The Conch Paradox

Our greatest strengths often contain the seeds of our greatest vulnerabilities. The shell that protects also constrains.
When their unborn son was diagnosed with a life-threatening heart condition, Rendell de Kort's family was thrust from Aruba into the medical complexity of Rotterdam. Saving his life meant surrendering control of it entirely.
That confrontation with vulnerability revealed a pattern hiding in plain sight: in island economies optimized for shocks they already know, in institutions built to protect what no longer exists, and in a million-year-old conch shell whose perfect armor now threatens the species' survival.
Drawing on development economics, marine biology, and personal narrative, The Conch Paradox argues that resilience is never neutral. Every protective adaptation simultaneously creates new vulnerability. Every strength optimized for one environment becomes a liability when that environment shifts. This is not a flaw in the system. It is the system.
What shells have you built? And are they still protecting you?
Rendell de Kort is a development economist and PhD researcher at Vrije Universiteit Amsterdam, specializing in disaster risk financing and economic resilience in small island developing states. Born and raised in Aruba, he lives there with his family.
