The ancient algorithm that still works

Your brain is running 200,000-year-old software. Yet it navigates smartphones, elevators, and light switches effortlessly.

How? Inductive reasoning — the ability to see ONE example and form a general rule.

A caveman sees someone flip a switch, lights come on. That's enough. The brain immediately forms: "switches control lights."

This same pattern-matching let our ancestors learn from single experiences:

One Example Was Enough
🫐 Red berry → sick → avoid red berries
🌿 Rustling grass → predator → run next time
🔥 Touch fire → pain → fire is dangerous
💧 River here yesterday → river here today
The superpower: We don't need 1,000 examples. We generalize from minimal data. This is why humans adapt to new technology instantly — we extract the pattern and apply it everywhere.
