Same reason some people vote for a candidate based on what party they belong to instead of if they are the best candidate for the job in question.
It's stupid, but human, I guess.
I know I'm biased against certain genres, so I tend not to give ratings on most FPS/3PS shooters or sports games unless one happens to grab my attention somehow(Like Prey and Bioshock did). Sites with a rating system like this one has would be more reliable if more people did the same, but it ain't gonna happen.
