What is Critical Thinking?
What's the Church of Critical Thinking?
In addition to religions, there are politicians, pseudo-scientists, psychics, advertisers, and others all asking you to believe things on faith alone without providing clear evidence that what they say is the truth. Our goal is to teach people to use Critical Thinking skills to analyze what they're being told, to be skeptic where appropriate, and to reject ideas that they may already hold as true if they don't hold up when examined critically.
