    Statistical Illusions Entry #0437

    The reason a study that replicates is worth two that do not

    A single study is a claim. A replication is a test of that claim. Two unreplicated studies are two untested claims, not twice the evidence.

    Adept
    The hidden part #0437

    Novelty fills journals. Replication fills knowledge. The incentive structure rewards the wrong one.

    Decision Architecture Entry #0131

    The reason you decide differently before and after lunch

    Across a long session of similar decisions, the safe default is chosen more often as the session goes on. Why that happens is still argued about.

    Adept
    The hidden part #0131

    Position in the queue is an unrecorded input. Effort-saving accumulates across a session while each case still gets a full justification.

    Habit Loops Entry #0321

    Why sleep debt undoes behavioural change

    Deliberate control is expensive to run. Accumulated wakefulness degrades exactly the functions a new routine depends on, while leaving old routines intact.

    Novice
    The hidden part #0321

    A new routine runs on expensive machinery and the old one does not. Degrade the machinery and the old one returns unopposed.

    Framing Effects Entry #0522

    The reason a metaphor decides a policy debate

    A metaphor imports the logic of its source. Once crime is a virus, the conversation is about containment, and containment was never voted for.

    Adept
    The hidden part #0522

    A metaphor is not decoration on an argument. It is the machinery the argument runs on, and it arrives with its conclusions pre-installed.

    Cognitive Bias Entry #0122

    The reason a small loss hurts more than a larger gain pleases

    Outcomes are not evaluated against zero. They are evaluated against a reference point, and the slope below it is steeper than the slope above it.

    Adept
    The hidden part #0122

    Nothing is judged against zero. It is judged against wherever you last stood, and the ground below that point is steeper than the ground above.

    Attention & Memory Entry #0199

    The reason an unfinished sentence holds attention longest

    An interrupted task stays active in a way a completed one does not. The pull is not curiosity about the answer but an accounting entry left open.

    Master
    The hidden part #0199

    What holds you is not the missing answer. It is an open entry, and only completion closes it, which is why finishing something bad still feels necessary.

    Statistical Illusions Entry #1127

    Why the winner’s curse inflates first results

    Winner's curse makes the first significant result look stronger than it really is, because extreme estimates are the ones that win.

    Master
    The hidden part #1127

    When many noisy estimates compete, the winner is often the most exaggerated one.
