Check Your Decision Tank
Important decisions deserve a full tank, not the fumes.
Before making any important decision in the afternoon or evening, pause and count: How many decisions have you already made today? If the answer is "a lot" or "I've been in back-to-back meetings," postpone the decision to your peak window tomorrow. Write it down so you don't lose it.
A significant decision lands late in the day, after hours of meetings, or when you feel mentally flat.
The decision genuinely cannot wait and you've confirmed this with a false deadline check.
Why it works
Decision quality degrades measurably across the day as cognitive resources deplete. The dangerous part is that your confidence doesn't drop at the same rate — you feel certain but you're impaired.
Judges grant parole at 65% in morning sessions and near 0% by late afternoon — reverting to the safe default as their decision capacity drains. Your quality of judgment declines across the day as choices, meetings, and micro-decisions accumulate. Whether the mechanism is resource depletion or accumulated fatigue, the pattern is consistent across real-world data. The dangerous part is asymmetry — your confidence doesn’t flag at the same rate as your judgment. You feel just as certain about a 7pm decision as a 9am one, but you’re measurably more impaired. Schedule high-stakes decisions for high-energy hours. Treat late-day conviction with suspicion.
