Well we have empirical evidence.
You mean subjective experience of that empirical evidence.
Right (on biases), but we can acknowledge that such biases exist and we can do our best to be as unbiased as possible. Scientific inquiry and peer review minimize such biases. If they didn't we wouldn't be capable of any advanced technologies.
Any individual cannot do it.
The collective knowledge of humanity, acquired by the peer-review process, is as unbiased as we can get, and is indeed what it's purpose is.
But that collective knowledge is not the same as an individual's beliefs. None of my beliefs inherently contradict any of that knowledge, at least as far as I'm aware, nor are those beliefs intended to fill in any of the gaps of that knowledge.
And we've been able to create advanced technologies without it in the past. One of our inherent traits is tool-usage.
Ok, I could qualify the OP by saying "those religions that require supernatural belief" - but isn't that the lion's share of all religions? In any case - I'm happy to make that qualification, it was the belief in the supernatural that I was claiming adversely affects critical thinking.
That would be better, although I would still disagree that it inherently does so.
And I would also ask, if empirical evidence is so important, what's the empirical evidence that this claim is accurate to reality?
