When Is It OK to Decide for Other People? Said 17 Sept 2026
Paternalism feels more acceptable for big, hard-to-reverse decisions that resist learning and carry deep information gaps
Put these four together — a big decision, hard to reverse, resistant to learning, with deep information asymmetry — and under those conditions I feel much more comfortable saying: let’s not make everyone figure this out alone.

Small, reversible, learnable decisions between equally informed sides should be left to people, with no paternalism
Small decision? Reversible? Easy to learn from? Both sides equally informed? Then leave people alone — that is exactly the territory where freedom to make our own mistakes is how we learn, and where paternalism has no business.

Why Louisiana’s Ten Commandments law is a broken moral compass Said 13 Jul 2024

Society needs consequences, but they should be proportionate and leave room for rehabilitation, reconciliation or recompense
To be sure, society can’t function without rules, boundaries, and consequences, but they should be proportionate. We must change the way we judge one another, to allow room for rehabilitation, reconciliation, or recompense.

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.
