What they believe
-
Confidence in a belief reflects the coherence of the story the mind built, not the quality of the evidence
The confidence that people have in their beliefs is not a measure of the quality of evidence, it is not a judgment of the quality of the evidence but it is a judgment of the coherence of the story that the mind has managed to construct.

Predictions should be less extreme than the information they rest on, an idea that is deeply counterintuitive
As I understood clearly only when I taught statistics some years later, the idea that predictions should be less extreme than the information on which they are based is deeply counterintuitive.

Subjective confidence can feel the same for intuitions from expertise and for intuitions from substitution
But the subjective sense of confidence can be the same for intuition that arrives from expertise, and for intuitions that arise from heuristics, that arrives from substitution, and asking a different question.

Loss aversion was the most useful contribution of the prospect theory work to the study of decision making
The concept of loss aversion was, I believe, our most useful contribution to the study of decision making.

Social science disciplines use ritual tests of competence that screen work by form rather than substance
Every discipline of social science, I believe, has some ritual tests of competence, which must be passed before a piece of work is considered worthy of attention. Such tests are necessary to prevent information overload, and they are also important aspects of the tribal life of the disciplines.

Which scientific writing gains lasting fame is decided by a strange and rather arbitrary process
It is a strange and rather arbitrary process that selects some pieces of scientific writing for relatively enduring fame while committing most of what is published to almost immediate oblivion.

Critique-and-reply debates in the social sciences are absurdly adversarial; hardly anyone admits an error
Both as a participant and as a reader I have been appalled by the absurdly adversarial nature of these exchanges, in which hardly anyone ever admits an error or acknowledges learning anything from the other.

People who make a difference do not die alone. Something dies in everyone who was affected by them.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.
About the English under a post
Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
