This was pretty common in sf of the early 20th century, actually — the trope of a special group of people with unusual mental disciplines giving them super powers and special moral status. See A. E. van Vogt (the Null-A books) or Doc Smith (the Lensman books) for other examples. There's a reason Dianetics had so much success in the sf community of that era, I suspect — fans were primed for it.
