Upon detecting a fatal infection using chemical cues, ants puncture the cuticle of sick brood and inject antimicrobial poison that disrupts the pathogen's life cycle and prevents it from reproducing, thus protecting the colony from disease.

Relative value perception, a basic tenant of Behavioural Economics, is demonstrated in an insect, and further shown to be driven by cognitive processes and induced by private and social information.

Ants are subjected to logarithmic value perception, causing deviation from pure rationality as described by classical economics decision theories.
