dunderheadedness
Complete mental thickness
Dunderheadedness is the quality of being a dunderhead—a blockhead or stupid person.
The word emphasizes persistent, thick-skulled foolishness rather than a momentary lapse: The sheer dunderheadedness of the decision cost us the contract.
It's mildly humorous and old-fashioned, more exasperated than cruel.
