Cómo DETECTAR a un PSICÓPATA INTEGRADO: 5 Señales A Tener En Cuenta YouTube video by Judith Tiral

Aquí hay una breve explicación del autor, Vicente Garrido, sobre qué señales hay que buscar para detectar psicópatas integrados y las diferencias con los narcisistas. No hay que ignorar a la intuición, el gut feeling y evaluar siempre acciones no promesas.

Ahora voy a leer 👇Aborda cómo detectar a psicópatas integrados: personas que no cometen delitos graves de violencia, pero causan daños significativos en la vida personal y en instituciones de la sociedad, incluyendo la política.

I love the book and reactive programming! I wish I could apply that kind of programming more frequently. How do I manage? I practise a tonne with the book. Read a chapter at a time and interact with R at the same time. Try to create my own examples as well.

This is one of many reasons I’ve refused, for decades, to accept performative diversity roles. Being a brown migrant woman does not make me uniquely qualified to fix institutional failures rooted in centuries of neglect.

Minorities in academia are expected to overperform, stay silent, and endure stereotypes (e.g, you don’t know how to write, are poorly educated). This is a minority tax: taking extra unpaid labour and diversity duties that don't count towards promotion.

Oh yes, I love it! It gets me unstuck every time. The whole package is amazing. Thanks.

Carl Friedrich Gauss: The Prince of Mathematics! (1777–1855) YouTube video by BMResearch

The Prince of Mathematics! (1777–1855)
From humble beginnings, Carl Friedrich Gauss reshaped science, from number theory, celestial mechanics to probability, statistics, and geometry.

A mind of rare depth and clarity.

Women with names perceived as masculine are less likely to be omitted from citations than those with feminine names. Men with feminine-sounding names are more likely to be omitted than men with masculine names, suggesting citation bias based on gender perceptions.

Summer project: reading 👇 and building new maps. A very good guide for spatial thinking in criminology and R.

Astronomers had noisy observations of comet positions and needed to estimate their orbits, like ellipses or parabolas. But errors made this tricky. In 1805, Legendre introduced least squares to find the orbit that best fit the data by minimizing squared errors.

Did you know that the widely used method of least squares was born chasing comets?
Legendre published it in 1805 to estimate their orbits
Gauss claimed he’d used it privately since 1795
Legendre: I published it first
Gauss: I published why it works… in 1809.

Is violence learned or inherited? Is it written in our genes or shaped by experience? Can anyone become violent?

Roberto Colom and Antonio Andrés Pueyo tackle these big questions in 👇

BTW, Darwin admired Galton’s scientific work, but he did not endorse eugenics. He recognised that some traits are inherited, but he also believed that social outcomes depend heavily on factors such as education, opportunity, and habits, not just heredity.

You can find some of the correspondence between Galton and Darwin here: galton.org/letters/darw...

Long before emails and AI.

In 1874, Francis Galton, father of regressions & cousin of Charles Darwin, wrote a book based on a questionnaire sent to scientists about their childhood, families and mental traits.
Praised for pioneering survey methods but criticised as paving the way to eugenics

Oh yes, I had seen it. That's in my to-read list as well.

Want to understand how probability and statistics became science?
Stephen Stigler's The History of Statistics is a brilliant, readable dive into the origins of statistical thinking before 1900.

Mexico’s femicide laws were a landmark reform. But in a system where 98% of crimes go unpunished, laws without enforcement don’t save lives.

Also:
✅ 17 subgroups (age, education,occupation,marital status, etc)
✅ Stable without/with alternative controls
✅ Placebo tests with 24-month pre-trends confirm parallel trends
✅ Robust to synthetic DiD

🚨 Updated paper on femicide laws in Mexico.

After years of work, I find no evidence these laws reduced femicides, female homicides, suicides, or disappearances using dif-in-dif, even after testing
✅ Sentence severity
✅ Parallel reforms (unilateral divorce, divorce asset compensation, abortion) 🧵

Last week I said I’d buy those stats books 📚
Today they arrived!
You also can find them for free here:

The best book for breaking the “I’ll write when I feel like it, or when I finally find time” curse is
How to Write a Lot by Paul J. Silvia.

No fluff. No excuses. Just a system that works.
Buy it, read it, reread it. Highly recommend.
