Moving subconscious processes into the conscious realm increases control, and control can be good.
But control doesn’t always produce the best art (writing or otherwise). A state of flow is not usually a state of conscious control. The right balance between letting go of control and staying in control while writing will (on the evidence I’ve seen) vary greatly between authors.
IF is also not a medium that’s especially well-suited to authorial control, as we’ve talked about in some past forum conversations:
The more complexity you add to your IF work, the more likely that people will find stories in it that you didn’t write, even though you wrote all the words.
