In an opinion article at WSG the previous president of Dartmouth made some nice points about universities. I agree with most of them. The one I disagree with? Campuses being apolitical. And this is why: medium.com/@kpelechrini...?
Should universities stay away from politics?
I recently read this opinion article on WSJ and while I agree with the majority of the points made, the suggestion that universities should…

Defend your freshly shoveled spot from aggressive drivers! Pick a chair defense wisely bc you have limited inventory. Folding chair > lux car, but watch out for beaters not caring ab ANYTHING. How long can you hold your spot? Play now & share your results: sites.pitt.edu/~kpele/chair...

Well it would not be a snowstorm in #Pittsburgh without parking chairs. But if are not able to defend your spot with a physical chair, you can do it virtually: sites.pitt.edu/~kpele/chair...
This is a Rock, Paper, Scissors-type of game but with chairs and cars. Enjoy!

I guess we will now see whether checks and balances really work or if it is a myth. I wouldn’t hold my breath though

Is this good? Full study: www.kielinstitut.de/fileadmin/Da...
Of course this is a short-term study -- so it remains to be seen if for example this leads to more reshoring (which I highly doubt as well)

What this whole situation in Minnesota shows to me is that we are not talking about just division anymore but about manipulation. People are being fed simplified stories that turn fellow citizens into enemies and complex problems into easy villains. Many are fighting against imaginary [1/3]

One of my favorite AI tools as of late is Gemini's Storybook. Instead of reading the same books every night with my 5-year old, we just create our own based on his imagination (which of course always involves dinosaurs). gemini.google.com/share/8b490d...

Polls have been used to manipulate public opinions etc. for decades. The following excerpt is from a paper from 1984 (from all years) "The Impact of Polls on Public Opinion". The "evolution" of this are prediction markets. Wtf is this from polymarket? This is what happens when [1/3]

I am not a NY's resolution guy but if you are, my suggestion would be for your resolution to be **to delay your real resolution** January is the worst possible month to launch a fragile habit: motivation is inflated & expectations are maximal #NewYear2026 [1/3]

We put this screen at the City County Building 4-5 years ago as part of the Pitt Smart Living project. Glad to see it still running! It’s a bummer that the project was during COVID and didn’t allow us to do some cool stuff with #PublicTransport

For ADs and college presidents/chancellors: NIL shouldn’t be a yearly scramble.
Endowment logic: invest in markets + innovation, preserve capital, fund athletes from returns—not donations.
Less donor fatigue. More long-term stability. Stop borrowing the future to pay the present.

Bro really got a "peace prize" equivalent to the stickers parents give to their kids when they have a meltdown. And all these while his "department of war" is out there killing civilians off the coast of Venezuela... But it's FIFA we are talking about; birds of a feather...
WATCH: Trump knows he can’t really win a Nobel Peace Prize so he just had FIFA give him a made up award. Sad.

Amid the chaotic season it’s been fun to watch Flagg’s elite motor and IQ. Here he closes out, then contests a shot at the rim, grabs the rebound and scores in transition. But look at the contest. He sees the goal tending waiting to happen and avoids it!

These #NBA executives would benefit greatly from my upcoming book on Bayesian thinking (with FO decisions and roster building as its testbed). I’d donate them a copy when it is out but I am sure they can afford it…🤷🏻♂️

Greed always ends in the same way, whether it is greed for power, greed for money or anything else. The cup drains every single time.

"If you make your hobby your job you won't have to work a single day" they said. But what if job dynamics and politics spoil the very things you enjoyed? Then your hobby dies, the work sucks, and you're left with an empty shell where joy used to be.
