Yes, sorry, of course you meant that aspect. But the term remains too slippery, too far away from its real content - as can be apparent already in the stats you mention: first of all they are about a public expression, which are reasonably lower in some demographics for more reasons, and secondly they conflate very different phenomena (such as a very ambiguous idea of attributed "importance" vs the subscription to some dogmatic details).

There are also other reasons why you see different behaviours in doctors and nurses: already linguistically, the "nurse" "nourishes", the "doctor" remains the "learned" - one has a direct rapport, the other detached, out of the basic role construed. It just follows that the nurse more probably consoles and the doctor more probably communicates flatly.
