I think that 'critical thinking' is another label that gets misinterpreted. It gets confused with criticism and also with debunking. Not that there's anything wrong with either of those.
Critical thinking is not about criticising things for the sake of it, it's a mode of thought that, ideally, leads to the truth in matters. It's about the intelligent processing of information rather than simply accepting information.
It's a wide area without a single, easy definition, but I think it's the use of rationalism, logic, recognising logical fallacies, evaluating and explaining ideas and information.
Skepticism is about finding the truth in matters, so critical thinking is an essential piece of kit in the skeptic's toolbox.
