Neuroscientist Jared Cooney Horvath has raised concerns that Generation Z is less cognitively capable than previous generations, attributing this trend to increased screen time and technology use in educational settings.
In a recent testimony before the U.S. Senate Committee on Commerce, Science, and Transportation, neuroscientist Jared Cooney Horvath presented alarming data suggesting that Generation Z is experiencing a decline in cognitive capability compared to their predecessors. This assertion comes as schools across the United States have invested heavily in technology, with more than $30 billion spent in 2024 alone on laptops and tablets for educational purposes. Yet, despite this unprecedented access to technology, Horvath argues that the outcomes have been detrimental to student learning.
Horvath’s testimony highlighted that Generation Z is the first generation in modern history to score lower on standardized tests than the previous generation. He referenced data from the Program for International Student Assessment, which indicated a decline in test scores among 15-year-olds worldwide, correlating increased screen time with poorer academic performance. This trend has raised concerns among educators and psychologists regarding the effectiveness of technology in enhancing educational environments.
Historical Context of Educational Technology
The roots of this issue can be traced back to initiatives like the Maine Learning Technology Initiative, which began in 2002 under then-Governor Angus King. This program aimed to integrate technology into the classroom 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 had stagnated over the years, leading former Governor Paul LePage to label the initiative a “massive failure.”
The 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.
Impacts of Technology on Learning
In his analysis, Horvath pointed to research indicating that students often engage in off-task activities on their computers, with one study showing 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 are echoed by Jean Twenge, a psychology professor at San Diego State University, who 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.
Legal and Policy Responses
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.
Looking Ahead
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.
