Output improves when decisions happen before urgency chooses for you.

Decisions made in advance are made by you. Decisions left until the pressure arrives are made by the pressure, and they tend to favour whatever is loudest, nearest, and most immediately relieving. The quality difference is not about intelligence, it is about when the choosing happened.

Set the important decisions of your week before the week starts. What gets your best hours, what you will decline, what waits. Then urgency has less to choose from.
