  1. The Decoy Effect — How an Irrelevant Option Changes Your Choice
    The decoy effect, documented by Huber, Payne and Puto (1982), is the finding that adding a third option that is clearly inferior to one of two existing options (but not the other) reliably shifts preference toward the option it is "dominated by." It shows that preferences between options are not fixed: they are constructed in context, and the comparison set shapes the outcome.
  2. Evaluate each option against your criteria before comparing options to each other
    Score options independently first — so the comparison set can’t retroactively redefine what good looks like.

  3. Simplify complex choices to prevent comparison fatigue from enabling decoys
    Too many options increase susceptibility to decoys — constrain the comparison set before evaluating.

  4. Use the decoy structure to guide others toward better options
    If you’re structuring choices for a team or organization, include a dominated option to help people recognize and choose the best option.

  5. Recognize decoys in political and narrative framing
    In debates and narratives, an extreme position is often introduced to make a moderate position seem reasonable — identify this before updating.

  6. Check whether a third option is changing your view of the original two
    If a new option makes you change your preference between existing options, ask whether the new option should have that power.

  7. Identify the decoy tier in pricing and subscription structures
    When one pricing option seems designed only to make another look good, it is probably a decoy — don’t let it anchor your choice.

  8. Identify price anchors before they calibrate your sense of value
    The first price you see for a category sets the anchor — recognize it before it defines what seems cheap or expensive.

  9. Recognize when contrast is being used on you
    Awareness of the contrast principle is the antidote — evaluate options against an independent standard, not the presented sequence.

  10. The Spotlight Effect: Why You Think Everyone Is Watching
    The spotlight effect is the well-documented tendency to overestimate how much other people notice our appearance, mistakes, and actions — because we are the center of our own attention, we assume we are the center of theirs. Reducing this bias requires deliberately updating the estimate of how distracted, self-occupied, and inattentive others actually are.
