This event highlights a potential long-term decline in cognitive capabilities across a significant demographic, Generation Z, which could impact future workforce productivity and innovation.

Neuroscientist Jared Cooney Horvath has revealed that Generation Z, born between 1997 and 2010, is the first generation in modern history to exhibit lower scores on standardized academic tests compared to their predecessors.
