PL/SQL conditionals with NULLs

We were wondering if there was a reason why Oracle's tools generate some conditional statements this way:

  IF NOT( variable IS NOT NULL) THEN .....

From our stand point, this seems a bit counter intuative. Is there are reason why, by default, the tools generate conditions this way?

Also, is there a FAQ floating around that we can get at?

Thanks!
