For the first time since the late 1800s, a generation is measurably less intelligent than the one before it, and the culprit is the very technology being pushed into every classroom across America.
Story Overview
- Neuroscientist testifies to US Senate that Gen Z shows lower cognitive abilities than Millennials, reversing 150 years of generational improvement
- Global data from 80 countries links excessive school screen time to two-thirds standard deviation drop in performance
- Declines documented across attention span, memory, reading comprehension, math skills, problem-solving, and IQ
- Educational institutions lowering standards and adjusting tests to accommodate shortened attention spans
Senate Testimony Reveals Unprecedented Cognitive Decline
Dr. Jared Cooney Horvath, a neuroscientist with expertise in education, delivered sobering testimony to the US Senate Committee on Commerce, Science, and Transportation in 2026. His research demonstrates that Gen Z, born from the mid-1990s to early 2010s, exhibits measurably lower cognitive capabilities than their Millennial parents across multiple domains. This reversal breaks a 150-year pattern of each generation outperforming the previous one in cognitive metrics tracked since the late 1800s. Horvath’s findings stem from comprehensive data spanning 80 countries, providing a global perspective on this alarming trend.

EdTech Overreliance Identified as Primary Cause
The cognitive decline correlates directly with the widespread introduction of screens and digital technology in educational settings around 2010. Horvath’s research reveals that students using devices five or more hours daily in schools experience performance drops equivalent to two-thirds of a standard deviation. This isn’t about teaching methods but rather the medium of instruction itself. When technology serves as the primary learning platform instead of supplementing traditional instruction, students fail to develop deep thinking capabilities essential for memory retention, complex problem-solving, and sustained attention. Denmark noticed concentration issues from screen-swiping behavior and responded by returning books to classrooms.
Educational Standards Lowered to Accommodate Deficits
Rather than addressing the root cause, educational institutions have chosen to accommodate declining abilities. Elite universities have eased curriculum requirements specifically for Gen Z students. Standardized tests have been adjusted to account for shorter attention spans. This response treats symptoms while ignoring the disease eating away at our children’s intellectual development. Harvard studies document phonological gaps appearing as early as 18 months in children with insufficient reading exposure. The once-celebrated Flynn Effect, which documented rising IQ scores throughout the 20th century, has reversed. Parents who remember memorizing multiplication tables now watch their children struggle with basic arithmetic while their faces remain glued to screens.

Broader Implications for American Competitiveness
The economic and national security implications are staggering. Weakened literacy and numeracy skills ripple through STEM fields and social studies, undermining America’s competitive edge in innovation and technology. Horvath characterizes this situation as a “societal emergency” requiring immediate policy reforms. The workforce productivity impacts will compound as Gen Z enters positions of greater responsibility with diminished cognitive tools. Meanwhile, doomscrolling and fragmented information consumption erode the capacity for sustained discourse necessary for democratic participation.
Horvath emphasizes his position is not anti-technology but advocates for balanced implementation that aligns with how human brains actually learn. His testimony calls for adjusting EdTech usage to support rather than replace face-to-face instruction and deep reading. Some defend Gen Z’s strengths in pattern recognition and emotional intelligence, questioning whether traditional IQ measures capture the right capabilities. However, the data remains clear: fundamental cognitive abilities essential for complex reasoning have declined.
