thickheadedness
Stubborn cognitive slowness
Thickheadedness is the quality of being slow to understand or stubbornly obtuse.
It suggests mental density—someone who can't grasp what's obvious to others, or who refuses to: His thickheadedness about the deadline cost us the contract.
The word carries impatience or frustration toward the person described.
