Key Takeaways from Algorithms to Live By

  1. Apply the 37% rule to optimize hiring, dating, and real estate decisions.
  2. Balance new experiences with favorites using the explore/exploit algorithm.
  3. Prioritize tasks via scheduling theory’s “shortest processing time first” principle.
  4. Reduce decision fatigue by caching frequently used items for quick access.
  5. Update beliefs systematically using Bayesian inference for adaptive decision-making.
  6. Avoid overthinking by halting analysis when predictions risk overfitting.
  7. Manage overloaded to-do lists with optimal stopping to drop low-impact tasks.
  8. Negotiate conflicts using game theory’s regret minimization strategies.
  9. Sort items only when future search benefits justify organizational effort.
  10. Simplify others’ choices through computational kindness for efficient decisions.
  11. Allocate resources using the multi-armed bandit’s explore/exploit balance.
  12. Optimize apartment hunting with the 37% rule’s “look then leap” phase.

Overview of its author - Brian Christian

Brian Christian is the bestselling author of Algorithms to Live By: The Computer Science of Human Decisions and a leading voice exploring the intersection of technology, ethics, and decision-making.

A Brown University and University of Washington graduate with degrees in computer science, philosophy, and poetry, Christian bridges technical rigor with philosophical inquiry. His work examines how computational principles apply to everyday life, a theme central to Algorithms to Live By, which he co-authored with cognitive scientist Tom Griffiths. The book became a #1 Audible bestseller and was named Amazon’s Best Science Book of the Year and an MIT Technology Review top pick.

Christian’s acclaimed bibliography includes The Most Human Human, a Wall Street Journal bestseller dissecting artificial intelligence through his experience in Turing test competitions, and The Alignment Problem, a finalist for the Los Angeles Times Book Prize that investigates AI ethics. His writing has appeared in The New Yorker, The Atlantic, and Wired, and he has been featured on The Daily Show and Radiolab. A frequent speaker at institutions like Google, Yale, and the London School of Economics, Christian’s books have been translated into 19 languages, with The Alignment Problem hailed by The New York Times as essential reading on artificial intelligence.

Common FAQs of Algorithms to Live By

What is Algorithms to Live By about?

Algorithms to Live By by Brian Christian and Tom Griffiths explores how computer science algorithms can optimize everyday decision-making. It covers concepts like optimal stopping (the 37% rule), sorting vs. searching trade-offs, and caching, applying them to challenges like hiring, organizing tasks, or managing time. The book bridges computational principles with human behavior, offering actionable strategies for balancing efficiency and rationality.

Who should read Algorithms to Live By?

This book suits tech enthusiasts, decision-makers, and fans of behavioral psychology. It’s ideal for readers seeking frameworks to tackle complex choices, from career moves to daily prioritization. Those interested in interdisciplinary insights—melding computer science, philosophy, and cognitive science—will find it particularly engaging.

Is Algorithms to Live By worth reading?

Yes. A #1 Audible bestseller and Amazon “Best Science Book,” it combines rigorous research with relatable examples. Critics praise its blend of theory and practicality, making abstract algorithms accessible for real-world problems like scheduling or relationship decisions.

What is the 37% rule in Algorithms to Live By?

The 37% rule, from optimal stopping theory, suggests spending 37% of your time exploring options (e.g., job candidates, apartments) before committing to the next best option. This balances exploration and exploitation, minimizing regret in hiring, dating, or financial decisions.

How does Algorithms to Live By apply to everyday life?

It offers strategies like:

  • Sorting vs. searching: Organize emails once to reduce future search time.
  • Caching: Prioritize frequently used items (e.g., kitchen tools) for efficiency.
  • Randomness: Use random exploration to escape decision paralysis.
What are key takeaways from Algorithms to Live By?
  • Trade-offs: Balance perfectionism with “good enough” outcomes.
  • Computational kindness: Simplify others’ decisions by constraining choices.
  • Relaxation: Accept approximate solutions for intractable problems.
What famous quotes are in Algorithms to Live By?

“Looking through the lens of computer science can teach us about the nature of the human mind... and how to live” encapsulates the book’s goal of merging algorithmic logic with human experience.

What are criticisms of Algorithms to Live By?

Some argue real-life decisions involve emotions and ambiguity that rigid algorithms can’t capture. The 37% rule, for instance, may oversimplify nuanced scenarios like career changes.

How does Algorithms to Live By compare to Thinking, Fast and Slow?

While Daniel Kahneman’s book focuses on cognitive biases, Algorithms to Live By emphasizes structured problem-solving from computer science. Both explore decision-making but differ in framing—psychological heuristics vs. computational optimization.

What is Brian Christian’s background?

Brian Christian holds degrees in computer science, philosophy, and poetry. His interdisciplinary approach informs works like The Most Human Human and The Alignment Problem, blending technical rigor with existential inquiry.

Why is Algorithms to Live By relevant in 2025?

As AI and automation grow, its lessons on algorithmic thinking help navigate tech-driven decisions—from ethical AI design to personal time management in a distracted world.

What lesser-known concepts does Algorithms to Live By explore?
  • Scheduling with deadlines: Use “earliest due date” prioritization.
  • Bayesian inference: Update beliefs systematically with new data.
  • Exponential backoff: Manage conflicts or retries in communication.
