No way....a 4.0 just tells you that a person did really well with their course load, not that they were Ted Kaczynski wannabes.
I still remember the smartest person I ever met (I would be willing to bet that he'd do pretty well on any math test - Putnam included - you gave him). This fellow had the highest GPA in electrical engineering and also had the second highest GPA in economics. Simultaneously.
And on the side, he was an active skydiver and practiced jui-jitsu 2x a week. And over the course of the 4 years we spent in undergrad, I don't think I ever saw him study (I'm not exaggerating).
So it is possible to be off the charts intelligent and not be anal retentive or unbalanced.
