Our attitudes, usage, and behavior datebase is built (see previous post). Will it really be useful? Probably, assuming that the contents of the database are truly representative of bloggers thoughts. So how do we know that bloggers tell the "truth"?
Truth, for simplicity sake, I'll define as a form of accord with facts.
Without delving into the nuances of the Performative Theory of Truth, I shall borrow this from Wikipedia: "to say a statement is true is not to make a statement about a statement, but rather to perform the act of agreeing with, accepting, or endorsing a statement". So, I interpret this to mean, if I agree with (or accept) a statement as truthful, regardless of who makes it, I'm endorsing that statement as being the truth. In other words, I buy-in hook, line, and sinker predicated upon agreement. If you disagree, feel free to correct me.
Pedantic you think (you're right!), how does this answer the question about bloggers and the truth?
In absolute terms, it does not. Of course we're speaking of human beings so we really can't stick to absolutes. Just like you would never assume that in a survey, or in a focus group, you always get the truth. Margin of error attempts to compensate, but you never really know what someone really thinks. You only know what they say they think when you ask them a direct question. Thus the beauty of blogs. People's unsolicited, unfiltered, and direct thoughts.
Read this article in today's WSJ about the power of the Web and how it is "obvious and undeniable". Daniel Henninger muses about the proliferation of thoughts written and spread via blogs. Supporting quote:
"But what if the most potent social effect to spread outward from the Internet turns out to be disinhibition, the breaking down of personal restraints and the endless elevation of oneself the growing disinhibition".
So, people tend to filter less, and spout more, of their personal thoughts on almost any subject. We do get the free assoication and collection of insights that center around peoples thinking. Ultimatley, the only person they might really lie to is themselves.
Here's what I would do. Aggregate the information, look for and connect the dots, test the theory, predict the results. Wash, rinse, repeat.
