Scott analyzes four mechanisms that make slippery slopes real, using examples like Murder-Gandhi and playing Civilization, and proposes 'Schelling fences' as the solution - clear stopping points that people can credibly commit to defending.

Scott analyzes seven game theory concepts through his experiences playing Diplomacy, demonstrating how trust, enforcement mechanisms, revenge, and coalition-building work in practice, then proposes organizing a game among Less Wrong readers.
