Method for Mitigating Attention to Inappropriate Content Based on Attention Dynamics Model

Naoki Hirakura

TL;DR

The paper tackles mitigating attention to inappropriate content in the attention economy by proposing an imitation-based intervention on a small competitive network of information disseminators, avoiding broad moderation. It uses spectral dimension reduction to show that the one-dimensional attention observable decreases as the largest eigenvalue $\lambda$ of the transposed adjacency matrix increases, and formalizes an imitation mechanism that raises $\lambda$ by aligning an imitator with a high-centrality target, i.e., $A^* = \frac{K \zeta}{1+\zeta \mu \lambda}$. The authors derive a perturbation-based success condition requiring the imitator and target to be arranged by eigenvector centrality and validate the approach with extensive simulations on sparse, dense, and heterogeneous networks, including robustness to noise. While promising as a non-moderation intervention, the work notes limitations such as equal-influence assumptions, lack of content-type awareness, and the need for real-world validation and integration with detection techniques.

Abstract

The expansion of the attention economy has led to the growing issue of inappropriate content being posted by profit-driven users. Previous countermeasures against inappropriate content have relied on moderation, which raises ethical concerns, or information diffusion control, which requires considering larger scale networks, including general users. This study proposes an imitation strategy as an intervention method that does not rely on moderation and focuses on a relatively smaller scale competitive network of information disseminators rather than the entire social network. The imitation strategy is a novel approach that utilizes increased competition among information disseminators through imitation to reduce attention to inappropriate content. Through theoretical analysis and numerical simulations, I demonstrate that the imitation strategy is more effective when nodes with higher eigenvector centrality are selected as targets and nodes with lower eigenvector centrality are chosen as imitators.
