It's logical overall and might overlap with the real life situations.
But still there would be a lot of exceptions. Besides, isn't it again down to what do you understand from smartness or intelligence etc. The study may do some definitions for itself but how it expands into the real life, I'd have doubts.
A very smart guy to make a great example would be James Randi. Even though he is extremely self confident with his notions, he is still open minded as they come. He is a great mind with a proud confidence but, I'd say he would still ace any tests like this one.
