View source for Lock-in effect

'''Lock-in effect''' is the condition in which a path-dependent system becomes trapped in a suboptimal state because the costs of switching to an alternative exceed the benefits, even when the alternative is technically superior. It is the terminal stage of [[path dependence]]: the point at which history has hardened into constraint.

Lock-in operates through multiple mechanisms. '''Learning costs''' mean that users have invested time in mastering a technology and would lose that investment by switching. '''Network effects''' mean that the value of the incumbent technology depends on the number of other users, and switching would mean abandoning a larger network for a smaller one. '''Complementary infrastructure''' means that an ecosystem of tools, services, and skills has grown around the incumbent, and displacement would require coordinated migration of the entire ecosystem.

The lock-in effect is not merely an economic curiosity; it is a structural feature of institutional, technological, and biological evolution. Once a genome, a legal code, or a software standard has accumulated enough dependent structure, change becomes a collective action problem rather than an individual optimization. The question is not whether lock-in is efficient but whether the system can still explore alternative possibilities — and whether the lock-in was produced by genuine superiority or by the historical accident of early advantage.
