    Paradox & Proof Entry #0162

    The reason a queue can move faster with fewer servers

    Adding a server lets customers choose a line. Choosing a line means choosing wrong, and the time spent switching exceeds the time saved by the extra server.

    Adept
    The hidden part #0162

    Three queues offer choice. One queue offers coordination. The coordination saves the time the choice was wasting.

    Persuasion Systems Entry #0251

    Why a small favour precedes a large request

    The first yes is small enough to cost nothing. The second is large enough to matter. The bridge between them is the need to stay consistent with the self.

    Novice
    The hidden part #0251

    Consistency with the self is the lever. The first favour does not persuade; it creates the identity that the second favour appeals to.

    Statistical Illusions Entry #0428

    Why a ninety-nine per cent accurate test is usually wrong

    A test that is right ninety-nine times in a hundred can still be wrong about most of the cases it flags, and simple arithmetic shows why.

    Novice
    The hidden part #0428

    Accuracy is a property of the test. Whether an alert is right also depends on how rare the thing is.

    Hidden Words Entry #0001

    Why “clue” used to be a ball of yarn

    Before it meant evidence, a clue was a physical thread — the one Theseus unwound through the labyrinth so he could find the way back out.

    Master
    The hidden part #0001

    Following a clue is not a metaphor for detection. It is a description of walking backwards along string.

    Paradox & Proof Entry #0161

    Why unanimous agreement lowers confidence in a verdict

    Perfect consensus in a large group implies a shared error. The very agreement that looks like certainty is evidence against it.

    Novice
    The hidden part #0161

    Perfect agreement among many is not strong evidence. It is evidence of a shared input, which may be the truth or may be the error.

    Paradox & Proof Entry #0160

    The reason a prediction can cause its own failure

    The forecast changed the system it was forecasting. The prediction was accurate about the world before it was announced, and inaccurate about the world after.

    Master
    The hidden part #0160

    A prediction that enters the system it describes is no longer a prediction. It is a participant, and participants change outcomes.

    Paradox & Proof Entry #0159

    Why the safest route is the one nobody takes

    Safety attracts traffic. Traffic erodes safety. The route that was safest when empty is the most dangerous when full, and the dangerous one is now empty.

    Adept
    The hidden part #0159

    Safety attracts use. Use erodes safety. The safest route is the one whose conditions deterred you from choosing it.

    Attention & Memory Entry #0181

    The reason the first and last items survive the list

    Recall of a list is reliably U-shaped. The ends are protected by two different mechanisms, and the middle is protected by neither.

    Adept
    The hidden part #0181

    Two mechanisms guard two ends. Primacy survives a delay and recency does not, which is how they are told apart.

    Incentive Design Entry #0380

    Why commission changes advice more than dishonesty

    Advisers paid by outcome rarely lie. They notice different options, so the incentive does its work through attention rather than through deceit.

    Master
    The hidden part #0380

    An incentive does not need to corrupt anyone. It only needs to change which option comes to mind first.

    Negotiation Frames Entry #0337

    The reason a package beats a sequence of single issues

    Discussing issues one at a time turns every item into a win or a loss. Bundling them allows trades in which both sides record a gain.

    Adept
    The hidden part #0337

    A sequence turns every issue into a contest. A package turns every issue into a currency. The second produces deals the first cannot reach.
