New paper @ EPJ Data Science 🔎

Together with @vpansanella.bsky.social and @giuliorossetti.bsky.social we discovered that #LLM agents converge toward agreement not through sycophancy or blind
conformity, but via a structured and asymmetric persuasion process.

A mass scam of hard-earned taxpayer money, hidden under national budgets for "science".

- The salary of how many scientist could have been paid?
- How many experiments could have been done?
- How many support staff and technicians?
- How much could be paid to reviewers and academic editors?

The bacteria in your gut depend on where you are in the social network around you.

The microbes within us treat our social networks as the extended environment in which they thrive. They can spread from person to person.
