A specific subtrope of Flanderization
(and occasionally Jerkass
also). As a series progresses, characters sometimes become more and more stupid as time goes on. Usually the reason is related to the Badass Decay
phenomenon, but with the character's level of intelligence rather than his ability to kick ass, following something along the following cycle: an episode in which the characters acts like a total buffoon gets good ratings, so another one is made. It too gets good ratings. So they make another. And another. Eventually the character is so dumb that you wonder how he manages to walk across a room without injuring himself, and pretty soon everyone forgets that the character was anything other than a complete moron. For this very reason and the fact that it's easier to write comedy that involves dumb people, this trope is rather frequent in any comedy series.
Generally Played for Laughs
. Sometimes used on the supporting characters to make the hero look more competent. Or sometimes, it's just that the show gets a pack of new writers and they turn the guy into a moron for kicks. It should be noted that this isn't always a bad thing
. In some cases, viewers may find the over the top idiocy more entertaining than the original concept, or that giving them some idiotic traits make them more of a Rounded Character
characters seem particularly prone to this; it is very easy for writers
to go from 'savvy but unintellectual' to 'just stupid'.
