples of Jeopardy Intelligence Test include:

Advertising

The Taco Bell dog successfully pulls this off in one of the campaign's earliest commercials.
A Coca-Cola ad played in movie theaters features a large, stereotypical trailer-trash woman watching Jeopardy! and getting all the right answers. At the end of the commercial, she rewinds the tape and starts watching it again.
Armed Forces Network had an ad of two guys watching Jeopardy! at night with one of them getting all the answers correct. The other guy wasn't amused. This ad meant to tell there's an alternate station for people living in the Atlantic zones who can watch during the day. Atlantic channel has the exact same programs as the Pacific. These two live in the Pacific region watching Jeopardy! on Atlantic network at night (one had already watched it on Pacific).
