Successful Companies Go Blind
Ian Reppel draws a brilliant analogy between successful companies and blind Mexican cavefish to explain "competence blindness." He argues that sustained success can create an environment where fundamental engineering competence becomes a vestigial trait, suppressed by internal comfort and a lack of external pressure. This insightful piece resonates deeply on HN by articulating the frustrating reality many skilled professionals face in established organizations, where sight is lost but the cave remains "geologically stable."
The Lowdown
This article introduces the concept of "competence blindness" in successful companies, using the compelling analogy of the Mexican cavefish. Just as the cavefish loses its sight when adapted to a dark environment, companies can lose their core competencies, not by deliberate choice, but through systemic adaptation to continued success. The piece explores how this phenomenon manifests and its implications for both organizations and their employees.
- The Cavefish Analogy: The Mexican cavefish, Astyanax mexicanus, exists in two forms: one sighted in rivers and one blind in caves. Despite identical genomes, cave-dwelling fish redirect energy from developing eyes to traits better suited for their dark environment, like enhanced olfaction. If hatched in a river, they would see.
- Competence Blindness Defined: Companies that forget their path to success develop a similar blindness. They stop recognizing competence because the internal environment no longer expresses or rewards it, favoring comfort with existing inefficiencies. This differs from failing due to clinging to old markets; these firms can survive for decades.
- Internal Decay Amidst External Success: Rapid growth leads to hiring that lowers quality, fostering a workforce comfortable with internal "mess." While external metrics (brand, margins) remain strong, internal infrastructure decays, with fragile deployments and outdated documentation. Careful engineering becomes a vestigial trait, unrewarded by the system.
- Resistance to Outside Viewpoints: New hires who bring external "sight" find their suggestions dismissed as over-engineered or an attack on existing practices, leading to a form of internal "apoptosis" of their proactive problem-solving.
- Ineffective "Centres of Excellence": Companies often respond by creating "centres of excellence." These typically stifle intrinsic motivation and centralize control, paradoxically suppressing the very excellence they claim to cultivate.
- Geological Stability and Talent Attrition: When market barriers to entry are high, incumbents can tolerate inefficiency without competitive pressure, allowing the "cave" to remain stable. Sighted engineers are still attracted but either leave after realizing their skills are regressing or adapt to the "cave rules," losing their own sight over time.
- Staying as Apoptosis: The article reinterprets the act of staying in a dysfunctional company not just as acquiescence, but as a form of adaptation where one's skills and perspective atrophy, akin to cellular apoptosis.
- Hope for "Surface Populations": Like the cavefish retaining its eye genes, companies' fundamental capabilities aren't necessarily lost. A change in environment (a new "water") can switch sight back on, implying that individuals can regain their vision by moving to different contexts.
The article powerfully illustrates how long-term success can paradoxically foster an environment where fundamental competence atrophies. Through the cavefish metaphor, it explains why companies might internally degrade while appearing robust externally, and how this process affects the talent within, often leading to a loss of "sight" that is both gradual and insidious.
