@CelsoTeteC @petrogustavo Tengan criterio, Restrepo, y crítica y autocrítica con el gobierno, que eso no les pone ni les quita. Nunca una violación al DIH será justificable.

Most people assume the best way to build "safer" LLMs is to strip all hateful or offensive text out of the training data. This paper shows, with concrete experiments, that models exposed to a small amount of such text can later be guided to avoid harmful outputs more reliably

Definition of a troll: someone whose reply reveals much more information about himself or herself than about the topic of the post.

I have made the claim, in a series of recent posts, that science is more like a tree than a linear progression and that economics, and macroeconomics in particular, can get stuck on the wrong branch of the tree. Pascal Michaillat shared a link to a paper of his with George

An LLM-generated paper is in the top 17% of ICLR submissions in terms of average reviewer score, having received two 8's. The paper has tons of BS jargon and hallucinated references. Fortunately, one reviewer actually looked at the paper and gave it a zero. 1/3

La predicción de Carl Sagan: "...La ciencia es más que un conjunto de conocimientos; es una forma de pensar. Tengo el presentimiento de una América en la época de mis hijos o nietos, cuando Estados Unidos sea una economía de servicios y de la información; cuando casi todas las

Si en un bombardeo mueren niños, niñas o adolescentes víctimas de reclutamiento ilícito, entonces se trata de una violación a los principios de distinción y de precaución del Derecho Internacional Humanitario. Sea el Gobierno de Duque o el de Petro: NO SE BOMBARDEAN NIÑOS.

I believe this paper addresses, even solves, the most relevant statistical problem of the century, including the replication crisis & the fake results in publication. I kept it concentrated, Russian probability style, just meat, unlike the looping social science "contributions"

The release of Epstein files is a standard case of negative sum game for both parts of the US elite. But because these two parts of the elite are at loggerheads they each think of how maximally to hurt the other side. In turn, this is an occasion for those who are currently

Or compare Germany with Malaysia. You are always better off in Germany, but the difference is very small at the bottom of the distribution, and is rather large around the median, after which it shrinks again.

My academic career would not have been possible if there had not been second chances. After getting my PhD, I went into consulting, then government, then industry. Only then did I realize academia was where I belonged. Short 🧵:

I love Gabriel Garcia Marquez. Imagine interviewing someone huge and this is the first thing they say to you, I'd be shaking

Testing reveals speed, not depth. Real life is about depth. RIP Jim Simons

As a Sarajevo Siege Survivor, I remember shooting intensifying on weekends when they came to hunt us for “fun”. My father Šefko, journalist, learned in April 1994 from Gen. Hajrulahović that this had been raised with the Italian Government, which he later published it in his book

Germany used to run large trade surpluses in capital goods with China (export > imports). Since the start of 2025, Germany has been running a trade deficit with China.

Scientists just found dolphins with Alzheimer’s. Yes, dolphins. The ocean’s geniuses are literally losing their memories. In a shocking discovery, researchers studying stranded dolphins in Scotland found something terrifying. When they looked at the dolphins’ brains under a

“But the ‘economics’ discipline has strong anti-bodies against ideological statements” is something difficult to take seriously, specially when it comes to macroeconomic policies implemented during crisis or emergency periods (2008, 2020).
