    Want to read an insane tenure denial story? I was denied tenure at MIT in 2018. I was the only Hispanic faculty at my department, had 13k+ citations, 2 books, & papers in Nature, Science, & PNAS. I was never given a reason & the only letter I got told me to check the website./1🧵

    After advising PhD & Master students for over a decade, there is one thing I find most students need to unlearn: the half-ass work mentality acquired during years of tests and homework. Let me explain (thread 🧵). 1/N #AcademicTwitter

    Today I am leaving the US. With my family we are exploring a new life in the south of France. I’ve been in the US for more than 16 years. I earned my citizenship & experienced many ups & downs. But I am grateful. The US was good to me in many ways ... /1

    *I have more to tell. I could probably fill a book with the psychological damage I experienced at “the institute.” But as you may understand these are difficult things to talk about. They are the storm that lives within me & wakes me up at night. It took me years to share this.

    I finally got “an answer.” The president of MIT told me that tenure was not about research, productivity, or merit. It was about office politics & being liked by your department. He didn’t mean it in a bad way. I think he was being kind & honest. So I ask him if I should appeal.

    “Look Cesar, the truth is that, if you are a mediocre researcher, but your department wants to keep you, they’ll find a way to keep you. And if you are a strong researcher, and your department wants to get rid of you, they’ll find a way to get rid of you.”

    There is a lot of discussion of bias in economics. This discussion is justified & needed. What I can add to this is some stories on how economists treat people from outside the field. Let me share with you a few bone chilling stories of what I’ve been through 🧵/1 #EconTwitter

    True for so many disciplines. It applies also to cumbersome use of language.

    I did not appeal. That year changed me. Before then I believed in an imperfect meritocracy. After all, scientific work is reproducible and verifiable. Its adoption is also expressed imperfectly in citations. It was time to grow up & accept the cynicism.

    “I am sorry, I am not going to be able to simply talk about research. I just learned that my tenure case was denied.” He looked at me & said instantly: “But if your case had been approved, who in the senior faculty would have won?” He understood the game.
