    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.

    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.
