For a critical thinker, the baseline facts come from the person's own direct experience. They have to. For example, I probably wouldn't 100% believe that hundreds of people can cross the sky in a metal tube (i.e., modern jet airplane) if I had only been told about it. But I've seen it myself. Another example: I've learned enough about technology to think the moon landings were feasible, and I've learned enough about…
Won't relying on direct experience as a basis for critical thinking lead to all kinds of problems due to faulty perception and cognitive biases that we all share? Additionally, how are we to evaluate situations were are not likely to have any experience with? None of us have any experience with, say, the big bang or anything close to what the universe was like then, but can't we still come to many likely conclusions…
Evidence for the big bang ultimately comes from sense data. You have to integrate a lot of sense data into scientific theories, which then are integrated with other scientific theories, and so on. Science has gotten so far - but it all started out with simple experiments, eventually microscopes and weak telescopes, etc. and built from there.
Critical thinking allows you to overcome cognitive biases. Faulty perception is pretty easy to detect. A stick in a glass of water will look bent, but it's easy to figure out that it actually isn't bent.
