    Decision Architecture Entry #0140

    Why the checkbox already ticked is the business model

    A pre-ticked box does not persuade anyone. It converts consent from something obtained into something not withdrawn, and inattention supplies the difference.

    Master
    The hidden part #0140

    The default is not a suggestion. It is the answer given by everyone who does not answer.

    The reason a countdown changes what counts as enough information

    Under time pressure the decision rule shifts. The threshold for sufficient evidence drops, and the drop goes unnoticed because certainty does not drop with it.

    Adept
    The hidden part #0139

    Time pressure does not make people less certain on less evidence. It lowers the evidence needed to feel certain.

    Decision Architecture Entry #0137

    The reason you accept a worse deal when you chose the shortlist

    Selecting the options feels like authorship of the outcome. Ownership of the shortlist transfers to the choice made from it, whatever the shortlist excluded.

    Adept
    The hidden part #0137

    Whoever writes the shortlist makes the decision. Whoever picks from it gets the feeling of having made it.

    Why the wording of a default reveals the intended answer

    A pre-selected option is not read as an arbitrary starting point. It is read as advice from whoever built the form, and usually that reading is correct.

    Adept
    The hidden part #0150

    A pre-ticked box is advice with the author removed. Reading it as a recommendation is not a mistake, it is accurate.

    Decision Architecture Entry #0149

    The reason a plan survives contact with nobody

    A plan announced publicly acquires a defender before it acquires evidence. Announcing it also delivers part of the satisfaction that completing it was meant to supply.

    Master
    The hidden part #0149

    A published plan gains a defender before it gains evidence, and the announcement already paid out part of the reward.

    Decision Architecture Entry #0148

    Why you spend more when the currency is unfamiliar

    The count of digits is processed faster than the exchange rate. A larger nominal figure feels expensive and a smaller one feels cheap, whatever it converts to.

    Adept
    The hidden part #0148

    Digit count is read before exchange rate. The conversion then corrects an impression that has already been filed.

    Decision Architecture Entry #0147

    The reason opting in twice feels safer than once

    A second confirmation adds no information about the decision. It adds a record that the decision was taken carefully, which is what the process is really producing.

    Adept
    The hidden part #0147

    The second confirmation certifies nothing about the decision. It certifies that a decision was taken, to someone who will ask later.

    Why the last question of an interview decides the first impression

    A judgement formed at the end is not appended to what came before. It reorganises the whole hour into a story with that ending as its conclusion.

    Novice
    The hidden part #0146

    The ending does not get added to the hour. It rewrites the hour into a story that was heading there all along.

    The reason a bundled price stops comparison

    A single figure covering several items cannot be checked line by line. Comparison requires prices for the parts, and the bundle exists to withhold them.

    Master
    The hidden part #0145

    A bundle discloses the total honestly and withholds the only prices you could have checked. Nothing is hidden at the level you can see.

    Why a single reason persuades better than five

    Audiences do not total up arguments. They form an impression somewhere near the average, so a weak addition drags a strong case downwards.

    Adept
    The hidden part #0144

    You add and they average. Your fourth-best argument is not a contribution, it is a subtraction from the mean.

    Decision Architecture Entry #0143

    The reason you prefer the option you can explain

    Choices have to be defensible to somebody, often yourself. An option that comes with a sayable reason outranks a better one that does not.

    Novice
    The hidden part #0143

    Options do not compete on merit alone. They compete on whether they can hand you a sentence, and unsayable advantages lose.

    Decision Architecture Entry #0141

    The reason two-minute delays kill more purchases than price

    A small procedural cost can outweigh a large financial one, because the delay gives the decision time to be reopened and the money does not.

    Adept
    The hidden part #0141

    A delay is not priced in time. It is priced in the chance that the decision reopens, and reopened decisions rarely close the same way.
