False Scarcity

No operable specimen exists yet; the illustration is editorial. Before applying this to a product, verify whether the stock badge and activity counter are actually bound to real inventory and concurrency data, whether the numbers are consistent across different people and times, whether the number is truly removed (not replaced with an estimate) when it cannot be computed, and the specific rules on false scarcity claims in the relevant jurisdiction.

  "harm": "Fabricated stock or activity numbers shrink the room for careful comparison, inducing purchases people would not otherwise make, and erode trust in the site's other information once the numbers are found to be fake",
  "repair": "Show a number only when it can be reliably computed from real inventory or concurrency data; when it cannot, remove the number and state the real limitation in words instead."

  "definition": "Show people signals of limited supply or strong demand that do not actually exist or cannot be verified (a fabricated \"only # left\" stock badge, a \"# people are viewing/buying this\" counter), creating a pressured sense of scarcity that pushes them into a purchase without proper evaluation.",
  "boundary": "Different from false urgency: the mechanism here is fabricating a quantity or demand signal, not a time deadline; the two often appear together but should be logged separately. A stock or activity number that genuinely traces back to a real inventory system or real concurrent-user data is not this anti-pattern. The test is whether the number is computed from real underlying data, not whether it sounds alarming.",
  "signature": [
    "The stock or \"only # left\" badge cannot be traced to a real inventory system, and the number changes inconsistently on reload or across devices",
    "The \"# people are viewing/buying this\" counter is wildly out of proportion to the site's actual traffic or order volume, or shows the same number to every visitor",

  "tradeoff": "Repair by keeping only verifiable numbers: a stock badge must reflect a value computed from a real inventory system, and an activity counter must reflect real concurrent visits or purchases. When a number cannot be computed reliably, show no number at all — instead state plainly what \"limited\" means (a scarce source material, a limited production run, seasonal supply) rather than presenting an isolated, possibly fabricated figure.",
