Are a few people ruining the internet for the rest of us?
Why does the online world seem so toxic compared with normal life? Our research shows that a small number of divisive accounts could be responsible – and offers a way out

Only a small % of people engage in toxic activity online, but they’re responsible for a disproportionate share of hostile or misleading content on nearly every platform
Because super-users are so active, they dominate our collective impression of the internet www.theguardian.com/books/2025/j...

The most precious commodity you have is your attention. You don’t have to waste it on poor-faith debates or arguments with strangers if you don’t think they’ll be productive. You can prioritize the things that matter to you and make your life richer.

This is a scandal.
Public universities should be banned from paying these insane buyouts for college coaches.
No pro sports teams are paying $33 million to fire their incompetent coach, so why are colleges paying this kind of money?!?

SOURCES: Michigan State is firing head coach Jonathan Smith, @theathletic.com has learned.
He went 9-15 in two seasons, including 1-8 in the Big Ten this year. (ESPN first reported).
MSU players meeting called for 2:45. Smith has a $33 million buyout (with offset).

Really interesting thread. I’ve experienced some of this in my classes, too. About 15-20% of my students are really struggling. I’ve seen some universities implement a first year seminar to help students with some of the more fundamental skills of university work. I think this is a great idea.
An issue we're seeing at all levels of university is that many students are simply refusing to do *anything*. They aren't reading the syllabus, aren't following assignment guidelines, aren't engaging with material, ignoring deadlines. And this might seem like old news, but it truly has ramped up.

Miles Hewstone has now been removed from many prestigious positions due to the media coverage.
He was able to keep all these positions for years after he was investigated for sexual harassment.
We urgently need to fix academic societies to stop known harassers from maintaining power over others.

"Prestige bias" is one of the strongest forms of bias in academia.
Reviewers rank paper submissions from top-20 institutions and non-students higher, but this goes away with blinded reviews.

A study of 274,316 students finds that low-SES students are much less likely to wait for offers to preferred schools. This led low-SES students to ultimately enroll in programs they liked less and that were less prestigious.

My wife was sexually harassed by Miles Hewstone as a phd student. He was still asked to review her (and other women he harassed) for jobs and promotions. This is so fucked up.
Thankfully, she and many other women testified against him and something was finally done. This is her take on his case:

New research finds evidence of evolutionary fitness benefits of intergroup violence in chimps--one of our closest ancestors.
After killing many of their neighbors and reducing their collective strength, chimpanzees may have insulated their infants against this threat.
