The #trajectory of getting a paper published is never easy. I’m particularly proud of Xiuxiang(Shawn) Pan (my #mentee from Groningen) for pushing this #migration paper through to the final stage—officially published! doi.org/10.1002/psp.70379
A press release by Illinois's news bureau about the recently published paper by my student Sinyee Lu and me. I've found a good location for the photo shoot😃 news.illinois.edu/volatile-w…
After several years with multiple rounds of revisions, this project on assortative mating with @YifanShen1 (based on his dissertation) finally sees the light of day today in Demography. Congrats, Yifan!

My first research paper was rejected by five journals.
One review said: "The research is fine. The paper is not."
That stung, because I thought good research was enough. It is not. A paper is not judged on what you know. It is judged on how you let the reader see it.

للمهتمين بالبحث العلمي 📚
هذه من أفضل الأوراق اللي قرأتها عن كتابة ونشر الأبحاث. 👌
3 محررين من مجلات طبية كبرى يشرحون بشكل عملي ماذا يريد المحرر فعلًا من الباحث، وأبرز الأخطاء اللي تسبب رفض الورقة.
مفيدة جدًا لأي شخص يبدأ بالنشر العلمي أو يطور طريقة كتابته للأبحاث.

This article should be mandatory reading for every medical student, PhD candidate, researcher—and honestly, for anyone who mistakes expertise for certainty.
“The importance of stupidity in scientific research” sounds provocative, almost offensive. But Martin Schwartz is not glorifying incompetence. He is describing the real operating system of discovery.
Science is not built on knowing.
Science is built on tolerating not knowing.
That distinction matters.
Most of education rewards correctness.
School teaches us to answer.
Exams reward speed, certainty, and precision.
You feel intelligent when you get things right.
Research is the opposite.
Real research begins exactly where competence ends—at the frontier where nobody knows the answer, including the people you thought must know.
That moment is psychologically brutal.
You ask the expert.
The expert shrugs.
You assume you’re missing something.
Then you realize: no—this is the work.
You are not failing.
You are standing at the actual boundary of knowledge.
That feeling—“I must be stupid”—is often not a sign of inadequacy.
It is often the first sign that you are finally asking an important question.
Medicine struggles with this.
We train doctors to avoid uncertainty, to fear being wrong, to perform confidence.
But the best clinicians and the best scientists know how to sit inside ambiguity without collapsing into fake certainty.
This is why AI in medicine also deserves caution.
Systems trained only to reproduce established answers may become extraordinarily good at passing exams while being terrible at discovering what matters next.
Guideline intelligence is not the same as scientific intelligence.
Discovery requires productive stupidity:
the willingness to stay with the uncomfortable,
to look ignorant,
to ask naïve questions,
to be wrong repeatedly without protecting your ego.
Most people want the authority of expertise.
Very few want the humiliation required to earn it.
But progress lives there.
Not in certainty.
Not in performance.
Not in sounding smart.
In the quiet discipline of saying:
“I don’t know… yet.”
And continuing anyway.
Happy to share a new publication resulting from Abby Beck's dissertation in civil engineering (@UofIllinois 2024), where she ingeneously applied the individual Theil measure I proposed in SMR (2022) to help inform electricity distribution equity! urldefense.com/v3/__https://…$
I have a new paper published online today about the positive impact of children's education on parents' life satisfaction (as corresponding author).

📢New paper!
With French data on the grandchildren of immigrants @LGDrouhot @mathieu_kf @IchouMathieu #L_Caron provide rare insights into long-term integration processes!
Despite substantial convergence, lasting disadvantages persist for specific groups!

Fascinating paper just published in Science.
The authors analyze the career trajectories of top performers across multiple domains, including Nobel laureates, elite chess players, Olympic gold medalists, and more.
Their central finding challenges a common belief.
Intensive, single-discipline training at a young age does confer an early advantage, but this advantage fades over time.
By contrast, individuals exposed to multidisciplinary practice early in life tend to start more slowly. Yet, over the long run, they are more likely to reach world-class performance, eventually overtaking early specialists, who often plateau just below the very top.
An important reminder that breadth early on can be a powerful investment in long-term excellence.
