Yes, there is such a school.  Those people are full of bovine excrement.

Documentation should describe intent and interface.  Yes, the code says 
what the code does.  But, the interface description says what it's 
supposed to do.  Can the docs be wrong?  Of course they can.  Usually 
because somebody changed the code and didn't bother to change the docs.

My take on people who never document anything is that they're just plain 
lazy.

Go ahead, ask me how I really feel about the topic :-)
