No apology necessary, bart, and I don't think you misunderstood my question. But the whole "framework of interpretation" thing bothers me. If my framework can allow for a 50% error rate, what does that say about my framework as a whole?
It says that the working theory is based upon limited evidence and that the variations in the conclusions are much more volitile than for instance, a theory that is based on a much larger body of evidence, observed and/or examined over a much greater period of time. It also says that comments by scientists and perhaps also those who are quoting them often overstate the certainty that they have. That's especially true in the news environment. There's a huge difference in many cases between what is being said on the cutting edge (which usually goes into newspapers and journals) versus the greater body of substantiated and confirmed information that is going into textbooks. (Not to say that there isn't bias or overstatement there too at times.)
Now, I don't want to go on and say, "So see! ALL of science is bunk!" What I will say is that this is exactly why I am 100% not impressed with scientific arguments of any kind. As I don't have the expertise to look at the numbers myself and come to my own conclusions, everything I could possibly believe on this is from authorities, and if the authorities themselves offer an interpretation that can be 50% off, that's not very comforting. Further, it's plani dishonest. They did NOT say that the divergence happened 200,000-700,000 years ago. They said, "About 500,000 years ago." And who is to say the error rate is not even greater?!?
No argument there. A healthy skepticism is needed by anyone approaching these issues in my opinion. Plus, as we both know, there are other elements in a person's framework that can draw from areas that are decidedly not scientific. On questions of origin for example, it can make a difference whether the person is coming from a philosophical perspective of methodological naturalism versus a general perspective of theism as to how strongly or in what context they'll word their observations.
Perhaps its not the scientists themselves who are being dishonest (or lazy) so much as it is the reporting. And perhaps the dishonesty itself isn't intentional--perhaps it is just laziness on their part. In any case, I'm forced to wonder how much lazyiness/dishonesty there is out there on this kinds of issues.
Communications are driven by agendas and especially in the realm of journalism, controversy or perceived controversy is part of what sells newspapers or draws the attention necessary to sell advertising. I think a healthy skepticism is a very valuable thing. Where I think it becomes counterproductive is when it crosses the line in cynicism and imagines that science is huge conspiracy trying to give religion or christianity a black eye. That does exist, but it's a relatively small subset and many in the realm of science are both Christians themselves or seeking to be responsible and reasonable in their work and conclusions.
Science is still comprised of humans and there's not any doubt in my mind that overstatements happen.
