Engelbart Lenses — Ways to View the World

Engelbart Lenses

Doug Engelbart didn't just invent the mouse. He invented a way of thinking about how humans and tools co-evolve. These lenses draw from his work and extend it — each one a different way to look at the same reality.

Hi


1. The Tool Lens

Every object is an interface between intention and outcome. A pencil augments memory. A calendar augments foresight. What tool is missing from this situation?

2. The Bootstrapping Lens

Improving the process of improvement. Not "how do we solve this problem?" but "how do we get better at solving problems like this?" The meta-game always outweighs the object-level game.

3. The Collective IQ Lens

Intelligence is not individual — it's networked. The unit of analysis is the group, not the person. How does the knowledge flow? Where are the bottlenecks? What would double the group's effective IQ?

4. The Co-Evolution Lens

Humans shape tools. Tools shape humans back. You can't understand either in isolation. Every new capability changes what people attempt, which changes what tools they need.

5. The Augmentation Lens

Not automation (replacing humans) but augmentation (extending what humans can do). For any task: what part requires human judgment? What part is mechanical overhead? Strip the overhead.

6. The ABC Model Lens

Engelbart's three levels: A-level (doing the work), B-level (improving how we do the work), C-level (improving how we improve). Most organizations are trapped at A-level. The leverage is in B and C.

7. The Knowledge Repository Lens

Every conversation, decision, and discovery is potential shared knowledge — if captured and made findable. What's the half-life of institutional knowledge here? What walks out the door when someone leaves?

8. The High-Performance Team Lens

Small groups with shared context, rapid iteration, and tight feedback loops outperform large groups with none of those. What would it take to make this team a high-performance knowledge team?

9. The Paradigm Map Lens

Every field has an implicit paradigm that constrains what questions are even askable. What paradigm is operating here? What would the next paradigm look like? (Engelbart himself operated outside the prevailing paradigm of computing.)

10. The NKMA Lens

Naming, Knowledge, Methodology, Artifacts — Engelbart's four augmentation systems. When something isn't working, which system is broken? Do we lack the right words (naming)? The right understanding (knowledge)? The right process (methodology)? The right tools (artifacts)?

11. The Unfinished Revolution Lens

Engelbart believed his vision was only 5% realized at the time of his death. What remains unfinished? What capabilities did he describe in 1962 that still don't exist? The gap between vision and reality is where the real work is.

12. The Purple Number Lens

Every idea should be addressable. Every paragraph, every claim, every piece of evidence — individually linkable, quotable, and composable. If you can't point to it precisely, you can't build on it.
