Path dependence means today's feasible moves depend on yesterday's irreversible steps. It intersects feedback delays, systems archetypes, first principles, modularity, and the Iceberg Model—because the visible promotion is an event; the corridor is structure.
1. History Is a Ratcheting Constraint
Path dependence means today's optimal choice set is carved by yesterday's commitments: credentials, geography, vesting cliffs, tax basis, reputation, and the quiet shame of sunk costs. You are not "free" each morning; you inherit a graph. Wealth strategy that ignores the path treats life like a menu instead of a trajectory.
Link the idea to feedback delays: early path choices look cheap because the bill arrives years later, often as missed optionality rather than as an invoice.
"The cheapest door is often the most expensive hallway."
2. Switching Costs Are Balance-Sheet Items
Career capital, client concentration, and specialized tooling create exit taxes. So do golden handcuffs, non-competes, and lifestyle baselines defended by balancing loops. Path dependence is not fatalism; it is pricing the exit tax honestly before you sign.
3. Archetypes of Lock-In
Systems archetypes like "success to the successful" explain how early wins fund later constraints: the same loop that built the castle pays for the moat you now must defend. Naming the archetype keeps regret from masquerading as strategy.
What cannot unwind without cost? Degrees, partnerships, equity grants, real estate, children, debt covenants.
Months of runway, legal fees, tax hits, retraining—put numbers beside each.
Skills and income streams that pay even if the main identity pivots—see modular systems.
Marriage, acquisition, regulation—paths fork. Update the map or inherit someone else's default.
4. First Principles on Forks
When considering a pivot, run first principles on what must remain true regardless of brand or title. Often the path-dependent asset is not the job—it is the cashflow shape and risk exposure. Refactoring those without changing business cards is still a fork.
5. Icebergs Under Career Narratives
Promotions and titles are events; path dependence lives in structure—who owns your time, who owns your distribution, who can change the rules. Pair this chapter with the Iceberg Model so you stop debating the foam while the hallway lengthens underwater.
Build the lattice, not the legend.
