Evolutionary Mismatch Theory
Traits suited to earlier environments may function differently in rapidly changing conditions.
The Mechanism: Evolutionary mismatch occurs when a trait shaped in one environment interacts with a substantially changed environment. The concept can generate hypotheses, but specific claims require evidence about both past and present conditions.
The Philosophical Pivot: Calling a behavior ancestral can make modern problems seem inevitable. Yet humans are adaptable, cultures change, and environments are not a single timeless modern world.
The Horizon: Mismatch frameworks can help explain why some incentives or abundant resources produce unexpected effects. They should not reduce every difficulty to a Pleistocene brain or excuse institutions from change.
A mismatch is relational: altering the environment can matter as much as altering the individual. Public design can reduce friction without demanding that people overcome every obstacle alone.
The past influences us, but it does not dictate what we can build next.
A trait is not maladaptive in isolation; it is mismatched with a particular world.
What part of my environment might be creating a problem I have been taught to treat as a personal failure?
