High-income countries often spend more than 150-times as much on the education of each child than poor countries.
It is important for poor countries to achieve growth — but even with little resources poor countries have ways to improve their education.

Saloni has been sharing great research on our internal Slack here in the Our World in Data team.
And to be honest, much of what I share on Twitter comes from her – you might as well get it directly from Saloni.

A new @Kurz_Gesagt video is out – on how very, very big the future could be.

@MaxCRoser I found this @metaculus question from 2016 assigning a 40% chance of a major naturally occuring pandemic before 2026
metaculus.com/questions/247/…
Retweeted by Max Roser Does someone know whether there were forecasts/predictions about the risk of a pandemic before COVID happened on sites like metaculus or the good judgement project?
I'm interested what these forecaster communities expected.
Per capita CO₂ emissions changed massively within countries (in some countries they increased; in others they halved).
But globally, CO₂ per capita changed very little.
For the last 50 years they were never below 4 tonnes and never above 5 tonnes per person.
When will the first general AI system be devised, tested, and publicly known of?
Previously the Metaculus forecaster community’s median answer was in the 2050s.
In recent months they updated their views. Now the median prediction is the year 2039.

There is a good chance that artificial general intelligence will be developed *within our lifetimes*.
Given how much is at stake it is incomprehensible that we are not talking about this way more.

Nothing about a graph makes Twitter commenters more angry than when someone exaggerates a trend by manipulating the y axis.
But they can finally let their rage drain away, This paper shows that misleading graphs don’t actually mislead people in real life. journals.plos.org/plosone/articl…

Retweeted by Max Roser Cam has been a pillar of @OurWorldInData's work on COVID for the last two years. Much of the data collection on testing and vaccinations was done by him.

Retweeted by Max Roser The Shadow Peace is a short film on the history of war and the risk of nuclear conflict.
It’s a kind of 'data visualization documentary', a new medium that the film’s creator – @neilhalloran – seems to single-handedly develop.

"Problems are solvable. Given enough time we can end the horrors of today. Poverty is not inevitable. Diseases that are incurable today might be curable in just a few generations."

Retweeted by Max Roser The work is hard, not impossible: "Even in the most challenging places – extreme poverty, very low education of parents, almost no infrastructure (no internet, no electricity, no roads) – it is possible to teach primary school children to read fluently and do basic math well" twitter.com/MaxCRoser/stat…
Retweeted by Max Roser An overwhelming majority of public sector officials agree that there is a learning crisis. But they don’t know the scale of this crisis. They overestimate the share of students in their country that CAN read by age 10. See paper by @leecrawfurd et. al

Retweeted by Max Roser Over the last few decades the world has made great progress toward eradicating polio.
But in the last few years we have been set back.
To get back on track, we need more screening and testing for polio.

Retweeted by Max Roser Good post by @Noahpinion. Even though I'm a big fan of Oxfam, I think they'd be even more effective if they take this criticism to heart. Poverty, inequality, tax evasion & tax avoidance are bad enough as they are, no need for dodgy stats. noahpinion.substack.com/p/oxfam-serves…
Retweeted by Max Roser US income inequality drops significantly in 2020 as social transfers increase incomes of the poorer groups and covid lockdowns etc. reduce real incomes of the rich.

Retweeted by Max Roser Thread on our survey on "A New Era in the Economics of Fertility."
Why a new era? Because everything has changed!
- The empirical regularities of fertility choice have reverted.
- The mechanisms emphasized by earlier research have lost relevance.

Retweeted by Max Roser The number of confirmed monkeypox cases in non-endemic countries increased steadily for some time.

I very much enjoyed working with the folks at @BBCMoreOrLess to bring Weingberg's differential rule to the airwaves & fibre. Listen at 14minutes in on bbc.co.uk/programmes/m00… for more about the odds of identical triplets. Are they really 1:200 million?
Retweeted by Max Roser In many schools children learn very little.
This is a problem in rich countries. By the end of primary school about 9% in high-income countries cannot read with comprehension.
But it is a much larger problem in poorer countries.

A very nice study by @KaitlinRaimi @KimWolske and others finding that contrary to many people's concerns, learning about carbon dioxide removal does not reduce people's support for reducing greenhouse gas emissions. It also has useful results for improving public communication. twitter.com/KaitlinRaimi/s…

Here's a long navel-gazing thread with my reactions:
Retweeted by Max Roser One of the insights from international data on test scores in mathematics:
students with the same household income tend to reach much better educational outcomes if they live in a richer country.

Research suggests that many children – especially in the world’s poorest countries – learn only very little in school.
What can we do to improve this?
