U.S. public schools have spent an astounding $30 billion on laptops and tablets in 2024, which is ten times the expenditure on traditional textbooks. This investment was aimed at enhancing educational accessibility and providing students with a wealth of learning resources. However, the anticipated outcomes have not materialized, as reports suggest a decline in essential cognitive skills among Generation Z, marking a stark contrast to the capabilities of previous generations.

Neuroscientist Jared Cooney Horvath testified highlighting a troubling trend: Gen Z is the first generation in modern history to perform worse on standardized tests than their predecessors. This is alarming given that similar patterns have been observed across over 80 countries, demonstrating a global decline in cognitive abilities such as IQ, executive functioning, and creativity. The descent in educational outcomes appears to correlate with the increased presence of digital devices in classrooms, particularly from around 2010 onwards.

The widespread use of technological devices was expected to open doors to new learning possibilities, yet the reality presents a cautionary tale about over-reliance on digital technology in education. This situation raises critical questions about how schools can better integrate technology to support rather than hinder cognitive development in students. The implications of these findings are significant, prompting educators and policymakers to reevaluate their strategies and consider more balanced approaches to leveraging technology in learning environments.
