Correlation between #$%@ and movie ratings

I came upon a scholarly article relating to an experiment created by two Harvard Professors. The professors wanted to see if the amount of profanity in movies was related in the the movies actual rating. By viewing hundreds of movies on all rating scales they rated them according to the profanity used. According to their findings the current ratings given on movies are not necessarily accurate. For example the fact that the movie has a pg13 rating does not mean it possesses more profanity than a G-rated movie, and vice versa.
This article goes hand in hand with the, "Freedom's Curse," article because they both touch on the subject on how much profanity should be displayed in the media. The scholarly article relates to the The Atlantic article in an different way. Meaning the Atlantic article spoke of how certain shows with more profanity are only displayed at certain times. The times are supposed to be when most children are not watching TV. This may not be true though because according to the Harvard researchers findings they suggest that the movie ratings are not completely accurate. With this said that means that the shows playing during children hours may have significant profanity. Since I am an 18 year old college student I do not find the profanity shown on TV to be offensive. However I can remember times when I was younger, and certain things said on TV caused me to wince. Therefor television should continue their monitoring of television programs shown at certain times. Even better is that fact that available today are parental controls. This allows persons who want to watch more profane TV the chance without compromising our children.
