Well, the thing about anxiety is that it's very irrational. Unless you've suffered from it or, like me, are very close to someone who does, it's very hard to understand. (I still have only a surface level understanding after a 10 year relationship with a sufferer.)
It's easy to look at all of the things taking a test and fixing code in an emergency have in common and make the rational assumption that someone who is bad in one situation would be bad in the other.
