New paper out.

What happens when you make a model that includes realistic details about how people discuss ideas and decide how to act upon them? The answer is that with just 3 such elements of realism, one can mathematically explain the emergence of commonly observed situations, such as reaching a consensus and exchanging opinions, but also the separation of ideologies and the appearance of stable polarization. Not only this, but one can also account for phenomena such as peer pressure, cognitive dissonance, tactical voting and toxic idealism ( @benroyce I told you I was going to do it 😀 ) and prove how they affect the final state of the system.

#publication : Can a Single Line of Code Change Society? The Systemic Risks of Optimizing Engagement in Recommender Systems on Global Information Flow, Opinion Dynamics and Social Structures

We demonstrate that engagement-maximizing algorithms necessarily lead to increased network toxicity and fragmentation of opinion space.

#preprint We have a new #ABM called NormAN (for ‘Normative Argument Exchange Across Networks’) which we hope will help build bridges between research on #OpinionDynamics and #Argumentation research.

It captures the exchange of arguments by #Bayesian agents in a ground truth world based on a #CausalGraph. Code is #Netlogo with #R (netlogo python coming soon).

Take it for a spin!

A Bayesian Agent-Based Framework for Argument Exchange Across Networks

In this paper, we introduce a new framework for modelling the exchange of multiple arguments across agents in a social network. To date, most modelling work concerned with opinion dynamics, testimony, or communication across social networks has involved only the simulated exchange of a single opinion or single claim. By contrast, real-world debate involves the provision of numerous individual arguments relevant to such an opinion. This may include arguments both for and against, and arguments varying in strength. This prompts the need for appropriate aggregation rules for combining diverse evidence as well as rules for communication. Here, we draw on the Bayesian framework to create an agent-based modelling environment that allows the study of belief dynamics across complex domains characterised by Bayesian Networks. Initial case studies illustrate the scope of the framework.
