From: the study of the philosophy of knowledge, from extensive experience with the scientific method, and from knowledge of cognitive science.

That is, I come from a perspective of practically all the collected human knowledge of how to answer questions like these. I don't know all the collected human knowledge on the topic, but I know a good deal. The reason I'm not engaging with the sweeping general statements you've made is that the same type of sentiments have been offered many times before, discussed to death, and found to be lacking, both logically, and empirically. And there aren't any specific pieces of evidence you're bringing to bear that might be novel, so I can't engage with that: I requested it, but it's not forthcoming.

We're not getting anywhere, so best to just stop. Any readers can make up their own minds (though admittedly it will be hard to evaluate my perspective without a little bit of background in epistemology or, maybe, cognitive science/psychology/etc.).
