  "limitations": [
    "The 2026 paper is a replication of a specific deadline experiment and does not test every form of deadline, planning, precommitment, or time-management intervention.",
    "Failure to reproduce the classic effect lowers confidence in that specific evidence claim; it does not establish that deadlines have no effect in every task, population, incentive structure, or real-world setting.",
    "The publisher's retraction of the 2002 paper means Brali should not use that paper as positive evidence, but retraction alone is not evidence for the opposite universal claim.",
    "This decision is a provenance and evidence-boundary correction, not a complete systematic review of the broader deadline literature."
