nonreplicable

Impossible to reproduce

Nonreplicable describes something that cannot be reproduced or duplicated, most commonly used in scientific contexts where an experiment or study yields results that other researchers are unable to repeat.

A nonreplicable finding is troubling in science because replication is a cornerstone of the scientific method—if results can't be independently verified, their validity comes into question.

The study's nonreplicable results sparked concerns about the original methodology.
