Neuroscientist Jared Cooney Horvath warns that Generation Z’s cognitive capabilities are declining, attributing this trend to excessive screen time and technology use in educational settings.
Neuroscientist Jared Cooney Horvath has raised significant concerns regarding the cognitive capabilities of Generation Z, suggesting that this cohort is less cognitively adept than previous generations. During a recent testimony before the U.S. Senate Committee on Commerce, Science, and Transportation, Horvath presented alarming data indicating a decline in cognitive performance among Generation Z, which he attributes to increased screen time and technology use in educational environments.
Horvath’s testimony comes at a time when schools across the United States have heavily invested in technology, spending over $30 billion in 2024 alone on laptops and tablets for educational purposes. Despite this substantial investment, Horvath argues that the outcomes have been detrimental to student learning. He pointed out that Generation Z is the first generation in modern history to score lower on standardized tests compared to their predecessors.
Referencing data from the Program for International Student Assessment, Horvath highlighted a global decline in test scores among 15-year-olds, correlating increased screen time with poorer academic performance. This trend has raised concerns among educators and psychologists about the effectiveness of technology in enhancing educational outcomes.
The historical context of educational technology reveals a troubling trajectory. Initiatives such as the Maine Learning Technology Initiative, which began in 2002 under then-Governor Angus King, aimed to integrate technology into classrooms by distributing thousands of Apple laptops to middle school students. By 2016, the initiative had expanded significantly, with 66,000 devices in circulation. However, reports indicated that Maine’s public school test scores stagnated over the years, prompting former Governor Paul LePage to label the initiative a “massive failure.”
This stark contrast between the initial vision of educational technology and its current implications raises critical questions about its deployment in classrooms. Horvath noted that while technology was intended to empower students with knowledge, it has inadvertently contributed to cognitive atrophy. He emphasized the need to align educational tools with how human learning functions, asserting that unchecked digital expansion has weakened learning outcomes rather than enhancing them.
In his analysis, Horvath pointed to research indicating that students often engage in off-task activities on their computers. One study revealed that university students spent nearly two-thirds of their time on non-educational tasks. This dispersion of attention, exacerbated by the design of various applications, has led to decreased memory retention and increased error rates in academic work. Horvath remarked, “Learning is effortful, difficult, and oftentimes uncomfortable. But it’s the friction that makes learning deep and transferable into the future.”
Concerns about the impact of technology on learning are echoed by Jean Twenge, a psychology professor at San Diego State University. Twenge noted that many apps are designed to be addictive, further detracting from students’ ability to focus on their studies. With social media and gaming applications vying for users’ attention, the implications for academic performance and mental health are significant.
As the conversation around technology’s role in education continues, some states have begun to take action. As of August 2025, 17 states have implemented restrictions on cellphone use during instructional time, reflecting a growing recognition of the need to mitigate distractions in the classroom. However, enforcement of these policies has varied, and many educators are still grappling with the challenges posed by digital devices in learning environments.
Horvath advocates for a comprehensive approach to address these issues at the policy level. He suggests that Congress could impose efficacy standards to evaluate educational technology and establish regulations on data tracking and behavior profiling of minors. Such measures could help ensure that technology serves as a beneficial educational tool rather than a hindrance.
The implications of declining cognitive skills among Generation Z extend beyond educational performance; they raise concerns about the future workforce and society’s ability to tackle complex challenges. Horvath warned, “We’re facing challenges more complex and far-reaching than any in human history—from overpopulation to evolving diseases to moral drift. Now, more than ever, we need a generation able to grapple with nuance, hold multiple truths in tension, and creatively tackle problems that are stumping the greatest adult minds of today.”
As the dialogue surrounding educational technology evolves, it is crucial for policymakers, educators, and the public to consider the long-term ramifications of current practices. Horvath’s assertion that today’s youth are victims of a failed pedagogical experiment underscores the urgent need for a reassessment of how technology is integrated into the learning process, according to Source Name.
