I have seen it called "structured procrastination".
The idea is that instead of trying to focus on what's important, leaving out everything else, make a long task list, including things that are not that important, but still productive. So that you have plenty of things to do to avoid doing the top items.
To avoid shifting the problem, it suggests self-deception, so that you put items on top that appear important, but are not really. So that you do the really important ones in order to avoid doing the falsely important ones.

I don't know how effective it is though.
