Point System Model of Skill

The point system model is a deliberately rough quantification CF uses to reason about prerequisites. Each skill is scored 0–100, where 100 is the highest skill anyone currently has and 0 is total ignorance. The key rule: your skill at a topic cannot meaningfully exceed your skill at the knowledge it builds on. If your prerequisites sit at 40, your skill at the dependent topic (e.g. CF philosophy) is approximately capped at 40.

The model’s main payoff is about gaps, which drives CF’s skill-gap management. The further your skill lags behind its prerequisites, the easier and faster improvement is; pushing near the ceiling gets hard and error-prone. So with prerequisites at 40, reaching 15 is quick, but closing the last few points is costly. CF’s prescription is therefore counterintuitive: deliberately keep your higher-level skill lagging (a gap of ~25 at low scores, narrowing as you climb) rather than maxing it out, because learning a given point cheaply beats learning the same point expensively.

CF stresses the model is only an approximation. Prerequisites actually come in many layers, with smaller losses between adjacent ones; different sub-skills score separately; and multiple build-up paths exist, allowing workarounds that skip a specific prerequisite. The model also explains creating new knowledge: near the ceiling (90+), inventing fresh ideas (scoring “past 100”) becomes comparably hard to mastering the last existing knowledge, whereas at low scores it is far harder. This grounds CF’s advice to cycle between prerequisites and target topic rather than finishing one before the next.
