Rating a cultural thing?

I'm convinced that the culture has a big role to play with rating and even more important with Internet rating. My wife is american and as such we travel a lot to the US. For a European person like myself it is always interesting and "funny" to see the form we have to fill coming to the US. And I'm always wondering if people coming in are honest or not on the check box they choose. So clearly, the cultural aspect of the rating is important and a good and reliable Internet rating system should take this in consideration.

In a nutshell, understanding the culture will make or break an Internet rating system. Thinking that a system could be created in the US and applied in Europe, Eastern Europe, Asia, China without a good understanding of the cultural aspect is clearly an utopia.
