Development Phases

A new brain is like a child. Curious about everything.

Child (0-10 sessions)

The critical period. Low thresholds, high absorption. Everything is new, everything is stored. The brain asks many questions, absorbs rapidly, forms initial connections. Like a child learning to speak — every input matters.

Youth (10-50 sessions)

Aggressive pruning begins. The brain has enough data to know what matters and what doesn't. Weak connections get cut. Specialization starts — the brain develops expertise in your specific domain. Schemas begin to form.

Adult (50-1000 sessions)

Stable, fast, deep. The brain has rich schemas, strong patterns, and efficient retrieval. It anticipates your needs. Context generation is precise. New information is evaluated against existing knowledge — contradictions are flagged, confirmations strengthen edges.

Wise (1000+ sessions)

A vast knowledge network. Prediction is nearly perfect. The brain has seen enough patterns to understand not just what you do, but why you do it. Cross-domain connections are rich and unexpected. The brain truly knows you.

Run brainbase stats to see your session count and whether you're still in the critical period (under 20 sessions).
