    Paradox & Proof Entry #0154

    The reason a fair coin produces unfair-looking runs

    In two hundred fair tosses a run of seven identical results is likely. People asked to fake the sequence almost never allow one, which is how fakes are detected.

    Adept
    The hidden part #0154

    Randomness clusters. The expected longest run in a fair sequence is far longer than intuition permits, so real data looks rigged.

    Cognitive Bias Entry #0109

    Why bad weather darkens a market forecast

    Sunshine and overcast skies have no informational content about equities, and yet market returns correlate weakly with local weather.

    Adept
    The hidden part #0109

    Mood enters the forecast as though it were data. The sky has no opinion about equities, but the forecaster does not separate the two.

    Paradox & Proof Entry #0156

    The reason improving every hospital can worsen the statistics

    Every department improved. The overall figure got worse. Both statements are true at once, and the reason is one of the most useful traps in data.

    Master
    The hidden part #0156

    A total is not a neutral summary of its parts. It is the result of a grouping decision, and that decision can point the conclusion in either direction.

    Attention & Memory Entry #0186

    Why reading on paper is remembered differently to screen

    Readers on paper locate a passage by where it sat on the page. Readers on screen scroll and the spatial anchor disappears.

    Novice
    The hidden part #0186

    Paper gives a passage a place. A screen gives it a position in a stream, which moves on.

    Attention & Memory Entry #0184

    Why background music helps one task and ruins another

    Music with lyrics impairs reading and leaves arithmetic untouched. The damage is channel-specific, not a general drain on attention.

    Adept
    The hidden part #0184

    Music competes only with tasks that use the same channel. Lyrics fight language; a beat does not.

    Attention & Memory Entry #0183

    The reason a familiar route feels shorter going home

    The outward journey takes longer than the return, though the distance is the same. What changed is what the traveller expected.

    Adept
    The hidden part #0183

    The road did not change. The forecast did. Duration is the gap between what happened and what was expected.

    Cognitive Bias Entry #0104

    The opinion you defend hardest is the one you understood least

    The loudest defence usually protects the thinnest reasoning. Volume compensates for a foundation the speaker has never actually inspected.

    Adept
    The hidden part #0104

    Confidence is not compressed knowledge. A thin model has fewer visible gaps than a detailed one, so it is easier to defend loudly.

    Attention & Memory Entry #0182

    Why sleep decides what yesterday meant

    A day deposits more than it can store. Sleep selects which portions are kept and which are discarded, and the selection is not random.

    Novice
    The hidden part #0182

    Sleep is not a gap in processing. It is when the day is edited into what will count as having happened.

    Cognitive Bias Entry #0101

    Why you remember the one bad review out of forty

    Thirty-nine people were satisfied. You are thinking about the fortieth. That is not a flaw in your attention; it is the oldest filing rule the mind has.

    Novice
    The hidden part #0101

    The complaint is not more truthful than the praise. It is only cheaper to remember, and the mind mistakes ease of recall for weight of evidence.

    Rhetoric & Omission Entry #0582

    Why an argument built on definitions is hard to answer

    The dispute appears to be about a policy and every exchange is about what a word covers. One side is arguing inside a definition it conceded.

    Novice
    The hidden part #0582

    Whoever supplies the definition supplies the criteria. Everything after that is administration.

    Naming & Sound Entry #0553

    Why a hard consonant suits a tool and a soft one a comfort

    The sound of a word carries meaning before the word is understood. A sharp k fits a blade; a soft l fits a pillow. The mapping is cross-cultural and pre-verbal.

    Novice
    The hidden part #0553

    Articulation maps onto qualities. The mouth does not only say the name; it performs a miniature version of the attribute the name will carry.

    Framing Effects Entry #0506

    The reason time framing changes charitable giving

    Two appeals for one cause. The one that asks about time before it asks about money collects more money, and the money request comes second.

    Adept
    The hidden part #0506

    The first unit named sets the terms of the whole request. Time invites meaning; money invites arithmetic.
