Still processing that an economic advisor to multiple administrations, business leaders, and top institutions was asking a known sex trafficker of minor age girls to be his wingman for attempting to coerce his academic mentee into a sexual relationship—years after he said that women aren’t as smart

I hope Larry Summers being exposed as lacking discernment and judgement —as a liar, an abuser of his mentees, and the buddy of a child trafficker — will lay to rest the myth that skill on the math section of the SAT is the highest and most advanced form of human cognition.

I am not being hyperbolic when I say that how Harvard and the economics profession respond to Larry Summers will determine who makes up the next generation of economists.

THIS IS BIG

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 female wolf has been doing something unusual on the Central Coast of British Columbia. She's learned to pull crab traps up from the water, yanking on a rope to bring it to the surface. But is it tool use? Very fun story from @phiejacobs.bsky.social for @science.org
Have wild wolves learned to use tools?
Video captures a lone female pulling crab traps out of the water, but does it count as tool use?

Could argue the misogyny Summers expressed both publicly while president of Harvard and in emails to Epstein says more about the culture at our most elite institutions than any of the frontpage freakouts over academia in the past few years but hey

"Peril" as in "Yellow Peril"?! Summers (who was married at the time) manages to be racist, sexist, and just plain gross in emails with his "wingman" Jeffrey Epstein.

Never tell me again how the real problem with academia is that it is "too woke."

It is interesting to me how the media seems far less interested in Trump's Murder Memo than you'd expect. Only a few reporters seem to be even trying to get a hold of it, and very few commentators are talking about it. Contrast that with Bush's torture memo, which was a national obsession. Weird.
Trump's illegal murders in the Caribbean just got worse. An internal DOJ memo on the bombings says the victims are waging war on the US, but per NYT, it extensively cites the WH's *own claims* to this effect as evidence!

It gets even darker than that. 1/

I wanted to share probably the most important sermon I’ve given and it’s while I’m being arrested. It’s torture pure and simple what happens at #Broadview. I’m ok, though I was thrown to the ground and choked with my pectoral cross. A review of the video shows I was peaceful - did I deserve this?

His sincere updates on his attempted relationship with a student are so creepy and cringe, and then you remember the person Larry Summers is pouring his heart out to is DISGRACED CHILD SEX TRAFFICKER JEFFREY EPSTEIN, IN THE YEAR OF OUR LORD TWO THOUSAND AND EIGHTEEN
The emails have Summers reporting to Epstein about his attempts to date a Harvard economics student & to hit on her during a seminar she was giving.
