Prevailing explanations—such as the Great Filter, self-destruction scenarios, and the Dark Forest
hypothesis—presuppose that advanced intelligences share fundamental cognitive and behavioral traits
with humans. This paper introduces the Cognitive Non-Overlap Hypothesis, which posits that
sufficiently advanced intelligences may evolve cognitive architectures fundamentally
incommensurable with human frameworks. Under this hypothesis, extraterrestrial intelligences could
pervade the universe yet remain unrecognizable as "civilizations" by human standards. Technological
civilization emerges as a transient phase; intelligence may subsequently transcend detectable forms,
rendering cosmic silence a consequence of human cognitive limitations rather than absence of other
minds. The hypothesis is formalized through a multi-stage evolutionary model and a cognitive overlap
function, offering a novel interpretive lens for SETI and astrobiology.
