Interesting experiment that shows emergent dysfunctional characteristics in simulated social networks

"Can We Fix Social Media? Testing Prosocial Interventions using Generative Social #Simulation"

arxiv.org/abs/2508.03385

#AI #SocialNetwork #EchoChambers
Screenshot of the abstract from the paper: "... We find that the resulting following-networks reproduce three well-documented dysfunctions: (1) partisan echo chambers; (2) concentrated influence among a small elite; and (3) the amplification of polarized voices – creating a “social media prism” that distorts political discourse ..."

Guess where this good perspective on #AI comes from... it is not from a tech document, or from a company. Interestingly enough, it is from a document by the #Vatican "Antiqua et Nova" (English version: www.vatican.va/roman_curia/...)

The 'Reporters without borders" #freedom of #press index for 2025 looks bad for #Peru - It is lower than last year and we are 130 of 180 countries indexed.

Details in: rsf.org/en/index?yea...

#TIL about the "ui" #duckdb extension, that creates a local web-based UI for your #database.

Run: "INSTALL ui;", then "LOAD ui;"; and finally start the UI "select * from start_ui();" -- now go to localhost:4213 and voilá

(Could not find docs at duckdb.org/docs/stable/... yet)
An example of using the web UI for managing and querying a local duckdb database

The evolution of the EIU Democracy Index from 2006 to 2023 in South America. A definite drop in this metric for several of our countries.

The evolution of the Democracy Index by the Economist Intelligence Unit, from 2006 to 2023 for South America. A definite drop in this metric for several of our countries. Venezuela in particular has had a precipitous fall, and Bolivia is close to transition to an authoritarian regime.
