New article in Journal of Communication looking at changes to trust in news across 46 countries in the last 10 years.

Trust in news declined in just over half of countries.

It decreased more in countries where TV news use has declined, and/or where social media news use has grown.

A thread:
The link between changing news use and trust: longitudinal analysis of 46 countries
Abstract . Changing levels of public trust in the news are of deep concern to both researchers and practitioners. We use data from 2015 to 2023 in 46 count

First order of magnitude given low median investment on health, education, infrastructure, etc it doesn't seem like population is a global constraint.

Of course, Ethnocentric limits on migration *do* conjure local problems, but those have direct solutions. 1/

Machines don’t rebel, they redistribute.
Minniti, @klausprettner.bsky.social‬ & @franceventurini.bsky.social show in EER that as #AI grows across #Europe, labour’s share of #income declines, especially among the educated.
This is a precise and profit-minded revolution.

We show how the deployment of #AI affects the #wages of low-skill workers and high-skill workers. According to the results, AI may reduce wage #inequality.

Many thanks to the editor Samuel Vigne and the anonymous referee for many helpful suggestions that helped to improve the paper.

Tariffs get all the attention, but ask economists what they're really worried about and many will point to the Trump administration's cuts to federal support for the sciences, including canceling grants and revoking student visas.

"We can heal the sick and save children’s lives, all inexpensively... We properly honor a firefighter who saves a single child, but three cheers for us as taxpayers for rescuing millions of children around the world from AIDS, starvation and disease.

That is, until January."

Opinion | Musk Said No One Has Died Since Aid Was Cut. That Isn’t True. (Gift Article)
A journey through the front lines of global poverty shows that when the world’s richest men slash aid for the world’s poorest children, the result is sickness, starvation and death.

I will never forget the photo of Zelenskyy’s face after he saw Russia’s war crimes in Bucha in 2022. He seemed to age years in an afternoon. Watching him constantly cross the world asking for aid that should have been thrown at him is one of the deepest shames of our age.

An attempt by the popular video-sharing app TikTok to assuage EU lawmakers' concerns backfired yesterday, as company executives faced hostile politicians questioning its role in ultranationalist Călin Georgescu's win in the recent first-round of Romania's presidential election.

Few people even know about this; when people are asked in surveys how child mortality has changed the majority says it has stagnated or increased.

If you consider that many don't know about humanity's biggest achievement, then it's not surprising that many are so pessimistic about our future.

Here’s a crazy fact for you: Spain and Germany have now seen basically the exact same amount of economic growth post-2008. Would have been unthinkable to people during most of the 2010s. Spain has seen ~10 percentage points more cumulative growth since 2017.
