It takes a kind of understanding of Torah to see that many Torah scholars are in fact just playing a game of pretending to be Torah scholars--and people believe them. Thus it is not unusual to find in the religious world that most of the leaders are stupid though they pretend to be Torah geniuses. It is all an act. On the other hand there are the great Litvak yeshivot like the Mir in NY where in fact the roshei yeshiva were very smart. However the religious world has leaders that are basically stupid but play act with the right gestures.
The sages themselves mention this problem in GemaraShabat and Rav Nahman mentions this issue in his LeM concerning Torah scholars that are demons. Lem vol 1. chapters 12 and 28
