On a personal note: I also use have a default preference for OO 
when that makes it possible to avoid documentation because the 
implementation has a 1-1 correspondence with the model. Then you 
don't have to deal with out-of-date documentation and the boring 
task of writing documentation.

This is also desirable when you evolve software rather than plan 
it (experimental prototyping or simulation). If you expect a lot 
of successive changes then documentation becomes a real burden.
