# Belief places and spaces: Mapping cognitive environments

## TL;DR

This paper introduces a system for mapping belief environments and perspectives within social groups, using agent-based simulation and tabletop role-playing game data to visualize shared and individual belief landscapes.

## Contribution

It presents a proof-of-concept method for creating belief maps from social interactions, which can be extended to larger datasets like social media discussions.

## Key findings

- Maps show shared narrative environments and subgroup perspectives
- Agent-based simulation effectively models belief space dynamics
- Method is generalizable to other data sources like social media

## Abstract

Beliefs are not facts, but they are factive - they feel like facts. This property is what can make misinformation dangerous. Being able to deliberately navigate through a landscape of often conflicting factive statements is difficult when there is no way to show the relationships between them without incorporating the information in linear, narrative forms. In this paper, we present a mechanism to produce maps of belief places, where populations agree on salient features of fictional environments, and belief spaces, where subgroups have related but distinct perspectives. Using a model developed using agent-based simulation, we show that by observing the repeated behaviors of human participants in the same social context, it is possible to build maps that show the shared narrative environment overlaid with traces that show unique, individual or subgroup perspectives. Our contribution is a proof-of-concept system, based on the affordances of fantasy tabletop role-playing games, which support multiple groups interacting with the same dungeon in a controlled, online environment. The techniques used in this process are mathematically straightforward, and should be generalizable to auto-generating larger-scale maps of belief spaces from other corpora, such as discussions on social media.
