My view and reasons for them. Atheist and Christians welcome here. (short)

[Quick]

I think due to the lack of grasp on reality that we have as a species that this influences our effectiveness or lack there of in determining what is fact. I think we can know some things but that is limited to our perception/brain/tools. I think we have bias because of our limitations and that what we think we are measuring might be things that we want to happen anyways, again due to our bias because of our limitations.

Of course our knowledge of reality is limited, and imperfect. But that does not mean that we don't have some tools to evaluate claims.

The fact that we don't have a perfect grasp of reality, does not mean we should throw up are hands and just believe anything that makes us feel good, or seems to fit our subjective interpretations.

The scientific method seems to do a pretty damn good job of eliminating biases, presuppositions and preconceptions.

Human life expectancy has doubled in the last 100 years, we fly on planes, use cell phones, travel to other planets, etc, all based on evidence based science. Zero faith was involved.

Sure, the scientific method can eliminate a lot of biases we hold but where we disagree is that we are always going to be biased towards things no matter how much we do end up figuring out.

For the other stuff, again, I think you are equating evidence with direction and I don't think the two go hand in hand. I would obviously go to the hospital if I needed surgery, but I consider this an action that is dictated by a priori knowledge since myself and everyone I know would do the same exact thing that I would.
