Will truth emerge?

In class, the question "how will a work's true aesthetic judgment be revealed?" was posed. To this, Johnson replied, "truth will emerge," echoing the words of Scottish philosopher David Hume. This references Hume's belief that, over time, true aesthetic value is achieved in a work of art through its endurance. This is a point upon which I find very interesting. In class, I refuted Hume's statement, questioning how popularity and time can support true aesthetic value if most people are biased critics. There is one possible outcome that I can gather; the population is actually biased to believe the true, "unbiased" perception. This brought up voting and, as Johnson pointed out, a vote for the right candidate for the wrong reason is the wrong way for a president to be elected. It is with this spirit that I question the previous conclusion on determining a piece's aesthetic values, and I offer my question to you, my classmates:

Will the truth emerge through unbiased mediums?

The situation of the population achieving a true, united perception above is, of course, biased. For truth to emerge, the common notion would have to be on an individual basis. Hume argues that we perceive through our sensory experiences, and our past experiences influence future instances. From this and other sentimental readings by Hume, I've concluded that taste (judgments and opinions) is subjective, and I believe that Hume, an empiricist, would concur. If taste is subjective, however, then a unified taste would have to be, at least on some level, objective. Is it possible to accumulate many individual opinions using an unbiased method, all the while making sure the opinions themselves unbiased?

Now let us consider popularity. To be popular, you must have many followers in a sense, or be well known among the population in consideration. In Hume's texts, he speaks of the unbiased individual whose judgments are the "standard of aesthetic taste and beauty." He says "few are qualified to give judgments on any work of art . . .." If few can correctly judge art, then how can an opinion of reputable art gain popularity through an unbiased medium?

These are simply my thoughts. Refer to any or all of my questions in your responses. Thank you all!
