Sorry but no high-school kid is capable of combing a textbook, distilling out thousands of facts contained within it, informed enough to be able to fact-check them all (no, Googling everything is NOT sufficient; a thorough familiarity in the field is required in the first place, in order to make the most of the research), and then capable of generating a proper statistical analysis of the data he's tabulated.

This is the sort of thing that entire TEAMS of college-educated ADULTS do ... and take months to accomplish, if they even finish. Whole think-tanks like Heritage Foundation have analyzed textbooks on occasion, probing for bias ... and none of them found any, that I've ever heard of. All they can do is cite isolated quotations which amount to anecdotal evidence, rather than a properly-devised statistical calculation of "bias" based on thousands of data.

And none of this even begins to overcome the inherent problem of defining and specifying "bias," given that it's almost always a subjective whine in the first place.

Sorry, but I'm neither stupid nor naive enough to believe that a lone high-schooler could even begin such a project, let alone complete it. Especially if think-tanks have never come close to such a thing.
