Trekkin, it seems hard to argue with your point that journals need operational funding. However, leaving economic concerns aside for a moment due to the difficulty of discovering audits explaining exactly how journals spend their money, lets talk about pedagogy. In response to your example of phylogenetic confusion, wouldn't the act of finding alternative means of funding and enabling open access for all itself promote the practice of fact-checking and give people more opportunity to learn how to properly understand the material presented?
Speaking for myself, I learn by doing. I best learn to understand journal articles by reading them, and yes, I have taken classes in statistics and experimental design. Could this be the source of the difference in our worldview? You seem to think that people must first learn how to read before they can properly read, but I would reflexively contend (due to my learning style and lack of life experience) that individuals learn best by trying. Could our own preferred methods of learning be a source of bias for both of us?
To your first question, it depends, and to your second question, certainly.
It depends on what you mean by "opportunity", really. As an analogy, we both have the "opportunity" to climb Mt. Everest in the sense that the mountain is there and we're technologically capable of reaching the top, but I certainly don't have the time to go to Nepal and actually do that, so I arguably can't despite the opportunity. Likewise, not many people have the free time to conduct literature searches for free, even of the literature they already have available -- especially since it's going to take far longer for people who aren't trained to do it efficiently, and longer still if they have to learn the theory before they can make sense of the data.
The other problem is that, unlike climbing a mountain, there's no obvious place to stop checking your understanding of the facts against the facts themselves. Anyone who reads a paper will come away with some understanding of it, but it might not necessarily square with everything in the paper, let alone everything we know. Further, they will have confidence in their understanding -- and, unfortunately, that confidence scales inversely with the information they used to reach it, per the Dunning-Kruger effect. There are infinitely many ways to be wrong and they all look right at first glance, like with my virus example. I just worry that people are, quite understandably, too busy to go back and have a second and third and fiftieth look for themselves and make sure they're justified in their conclusions.
It's absolutely sensible to learn to read journal articles by reading them; in fact, I don't know any other way to do it. It's just not sufficient on its own, it's not at all a fast process, and not everyone has the opportunity to go through it in the sense of having the time and inclination to do that instead of whatever else they might do.
If we're going to take seriously our obligation to educate the public, we should recognize that it's incumbent upon the educator to simplify the material to suit the pupils so they get some use out of it. When we teach little kids about how plants work, we tell them they need sunlight and water and soil, but not how photosynthesis works biochemically, because it's all meaningless jargon without first establishing how matter works on molecular scales and they don't have the necessary thermodynamics yet. Handing elementary schoolers a paper on the structure of P680 would be worse than useless; it'd just confuse them and make them feel dumb.
Yes, having greater access to primary literature than they already do would lower the barrier to entry for people to understand science, but it's still too high for the average person to spend the time to cross and there's not much of immediate use to them on the other side. There's so much more that needs to be done to make primary literature accessible to the public in a real, useful sense than just handing them shedloads of information -- and, as I said in the last thread and above, there are people who will misuse that access to spread dangerous misinformation in ways that need real understanding to combat.
So if you want to give everyone access to everything, how do you plan to insulate them from their resultant ability to lie to themselves and each other far more plausibly, bearing in mind that access to information and the ability to understand it are separated by a time-consuming and costly educational process that most people couldn't afford even if it were free?
To return to my mountain analogy, yes, right now there's a fence around the top -- but given that the mountain is
covered in landmines with a density that increases as you approach the peak, perhaps there is some sense in insisting that people walk along the marked path up to the gate and take the accompanying minesweeping course or just settle for looking at it. Take the fence away and people will make their own way up, and they're almost certain to tread on a mine and think homeopathy makes sense.
