Why a pause can help an unfinished problem

When work stalls, the first attempted solution can become a rut. An interval spent on something else may weaken that fixation; later, a neglected association becomes easier to notice. Experiments grouped under “incubation” sometimes find better creative-problem performance after a break, especially when the intervening task is undemanding and the original problem has already been engaged.

The effect is variable, and a break is not secret labour that guarantees an answer. Rest can also become avoidance; many real creative tasks differ from laboratory puzzles. The practical claim is deliberately small. Define the snag, leave it for a bounded interval, then return and generate alternatives before judging them. The pause changes the conditions for another attempt; it does not replace one.
