Then that needs to change. I'm fine with coining new words for utilitarian purposes, but 'critical thought' is such a semantically transparent umbrella terms for all the things we want to promote — certainly its scope and significance is more immediately obvious than that of 'rationality,' 'philosophy,' 'science,' etc. — that it concerns me how hard rationalists sometimes work to avoid promoting that term. It's cheesier and less edgy in connotation than some of the other terms, but that mainstream valence works to our advantage in some contexts.
