Re-Deciding Pays the Full Cost of Deciding

# Re-Deciding Pays the Full Cost of Deciding ## Claim Revisiting a settled decision costs what the original decision cost, so the compounding drain is not the number of choices you face but the number of times you face the same one.  ## Evidence **Source**: [[3. Resources/Readwise/Articles/Decision Fatigue Why You Feel Exhausted Without Having “Done” Anything Physically]] — FacileThings, on decision fatigue and GTD The framing worth keeping is the asymmetry between deciding and re-deciding. Deciding once produces a durable result. Re-deciding produces the same result at the same price — the options have to be reloaded, the tradeoffs re-weighed, the choice re-made — and the second payment buys nothing the first did not already buy. This explains why a day with few genuine decisions can still end in exhaustion. An open loop is not one decision pending; it is one decision paid for repeatedly, every time attention lands on it. The corresponding GTD moves all attack recurrence rather than volume. *Planning without completing* closes the loop by converting "what should I do about this?" into a decided next action, so the item stops re-presenting itself as an open question. Routines and defaults remove whole classes of choice from the daily surface. "Decide once" is the general form. A note on the evidence, because the popular version of this is shakier than it reads. The 2011 PNAS parole-judge study — favourable rulings falling toward zero across a session and resetting after a break — is the usual illustration, and it has been substantially critiqued on case-ordering grounds. Ego depletion, the mechanism originally offered, largely failed replication in 2016. The claim here does not depend on either: it needs only that reconsideration costs roughly what consideration cost, which is a claim about redundancy rather than about a depleting resource. ## Scope & conditions - **Holds** for decisions that are genuinely settled and genuinely re-opened — the cost is in reloading context, not in the choice being hard. - **Breaks** where the world has changed enough that the earlier decision no longer applies. Then it is a new decision wearing an old one's clothes, and re-deciding is correct. - **Weakens** where the decision is trivial enough to re-make from cache, which is precisely what defaults and routines manufacture. - **Sharpens** with the number of people involved — a group re-deciding pays the cost once per person, plus the cost of re-synchronizing. - **Does not require** ego depletion to be true. The mechanism is redundant work, not a finite reserve. ## Links - [[3.

This is that note's cost side, stated in attention rather than in code. - [[3.

Every recurring decision is a candidate for a default, a routine, or a written policy. - It is the strongest practical argument for policy files — a documented convention converts a per-instance decision into a one-time one, and its value scales with how often the situation recurs rather than with how hard the choice was. - Capture systems earn their cost here specifically. Writing an item down is worth it not because the item might be forgotten but because it stops being re-evaluated on every pass. - Be skeptical of the parole-judge illustration when it appears in productivity writing. The underlying advice survives the critique; the dramatic version of the evidence does not. ## Open Questions - Is the cost of re-deciding actually equal to deciding, or discounted by partial recall? The practical advice is unchanged either way, but the size of the effect is not known. - How does re-deciding interact with genuinely improved judgment — some revisiting produces better outcomes, and this frames all of it as waste. - Do written defaults reduce the cost, or do they relocate it into deciding whether the default still applies? ## Source - [[3.
