The participants knew Gandhi was neither nine nor 140 when he died. Their later estimates still moved towards whichever absurd number had appeared first. Rejecting the claim did not remove the scale it supplied. The ridiculous figure never had to win an argument. It only had to become available before a plausible estimate was formed.

Commercial anchors exploit that residue. A list price interprets the discount. The first salary range narrows negotiation. A speculative delivery estimate becomes strangely authoritative after the difficult work is discovered. Awareness offers limited protection because adjustment still begins from the number currently available. Independent estimates, comparable cases and constituent costs create other starting points before charm or status chooses one. They also reveal when an anchor deserves to remain: last year’s actual cost, ordinary usage or a credible alternative can make an unfamiliar figure easier to judge. The issue is not that a number came first. It is whether anything stronger than arrival earned that privilege.

The ethical divide sits in the evidence. A fabricated recommended price manufactures value. An impossible schedule manufactures failure while pretending to inspire urgency. Both may influence the decision; influence is hardly a certificate of legitimacy. The first number acquires seniority simply by surviving the first conversation. Months later, people will discuss careful revisions around a figure nobody ever established. Each adjustment feels reasoned because the original absurdity has become too old to question. That is the anchoring effect wearing business casual.
