The user is stupid?

I am sure that every webdesigner met the "user is stupid" problem: most of the solutions are not accepted as they (the clients) think that they are not obvious enough. Usually I try to handle this problem empirically: everybody can be conviced with statistics. On every single webpage administered by me near the icons there is a text version, so I can analyze only one case which is similar to the icon without the text. I come to really interesting conclusions.

On the tech site iSITE.hu there is under each post an icon with the „Share this!” text. The icon speaks for itself, as refers to the social relationships with dots connected to each other. The text is in English, so for many Hungarian users it is only an image, and it is less speaking for itself. In Hungary only the 20 percent of the population speaks English (according to the latest official statistics from 2000: 18%). We can presume that due to the specific social status of the internet users, this percentage is a little bit higher. I couldn't find a statistics about that, so let's presume that is around 50 percent. Now we can say that to the 50% of the visitors of the iSITE.hu practically only the icon can be useful. But the stupid users prefer it instead of neglecting it - contradicting the overwhelming opinions and predictions.

They click on it, and not just accidentaly, they are ten times as many, as those who click on „Tovább” [Read more] or on „Új hozzászólás” [Add a comment], which are a combination of text and icon (moreover, there are only 4 more popular links on the whole site). If only the visibility and intelligibility would count, then there should be more of those who click on the Hungarian text links. But we saw that there is no direct connection between the number of clicks and intelligibility..
The "stupid users" want to find out more often what is a misterious link, than an obvious one. I must admit, that the users often behave surprisingly conservative, they find the menu only on the left side of page, they think that every link should be underlined, they want (fortunately today this almost disappeared) to find the functions (bookmarking, printing, go to previous page, etc.) built in the browser on the web site, too. A designer should take that into consideration, because the user might get frustrated and never return to the site. I cannot deny this, but my example proves that conservatism may go in hand with extreme curiosity. And we could build on that.
Is it possible, that the "user's" behaviour is like a child's?
