indeed, the nation needs builders, electricians, carpenters not lawyers and accountants... the only challenge is: soft and hard societal status programming needs to change big time to make that transition happen.

AIPNET gives that map. Use it to target subsidies to high‑spillover nodes, speed green tech adoption, and shape industrial policy. Learn more about the AIPNET on aipnet.io.

AIPNET builds a production‑network graph to spot critical inputs like gallium and track China’s rising centrality. Bottom line: knowing the network lets you move up the instrument ladder—from blunt quotas to precise taxes—just as a monopolist refines pricing with consumer data.

if bargaining power shifts, quotas are better. You need to know the network. Network knowledge is the game changer. The paper shows that better maps of who is linked let policymakers pick the right tool—linear taxes, quotas, or nonlinear schemes—matching shock patterns.

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...

On limitations to survey experiment research and attacks on academia
In the past I had shared some reflections or concerns on some challenges that I see arise with survey experiments and potentially with the information experimen

Some thoughts on here: www.trfetzer.com/on-limitatio...
Academic incentives—attention, citations, activism—can distort research agendas. When scholars become perceived authorities, they may be called upon to advise policy, amplifying influence. This cycle can fuel attacks on academia and erode public trust. We need transparent, diverse inquiry.
A persuasive effect in a lab doesn’t guarantee real‑world change. People self‑select into news that fits their priors, and counter‑framing by elites often dominates. Policy advice based on partial equilibrium findings can mislead; we must consider general‑equilibrium impact.
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 should add to these to highlight the public service more broadly & the decline in perceived performative state capacity in the UK. The role of social media, plus adding references to the work on incidence of the economic cost of Brexit across concepts of the spatial economy: x.com/fetzert/stat...
