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 explains why 'wanting' and 'liking' diverge by examining reinforcement learning mechanisms like context-dependence, intermittent reinforcement, and hyperbolic discounting, concluding that this undermines the concept of stable preferences.

Scott explains time and effort discounting through examples like candy placement affecting consumption, argues that hyperbolic discounting creates preference reversals, and suggests these are better understood as reward functions rather than true preferences.

Scott expands on Wei Dai's master-slave model of the mind to explain akrasia and self-deception, proposing that the unconscious (U) uses the conscious mind (C) as a PR agency to signal socially admirable values while pursuing selfish goals, requiring just enough genuine support of C's principles to maintain credibility both to others and to C itself.

Scott tests picoeconomics theory by creating a formal written oath to study two hours daily, which successfully works by creating the same psychological pressure as serious deadlines, and he provides practical advice for others to try this technique.
