10.2 Limitations and Boundary Conditions
10.2.1 Theoretical Limitations
Equilibrium Assumptions: Many results rely on equilibrium concepts that may not describe real bounded-rational agents
Common Knowledge Requirements: Strategic analysis often assumes common knowledge of rationality
Preference Stability: Models frequently assume fixed preferences during voting process

10.2.3 Scope Boundaries
Static Focus: Primary analysis focuses on single-election scenarios rather than iterative processes
Deterministic Mechanisms: Limited exploration of stochastic or random-social-choice mechanisms

10.5 Closing Thoughts
The mathematics of voting and social choice theory remains a vibrant and essential field of study. As societies face increasingly complex collective decisions—from climate change mitigation to AI governance, from pandemic response to multi-planetary settlement—the need for rigorous understanding of preference aggregation only grows.
This dissertation has sought to contribute to that understanding by:
1. Grounding analysis in solid mathematical foundations
2. Developing methodological tools appropriate to the complexity of the subject
3. Generating insights that bridge theory and practice
4. Opening directions for continued research and application
The central insight remains both simple and profound: while no perfect method exists for aggregating diverse preferences into collective decisions, thoughtful analysis and design can produce systems that are fair, effective, and legitimate enough to serve as foundations for just and functioning societies. The work continues—not in pursuit of an unattainable perfection, but in the refinement of tools for self-governance in an increasingly interconnected world.
