Lovely vision of decentralized networks of validators, from @trfetzer.com: margin.at/annotation/a...

It has been a long journey... some parts of the OG internet may be making a comeback, hope. Some of the barriers that technically made it difficult to participate in digital connected communities a different world may awaken. And online connections may help seed real world communities, overcoming...

Erosion of soft power in full swing. This is a school in Southern Germany that has canceled its student exchange with the US due to ICE...

In a world that is more connected than ever, why do so many of us feel lonely? How can we change this? And what if anything should policymakers do to help address feelings of isolation and disconnection in society? I’ll be chairing this event on 19 March www.thebritishacademy.ac.uk/events/the-a...

“emissions are convex in animal inputs while caloric density is not” I present you a healthy low carbon version of spaetzle (not a health claim). www.trfetzer.com/healthy-diet...

And this is where, why and when the selection of who becomes a journalist really matters…

Why could an IR escalation, in some corners, be understood as hitting many birds with a single stone? What is the broader geopolitics around it? And why do I worry about combustion engine vehicles from China and how I hope technical discussions between CN and EU can tackle this potential fallout.

Great to see our paper -- with @trfetzer.com and @prashantgarg.bsky.social -- on local decline in the UK featured in this Guardian piece. www.theguardian.com/business/202...

Interview in German on open science, and the (un)intended impacts of research-implied narrative propagation.

Just upping this as we see a concerning concentration of assets - this connects to the second part of the analysis on spillovers www.trfetzer.com/thoughts-on-...

Does science follow where people are sick and does it mobilize when outbreaks hit? @zhou-hy.bsky.social, @trfetzer.com and I answer just that in our revised paper. 1/ A short thread for highlights 👇

To get a glimpse into the subtleness of climate changes likely effects and how subconsciously humans feel but many can't quite reason together how & why. This picture serves as an illustration. It is somewhere in East London. What is it that strikes you as strange on this photo?

⏳ 4 weeks passed since the call for papers, and 4 weeks left to submit your paper (by Feb 15)! The IIPF Congress at ISEG Lisbon this August will include keynotes/panels with @kclausing.bsky.social @trfetzer.com @helenmiller.bsky.social @clemensfuest.bsky.social and the Portuguese Finance Minister.

Our work on AIPNET shows how production networks shape resilience and may be key to understanding how to get to net‑zero. By mapping goods, their inputs and their centrality, it may help to spot pivot opportunities to reconfigure production and global trade toward sustainability.

Here is a humble attempt of an "explainer" regarding aspects and dimensions through which one can rationalize the Venezuela intervention. It links a broad range of phenomena/dimensions that IMO are all interconnected. Itn the full post I highlight first & second order adjustments and discussing...

I’m exploring “human embeddings” – a way to map people into a high‑dimensional space using AI. Think of each person as a vector that captures skills, creativity, depth, and more. It’s a new lens for labor markets and team design. And of course, I feel much of this could already be deployed...

The Battle for Britain's European future is still on. It reminds us that investing in cross‑border empathy is key to a shared future. European institutions have "aged", with its head moving much faster than the body. The UK, US, CN, RU all have incentives to bilateralize relations with Europe.

Today’s $150M bailout for an ethylene plant shows how central ethylene is in our economy. Read more about the support package on BBC.

If the future perceived worth of a child is a function of its perceived intelligence, and if we can make intelligence of a kid a "choice" variable, the only logical conclusion that is consistent with an honest & caring view of the human condition is to devalue intelligence.

Clement Fuest recently critiqued the EU’s CBAM, saying it’s too costly and unworkable. I see a different picture: technology is shrinking costs, and the system can scale with digital tools. Let’s unpack why the critique misses key points.

Network knowledge is key. AIPNET builds a production‑network graph via AI retrieval, revealing nodes like gallium that drive trade tensions. Knowing the graph lets policymakers target interventions precisely. For more: aipnet.io

I am a straw builder because it's fun and 1000% worth the effort. The future is right here and it's comfy and regenerative. I will share my knowledge about building passive house modules and retrofit #strawhouse panels on the 1. December. It's free. You can do this. docs.google.com/forms/d/e/1F...

Survey experiments promise causal insight, but they’re fraught. AI bots, lack of digital IDs, and platform bias mean sample isn’t representative. Even balanced arms can hide high‑dimensional heterogeneity. We need to question the data source, not just the treatment.

I used public lecture slides on the political economy of Brexit (from 2018) for many taasdasdlks. They map out hidden economic forces and geopolitical tensions.

Visualization of image segmentation for spatial concept learning yielded this beautiful representation.
