    Their words

    uh one is factfulness by the late Hans Rosling. Uh this is a book that just brings global health data to to to the world.

Elie HassenfeldChanged their mind
  • Their words, before

    I put less weight on explicit cost-effectiveness analysis. Conceptually, my goal is to maximize the impact of my charitable contribution, but I put less weight on the explicit cost-effectiveness models we create than others.

    Their words now

    I remain ambivalent about putting so much weight on cost-effectiveness estimates because they are subject to numerous debatable assumptions, but I’ve changed my mind based on work we did over the past few months.

Beliefs

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.
