Protect the list from same-day additions

Don’t add new items to today’s list when they arrive — log them for tomorrow’s planning instead.

Why it works

New tasks arriving during the day are inherently high-salience: they feel urgent because they just happened. Without a rule, new arrivals push earlier priorities down regardless of their actual importance. The rule "new arrivals go to tomorrow’s evaluation, not today’s list" protects the morning’s prioritization decision from being overwritten by the day’s urgency cascade.

How to do it

1. Keep a separate capture area for items that arrive during the day (a notebook page, a sticky note, an app inbox).
2. Do not move anything from the capture area to today’s active list until the current task is done.
3. At the end of the day, review the capture area during tomorrow’s planning — most items that felt urgent will need less attention than they seemed.

Evidence

The urgency bias (Zhu & Yang 2021) predicts that newly arrived items will feel more important than they are relative to pre-committed priorities. Separating capture from execution is a standard behavior-design principle that protects prioritization decisions from in-the-moment distortion. (mechanistic)

Applies to discretionary work; genuine emergencies requiring immediate action are a legitimate exception. The practice is about interruptions, not real crises.

Common mistake

Checking email or messages at the start of the workday before working on task one — inbox items immediately generate urgency pressure that distorts the priority sequence.
