I am talking about people whose maps are not even approximately correct, but they still keep them because... I am only guessing here... they still provide emotional comfort.

Two points. First, a very important word here is "matters". A lot of maps don't matter. If I believe that there are adepts meditating in secret caves in Tibet and they have direct access to the the Akashic records and so can see into the future and into the past -- so what? Does that affect my life in any way? (note, by the way, the difference between "could matter" and "does matter").

Second, an incorrect map is also known as "fiction". That makes for an interesting connection to the parallel thread about the use{full|less}ness of fiction.
