I am still not very impressed with Google's search engine in this aspect, but it is not biased in the way you suggest.
At least it is not biased that way for me. As far as I am aware, and I might be completely wrong here, Google, in part, bases its search results on your prior search history and other stored profile information. It is entirely possible that your search results say more about your online profile than about Google engine :)
