I like the suggestions so far, but I think they need a few changes.
- I don't think it is (or should be) just about science. It should be about any kind of dubious claim. Including political or historical claims.
- It's ok to question scientific sources, if the claim is dubious or contentious or extraordinary.
- 'woo' is a colloquialism which is more-or-less synonymous with pseudoscience, but less descriptive and more pejorative.
I'm happy for others to edit my answer to make small changes, additions, or clarifications.
Skeptics - Stack Exchange is for skeptics, rationalists, free thinkers and anyone who questions pseudoscience. Skeptics is aimed at applied skepticism, not for philosophical discussions about skepticism itself.
You're in the right place if you have a question about the veracity of claims that don't come from a reputable source, including, but not limited to:
- the mainstream media
- urban legends
- chain letters
Whatever the claim it must be possible, at least in principle, to evaluate it empirically. Questions about the following are considered off-topic, too general or subjective and argumentative:
- the whys and hows of Skepticism itself
- non-factual topics from domains such as philosophy, religious or political belief or theology
Please ensure you provide a source for the claim you're questioning, and details of the claim itself.
You can also ask questions about claims which do come from an otherwise reputable source, if that claim is dubious or contentious or extraordinary. For example, if your doctor claims you must drink 8 cups of water a day, feel free to ask us if that claim is backed by evidence. Or if you see a scientific journal article claiming to provide evidence for ESP, feel free to ask about that too.
However, if your question is prompted by personal skepticism about specific details of a particular field of knowledge, but it is not about a claim which is dubious or otherwise questionable, then please asks the experts of that field. For example, if you are skeptical of the claim that a particular established method of measuring the distance of stars from Earth is superior to another established method, while a skeptic may be able to provide an answer, you're better off asking an astronomer or a physicist.
