Thinking, Fast and Slow — heuristics, fluency, and dual-process judgment
Part I — Two Systems
Extract. Capture. Transform. Load.
A knowledge graph that compounds.
Cognitive ETL is a thinking machine: each source is preserved as raw capture, compressed into atoms, and pushed into public artifacts so reading becomes a visible creative practice instead of private accumulation.

Fast cognition optimizes for coherent stories before careful accuracy checks
Fast judgment produces an immediately usable interpretation by assembling a plausible story from partial cues.
“Paraphrase: quick thought builds the most coherent account it can from the evidence at hand.”
Cognitive fluency is often misread as evidence of truth
Ideas that are easier to process can feel more credible even when the underlying evidence is weak.
“Paraphrase: ease of processing can masquerade as evidence.”
Counterfactual reasoning is what makes causal models useful for explanation and choice
A causal model becomes decision-relevant when it can compare the observed world with plausible alternative worlds.
“Paraphrase: causal understanding reaches its highest utility when it can answer what would have happened otherwise.”

Cognitive fluency often feels like truth before it deserves trust
Ease of processing acts like a proxy for correctness. The mind confuses familiarity and fluency with reliability.

Counterfactual questions are what turn causal models into decision tools
Interventions tell us what follows from doing something. Counterfactuals go further by comparing the world that happened with the world that could have happened.

System 1 quickly produces coherent judgments from sparse evidence
The fast mind is optimized for immediate coherence, not careful audit. It fills gaps quickly and treats the resulting story as if it were well-grounded.

Environment diversity is the real supervision signal
Multiple environments make causal learning possible because changes reveal which features are invariant and which are spurious.
