Q:

Dear 100 Hour Board,
What's the difference between irrationality and stupidity?
-feeling stupid

A: Dear feeling stupid,
Irrationality means to be incapable of reasoning; defective in mental power and not based on reason. Stupidity is to be dull in mind; showing or resulting from dullness of mind. So you can be irrational but not stupid. It does happen.
