The U.S. is the only place we surveyed where more adults describe the morality of others living in the country as bad than good.

Canada is on the opposiite end of the spectrum--they overwhelmingly see their neighbors as morally good

This figure shows the percentage of respondents in 35 countries across the International Social Survey Programme (ISSP) and the Integrated Values Survey (IVS) who rate “hard work” as more important than structural factors for getting ahead in life. Dark blue diamonds (IVS) and dark green circles (ISSP) represent survey year averages. Light blue and light green lines plot the trend in meritocratic beliefs across the five-year cohorts, on the basis of locally weighted least squares regressions on the cohort-country means (light blue diamonds [IVS] and light green circles [ISSP]). IVS data show whether respondents rate hard work (1) or luck and connections (0) as the more important factor for achieving a better life. ISSP data show the share of respondents who rate hard work as more important than “knowing the right people” and “coming from a wealthy family” for getting ahead in life.

The figure shows annualized change scores (subtracting the earliest from the latest value and standardizing by the number of years/cohorts). This figure is only included in the supplementary material.

How has the public belief in meritocracy changed over time? We address this question in our new Data Viz (@sociusjournal.bsky.social) by examining trends in popular beliefs across cohorts and periods in 35 countries, based on two datasets.

📌 Professional fact-checkers are a major source of Grok.

Karpf: "If you think Claude Code is a better social scientist than you, then you’re probably right. But that means, at some point, you stopped trying to answer interesting/puzzling questions and started trying to win the publish-the-most-articles race." davekarpf.beehiiv.com/p/can-ai-rep...

Social media plays 'huge role' in promoting traditional gender views, say experts Women's rights' groups worry about consequences of this shift in attitudes.

Why some Gen Z's embrace traditional gender roles: While young men are being taught that the way to happiness is wealth, cars, girls and physical strength, there are women being taught that the way to happiness is a really traditional idea of femininity.

Perceived Political Bias in LLMs Reduces Persuasive Abilities

How do you measure a threat in the air? Testing the universal, dynamic, and multifaceted nature of social identity threat Using the SITC Inventory, social identity threat is shown to be dynamic, multifaceted, and nearly universal.

Algorithmic content on X increases #polarization

But downranking content that expresses partisan animosity or antidemocratic attitudes significantly reduces affective polarization equivalent "to 3 years of change in United States affective polarization"

Everyday wisdom in 30” from @jayvanbavel.bsky.social @davidmcraney.bsky.social
Your attention is your most valuable resource (“pay”) so don’t let others decide how you use it. Scrolling adds up!
No “view from nowhere”, believing is seeing.
Most political content on SM is a tiny minority opinion.

This is bleak.

In countries where students spent a lot of time using devices for leisure during the school day, test scores plummeted between 2012 and 2022. In countries where they spent less time, test scores merely slid. Thus there was a significantly larger decline in scores in the countries where students spent more time using devices for fun during school hours (see Figure 1). 505 500 495 performance mean 490 485 480 475 470 465 460 455 d • Science, less device use • Math, less device use Reading, less device use Science, more device use Reading, more device use Math, more device use 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 Figure 1: Scores on standardized tests of math, reading, and science for 15- and 16-year-olds in 36 countries, by low or high use of electronic devices for leisure during the school day.

The global decline in test scores since ~2012 is highly correlated with smartphone penetration

Check out this recent @nature.com paper reporting a field experiment on X. It shows X's algorithm boosts conservative content and downranks traditional media—shifting users’ views on key issues. Switching to chronological doesn’t reverse the effect. www.nature.com/articles/s41...

This is abhorrent and repugnant. It’s further evidence of the vile and pernicious nature of these awful platforms. It makes me furious, incendiary with rage. Causes me to fall into deep sadness, melancholy and depression.

More evidence against the idea that misinformation was a moral panic

A social media post from Donald J. Trump on Truth Social, posted 9 minutes ago. The text reads: "Iran tried to interfere in 2020, 2024 elections to stop Trump, and now faces renewed war with United States:" followed by a link to justthenews.com. Below is a link preview showing the article headline "Iran tried to interfere in 2020, 2024 elections to stop Trump, and now faces possible war with U.S." accompanied by a photo from what appears to be an Iranian protest or rally, showing demonstrators holding anti-Trump signs and posters with Persian text.

I am going to need every single person who said that misinformation was a moral panic to feel enough shame and regret that they leave public intellectual life.

The boys’ club: How Epstein’s influence shaped the exclusion of women in STEM In one email, an AI researcher suggested it’s “hard to be brilliant if you are worrying if you look fat or why another woman hates you.”

Martin Nowak gave Epstein "unlimited access", an office, and he visited the campus often, "typically accompanied by young women", after his sex crimes arrest.

Harvard has now placed Nowak on leave pending further investigation. www.thecrimson.com/article/2026...

“Not American Enough" How stereotypes and feelings of status threat can explain why Bad Bunny’s set was so polarizing

“Not American Enough"

We explain why White Americans are seen as "more American" than any other group.

Stereotypes and status threats determine who gets to be seen as truly American. When people feel threatened they shrink the boundaries of inclusion.

Most college students feel a sense of belonging--almost no students feel that they don't belong.

This is true regardless of their politics, race, gender or age group.

But social media and pundits highlight the extreme outliers and make them seem representative. Don't be fooled.
