It's easy to see shoddy research as a bad actor problem. But if AI slop like this can make it through editors and peer reviewers, it means there are systemic problems at work. And I'd argue that at least part of the problem is the overwork culture in academia-- pressure to do more while caring less.
"Runctitiononal features"? "Medical fymblal"? "1 Tol Line storee"? This gets worse the longer you look at it. But it's got to be good, because it was published in Nature Scientific Reports last week: www.nature.com/articles/s41... h/t @asa.tsbalans.se

Even if you know the story of Clever Hans, this is a very worthwhile thread:
Wilhelm von Osten was a German math teacher, mystic, phrenologist. He also owned a very clever horse he named HANS.
Around 1894, he took his horse on tour, demonstrating his exceptional number sense skills.
van Osten would ask a question: "What is 2 x 6 ?"
Clever Hans would tap his hoof 12 times.

Dear Chancellors:
I'm writing with regard to the President's Postdoctoral Fellowship Program (PPFP) and the program's associated faculty hiring incentive.
As you know, for more than 40 years, PPFP has provided postdoctoral research fellowships, professional development, and faculty mentoring to scholars in all fields whose research, teaching, and service advance the academic and research missions of the University of California.
Since 2003, UC campuses that hire current and former PPFP fellows into ladder-rank positions have been eligible for a hiring incentive funded by the University that provides support for newly hired fellows for five years. Since the creation of the incentive, more than $162 million has been invested by the University to support PPFP faculty hires. This commitment has enabled our campuses to successfully recruit and retain outstanding faculty across a range of disciplines.
Given the myriad challenges currently facing UC - including disruptions to billions of dollars in annual federal support, as well as uncertainty around the state budget- reasonable questions were raised in recent months about whether the University could maintain the commitment to current levels of incentive funding. After considering a recommendation to sunset the incentive program due to these significant fiscal constraints, I consulted with all of you as well as faculty and campus academic administrators and systemwide Academic Senate leadership.

For non-academics who might not understand why:
1. Sen. Warren is still a Harvard professor so this is a call coming from inside the house
2. As a tenured law prof, Warren knows it is a VERY big deal from a labor standpoint to call on Harvard to ignore tenure. The bar for this is HIGH.

Per CNN, Elizabeth Warren is calling on Harvard to cut ties with Larry Summers after Jeffrey Epstein's emails released last week by House Dems featured Summers making sexist comments + asking for Epstein’s romantic advice.

A senior academic using mentoring as leverage to obtain sex is a contemptible abuser of power.
Summers conferred with Epstein frequently about how to extract sexual favors from a Harvard econ grad (AB '04, PhD '09)
