Not a resource per se, but here are a few friendly bits of advice that have been very useful in my own pursuit of critical thinking: Always be skeptical (skeptical, not cynical) of everything. Always demand evidence that can you independently verify (and be extra-skeptical of anyone claiming to have "secret evidence" that you aren't allowed to personally scrutinize). Always be congiscent of the fact that the number of people who hold a position or tout of a belief has absolutely no relation to the veracity of that position or belief. As social beings we are predisposed towards groupthink. Widely-held positions and beliefs seem inherently more credible because of their widepsread acceptance. They aren't. Always be especially skeptical towards information that seems to support and/or reinforce what you believe. Humans are also innately predisposed to conformation bias. Try to be aware of this innate predisposition when scrutinizing evidence that supports beliefs. Beware of certainty. Always remember that we are imperfect beings. Our brains, our thought processes, our memories are all fallible. Our understanding of the universe is limited and there is far more we don't know, than what we do know. There's a critical difference between being "certain" about something, and being "as certain as you can be" about something. While this sounds like a semantic difference, it most definitely isn't. Always remain constantly aware, that as convinced as you may be of something, you could be wrong.
