Steven Johnson's "Farsighted" explores the under-appreciated skill of making significant, long-term decisions. He contrasts historical figures like Charles Darwin, whose decision-making process was rudimentary, with Benjamin Franklin's "Prudential Algebra," a numerical weighting system. Johnson argues that even these methods are intuitive and that modern "decision science," a blend of behavioral economics, psychology, and management, offers more robust techniques.

Johnson examines complex choices, such as President Barack Obama's decision to authorize the raid on Osama bin Laden's compound, showcasing how decision science was applied. He suggests individuals adopt these methods for personal life choices, which are often less calculated than trivial ones. The author recounts his own experience using decision-scientific strategies to move his family from New York City to the Bay Area, involving a "full-spectrum analysis" and a contract with his wife.

"Farsighted" advocates for structured processes like "design charrettes" and "scenario planning," used by organizations like Royal Dutch Shell and military planners. These methods involve breaking down problems, seeking diverse perspectives, challenging assumptions, and mapping variables. Johnson aims to empower individuals to be active authors of their life's story, rather than passive observers, by engaging consciously with how they change and make consequential choices. The book emphasizes that while big decisions can feel like they "make themselves," understanding and applying decision-making principles can lead to more confident and satisfying outcomes.
