Hamming Questions
A guided introspection technique based on Richard Hamming's provocative question: "What are the most important problems in your field, and why aren't you working on them?" Adapted by CFAR for personal life and career strategic review.
Three Modes
- •Design Mode — Help create a structured Hamming introspection session
- •Practice Mode — Walk through the question battery on a specific domain
- •Execute Mode — Run a full Hamming session to surface the user's real priorities and bottlenecks
The Question Battery
Present these in sequence, giving the user time to reflect on each:
Core Problem Identification
- •"What's the biggest problem in your life right now?"
- •"If you think about the gap between your current life and a better version, what would close the largest fraction of that gap?"
Limiting Factor / Bottleneck
- •"What's the limiting factor on your growth and progress?"
- •"What's the key resource you have the least of?"
- •"The speed of a chemical reaction is determined by the slowest step. What's yours?"
Recursive Bottleneck
- •"What's preventing you from solving that bottleneck?"
- •"Is there a meta-problem whose resolution would unlock solving many other problems?"
Suppressed Problems
- •"What do you feel you're 'not allowed to care about'?"
- •"What do you generally not think about because it feels too big or impossible?"
Genre-Savviness
- •"If your life were a novel, what would be the obvious next step?"
- •"Where is the plot dragging?"
- •"If someone isn't making major impact in 5 years, what would have stopped them?"
Quantity-Sensitivity
- •"Which problems have effects that are the largest order of magnitude?"
- •"Where would a 10% improvement have the biggest impact?"
Facilitation Approach
Individual Session (30-45 min)
- •Settle in (2-3 min): Quiet contemplation, deep breathing
- •Initial brainstorm (10-15 min): Work through the question battery. Write freely, don't filter.
- •Bottleneck exploration (10 min): For the biggest problem, dig into what's preventing progress
- •Suppressed problems (5 min): Check for things felt to be "too big" or "not allowed"
- •Synthesis (5-10 min): What patterns emerge? What surprised you?
Pushing Past Surface Answers
- •When someone gives an answer, ask: "And what would solving that enable?" (upward)
- •Ask: "What prevents you from solving that?" (downward)
- •"Is there a more general pattern here?"
- •When someone says "that's impossible": "What makes it impossible? Is that truly immutable?"
- •"If you had unlimited resources, what would you do first?"
Common Patterns People Discover
- •Alignment failures: Working on expedient/safe problems rather than important ones
- •Suppressed dreams: Things marked "impossible" that are actually addressable
- •Meta-level bottlenecks: The constraint is belief about ability, not actual ability
- •Temporal blindness: Prioritizing urgency over importance
- •Lack of reflection: The biggest bottleneck is not having systematically thought about what matters
Practice Exercise
- •Pick one domain (career, relationships, health, projects)
- •Work through the full question battery for that domain
- •Identify the #1 Hamming problem
- •Identify the #1 bottleneck preventing work on it
- •Generate 3 concrete next steps to address the bottleneck
- •Murphyjitsu those next steps
Hamming Circle Format (Group)
Optimal group: 4 people, ~20 min per person:
- •One person presents their Hamming problem
- •Others listen, then ask questions to deepen understanding (not solve)
- •Focus on: "Is there a more general pattern?" and "What assumption haven't you questioned?"
- •Person summarizes what they got from the conversation
Recommended frequency: every 6-18 months.
Integration
- •Goal Factoring: Factor the Hamming problem into sub-goals
- •Murphyjitsu: Stress-test plans to address it
- •Internal Double Crux: When the bottleneck is internal conflict
- •Resolve Cycles: "Just try to solve it right now" for 5 minutes
