Attention & Memory
Entry #0196
Rereading feels like learning and mostly is not. The method that feels least productive is the one that leaves the most behind.
The hidden part
#0196
Fluency is a sensation, not a measurement. The method that feels like it is failing is frequently the one doing the work.
Reveal the hidden insight of Why testing yourself beats rereading

Attention & Memory
Entry #0185
The intention survived the corridor and died in the doorway. Not because memory failed, but because the doorway is doing something specific.
The hidden part
#0185
The doorway is not where the intention was forgotten. It is where the mind decided the previous scene had ended.
Reveal the hidden insight of The reason you forget why you walked into the room

Cognitive Bias
Entry #0107
Both sides argue for an hour and land near the figure one of them said in the first minute. The argument was real. It was also decorative.
The hidden part
#0107
Anchoring is not the failure to move. It is that the whole conversation happened inside a region somebody else chose before it began.
Reveal the hidden insight of Why the first number in a negotiation outlives the argument

Statistical Illusions
Entry #0441
Dividing by population removes size from a comparison. Since size drives most totals, the ranking that survives is often the opposite of the original.
The hidden part
#0441
A total measures magnitude and a rate measures intensity. Which one is published decides most of the ranking.
Reveal the hidden insight of The reason per capita reverses many rankings

Statistical Illusions
Entry #0440
A measure requires a definition, and once the measure is consequential the definition becomes something to be managed rather than merely applied.
The hidden part
#0440
A number is a definition applied to the world. Make the number consequential and the definition becomes the thing under negotiation.
Reveal the hidden insight of Why counting something changes what gets counted

Statistical Illusions
Entry #0439
A single number implies a precision the forecast does not have. The width of the interval is the part that says how much the forecast actually knows.
The hidden part
#0439
Two forecasts with the same midpoint and different widths are different forecasts. Only one of those numbers usually survives.
Reveal the hidden insight of The reason a forecast range matters more than its midpoint

Statistical Illusions
Entry #0438
A mean is pulled by every extreme value in the set. A median is not, so for skewed quantities it describes the ordinary case far more closely.
The hidden part
#0438
A mean answers a question about the total. For a skewed quantity, only the median approximates the ordinary case.
Reveal the hidden insight of Why the median rent tells you more than the average

Social Proof
Entry #0218
A single account from someone you know is a worse sample and a better source. It carries accountability and detail that an aggregate statistic cannot.
The hidden part
#0218
A friend is a poor sample and an accountable one. A study is a good sample that cannot be questioned.
Reveal the hidden insight of The reason a friend’s recommendation outranks a study

Social Proof
Entry #0216
Copying a successful practice requires no understanding of why it works, which is why practices travel through populations faster than explanations do.
The hidden part
#0216
A practice can be copied without being understood. Explanations travel at the speed of investigation, practices at the speed of observation.
Reveal the hidden insight of The reason imitation spreads faster than instruction

Social Proof
Entry #0215
Writing a review costs effort that only a strong reaction repays. The distribution of published opinion is therefore not the distribution of opinion.
The hidden part
#0215
Reviews sample the strength of reaction, not the population. Volume increases precision about the wrong quantity.
Reveal the hidden insight of Why the loudest reviewer is rarely the typical customer

Social Proof
Entry #0214
A rule can be maintained entirely by enforcement. When each person doubts it privately and polices it publicly, nobody encounters evidence that anyone doubts.
The hidden part
#0214
A norm needs no believers, only enforcers. Zealous enforcement by the unconvinced is what keeps it looking supported.
Reveal the hidden insight of The reason a norm survives after everyone stops believing it

Scarcity & Queues
Entry #0467
A lottery gives everyone the same chance and no way to express how much they need the thing. A price does the reverse, and each ignores what the other records.
The hidden part
#0467
Every allocation rule declares which claims count. A lottery says all equally; a price says according to capacity to pay.
Reveal the hidden insight of Why a raffle allocates differently than a price
