Defuzzification - center of gravity

I'm writing my dissertation work (or however that is called in english)
about a fuzzy logic related topic and have a special question about the
center-of-gravity method for the defuzzification.
The influence of an area is big when its aera is big. The area is big
when it is high and wide. But the wideness represents the uncertainty of
the value. My question is: Isn't it wrong that uncertain fuzzy sets have
more influence and fuzzy sets with a more or less exact value have only
very little influence to the result?
