    Price Psychology Entry #0359

    Why the second unit is where the margin lives

    The first unit is priced to attract. The second is priced to profit. The buyer who came for the bargain discovers the margin at the refill.

    Adept
    The hidden part #0359

    The first unit is an invitation. The second is the business. The margin lives where the comparison ended.

    Narrative Structure Entry #0530

    Why an unresolved ending is remembered longer

    An interrupted task stays in mind longer than a completed one, which is why unresolved endings outlive the stories that finish tidily.

    Master
    The hidden part #0530

    Completion releases attention. Anything left open keeps a claim on it.

    Platform Mechanics Entry #0287

    The reason a platform’s rules change after you build on them

    The rules were generous when they needed builders. Once the builders are invested, the rules can be revised, because the cost of leaving exceeds the cost of complying.

    Adept
    The hidden part #0287

    Generous terms attract investment. Investment creates dependency. Dependency permits revision. The sequence is not accidental.

    Narrative Structure Entry #0532

    Why data needs a protagonist to travel

    Aggregate evidence persuades less than a single named case, and adding the aggregate to the case can reduce the response rather than strengthen it.

    Novice
    The hidden part #0532

    A number describes a population. A person creates an obligation, and only the second one moves people.

  • Why every price ends in 99
    Hidden Numbers Entry #0005

    Why every price ends in 99

    $9.99 is not one cent cheaper than $10. It is one whole digit cheaper — and the digit is the part you actually read.

    Novice
    The hidden part #0005

    You read prices left to right and stop early. The 99 arrives after you have already decided.

    Platform Mechanics Entry #0286

    Why moderation is a pricing problem, not a values problem

    At scale, every piece of content must be reviewed at a cost that approaches zero. The cost determines what gets caught, and the values follow the budget.

    Novice
    The hidden part #0286

    Values are free to declare. Moderation costs money per decision. At scale, the budget determines what the values actually mean.

    Platform Mechanics Entry #0285

    The reason switching costs are designed, not incidental

    Importing data is easy and exporting it is hard. The asymmetry is not an engineering oversight. It is the business model, and the difficulty is the product.

    Master
    The hidden part #0285

    The path in is lit because it serves the platform. The path out is dark because it serves the user. The two interests diverge, and the architecture follows the interest it was built to serve.

  • Benford’s Law: why 1 leads the ledger
    Hidden Numbers Entry #0004

    Benford’s Law: why 1 leads the ledger

    In real-world data, about 30% of numbers start with the digit 1 and only 4.6% start with 9. Fraud investigators use that gap as a lie detector.

    Master
    The hidden part #0004

    Genuine numbers are unevenly distributed. Invented numbers are suspiciously even.

    Platform Mechanics Entry #0284

    Why network effects make second place worthless

    The value of the first network rises with each user. The value of the second rises too, but the gap between them widens rather than closes.

    Adept
    The hidden part #0284

    The first network large enough owns the people. The second can copy every feature except the one that matters.

    Platform Mechanics Entry #0282

    Why recommendation systems narrow taste while widening catalogue

    The library grows every month and the same titles keep arriving at the top. Availability and discoverability are separate quantities that can move apart.

    Novice
    The hidden part #0282

    Catalogue size and reachable set are different numbers. Recommendation confidence is built from attention already spent.

    Habit Loops Entry #0303

    Why changing a route changes a routine

    A habit feels like a decision stored in the person, but it is actually stored in the environment. Move the person and the habit loses its cue.

    Novice
    The hidden part #0303

    Habits are stored with their surroundings. Change the surroundings and the habit has to be rebuilt from scratch — or it simply does not fire.

    Persuasion Systems Entry #0262

    The reason storytelling disarms counter-argument

    An argument invites a counter-argument. A story invites the listener inside, and the interior is not a place from which counter-arguments are launched.

    Adept
    The hidden part #0262

    An argument is evaluated. A story is entered. Inside the story, the machinery that produces objections is occupied elsewhere.
