Understanding convictions, your own included

Letting nothing show reduces what is seen, not what is felt. A series of experiments conducted from 1998 onwards measured what this operation costs.

Say everything or say nothing, leave space or close the distance: the recommendations cancel each other out. This is not a flaw in the field, it is its nature.

Following the same thousands of children for twenty years is expensive and takes twenty years. It is nonetheless the only design that separates what comes before from what comes after.

France publishes an unemployment rate and a number of registrants that do not coincide. That is not a contradiction, they are two definitions.

The question asked determines the figure obtained. Two similar wordings produce networks of very different sizes, which has already derailed an entire public debate.

In a growing share of jobs, producing an affective state is part of the task. A sociologist named this in 1983, and research has measured since then what it costs.

A specific set of measures has been built up over fifteen years. Its fastest remedies are also the least known to those they concern.

In France the obligation starts at three, and has done since 2019. Elsewhere in Europe it starts at four, five, six or seven, and those gaps do not mean what one assumes.

Comparing a qualification with a job, a job with one's parents' or a job with one's expectations does not measure the same thing nor the same people.

A 1950 study of student housing showed that distance in metres predicted friendships. The result has been confirmed and refined since.

The abbreviation has circulated since 1995 and suggests the existence of a measure comparable to the intelligence quotient. No serious instrument produces anything of the kind.

Dates, rituals and conventional gestures are readily mocked. Yet they fulfil a precise function, and their absence is noticed more than their presence.

Finding oneself in the middle of a scale does not have a single meaning. Three very different situations produce the same point, and it is worth knowing which is yours.

Few subjects set such sharply drawn camps against each other on such thin data. Here is what the published trials actually measure, and what they stay silent on.

The figure is everywhere in management training. It appears in none of his writings, and the theory it illustrates has never been validated.
