Polarization by Design

Exploring How AI Persuasion Technology Transforms Democratic Governance

Read Original Paper (arXiv:2512.04047)

Paper Abstract

This research examines how advancing AI-driven persuasion technology fundamentally changes elite strategy in democracies. Rather than polarization emerging organically from social dynamics, the paper argues it becomes a deliberate governance tool when persuasion costs drop significantly. The model reveals a "polarization pull" effect where optimal strategies push society toward more extreme opinion distributions, with competing elites creating "semi-lock" regions resistant to rival manipulation.

Key Concepts from the Paper

Persuasion Cost

As AI technology advances, the cost of persuading individuals drops dramatically. Lower costs enable more aggressive manipulation strategies that were previously economically unfeasible.

Polarization Pull

When a single elite controls persuasion technology, the optimal strategy "pulls" the population toward extreme positions. This effect accelerates as technology improves.

Semi-Lock Regions

In competing elites scenarios, each side creates regions of highly committed supporters who become resistant to rival manipulation, forming entrenched political tribes.

Power Transitions

The frequency of power changes between elites affects polarization dynamics. Stable regimes polarize more; frequent transitions create chaotic, oscillating opinions.

Strategic Targeting

Elites prioritize persuading center-leaning individuals who are more susceptible to influence, gradually shifting the entire distribution while extremists remain largely unaffected.

Democratic Implications

The research reframes polarization from an accidental social phenomenon to calculated governance strategy, raising fundamental concerns about democratic stability in the AI era.
