When I think about it, I come to this conclusion:

Knights are not meant to be intelligent. Nor are they, as intelligent people wouldn't be able to STAND being around such dim-wits. Merlin once mentioned something in this direction when Arthur gave him a punch on the arm, saying that it always makes his knights feel better. Merlin replies to this that his knights can't be very intelligent then, or something like that.

Personally, I think that Arthur meant to make Merlin feel better by punching him on the arm.
