Yep, but it's mainly ignored. There is also something
called "schedule pressure". If you are playing noughts
and crosses, (USA: "tic tac toe") I recommend that you
don't play your first move until you have figured out the
whole game. I suggest you try chess.
Trying to understand everything before you start is very
often a recipe for not starting. All the programs we see
are ones where someone started. Sometimes, we see
where things are going. Sometimes we play what looks
like an interesting move and see what happens. Ten
moves later we may be wondering, "how did we get here?"
