I'm old enough to have been here and sentient in the times before the internet. I remember when the only place for these kinds of discussions and debates was in what was called "newsgroups".
There was much discussion and anticipation about how access to information would affect society, and political debate. I remember thinking in those days that getting so many opinions from such a large number of people would lead to solving some problems, or at least some changed minds. Yes we were all that naive.
After the World Wide Web, as it was originally called, came into being we found that we could back up our statements with facts from individuals in authority on just about any subject. In this we were right BUT, as it turns out, the individuals in authority most often don't agree.
All branches of science, including the sciences of economics, psychology, history, medicine, and even the "pseudo-sciences" have a multitude of people putting their ideas, opinions, data, theories, and results out on the internet. You can find people in authority, people who have actual degrees in their fields who spount all kinds of ideas.
ANY internet blogger, or messageboard debater can find someone in authority who will back up anything they need. It doesn't matter what your stand is, you can believe in sasquatch and find a scientist who agrees, you can believe in exratereestrial visitation and find the same thing. Ditto with truthers, creationists, global warming believers, and on and on.
Now, my purpose of starting this thread is not to debate any of those topics that have been debated to death (without either side giving an inch), but to discuss whether access to so much information has actually helped anything.
