1. Concept gate

Reader's real question:

  • Why do I keep the route, the launch, or the landing after the facts that justified it have changed?

Why this belongs in the catalog:

  • Completion bias is the itch to close an open unit. Sunk cost is money or time already spent. Status quo is preferring the current option. This page is the active course that stays in force because rebuilding it costs more effort than pressing on.

Bug claim in one sentence:

The bug is Plan Continuation Bias, where an original course of action makes later contrary cues harder to treat as a reason to choose again.

What this bug is not:

  • Not a claim that plans should be abandoned at every change.
  • Not a claim that a bad outcome proves the continuation was an error. The source paper warns about hindsight.

Nearby bugs to check:

Nearby bugDifference
Completion BiasUnfinished unit. Plan continuation is a course after conditions change.
Sunk Cost FallacyPast spend. This can run when little has been spent.
Status Quo BiasCurrent possession or default. This is an active mission.
Vertical Line FailureA failed step sequence. This is the destination or the plan.
Planning FallacyThe estimate was too small from the start.

Concept gate: yes

3. Article plan

Explained boundary: Continuing after an update can be correct. The bug is contrary cues explained away, with the alternative never actually built.

Examples planned: launch Friday, forecast, client moved the goal, turning around wastes the morning, meeting still on the calendar, divert looks like panic, flown this approach before.

Scenarios: drive, launch, hike, clinic pathway.

Prevention: name the divert cue in advance; choose as if starting now; cost of staying beside cost of changing; near the end, be stricter.

Reframes: the drive, the launch, almost there.
