One problem with pitching "rationality" is that implying that someone lacks rationality puts them on the defensive; it sounds as though you're trying to bring people from below-baseline up to baseline, rather than from baseline to a higher level. I've gotten better reactions when using the phrase "advanced sanity techniques". Suggesting that someone study them conveys the existence of a higher level, without being perceived as a status attack. I think that if the name is descriptive, it's important that it contains something ("advanced" or an equivalent word) which clearly communicates the fact that it is not aimed at low-status people.
