Why Gen-Z’s IQ May Be Declining — And What It Means for the Future

<strong>For the first time in modern history, human intelligence may be going backward.</strong>

According to a report presented by neuroscientist <strong>Dr. Jared Cooney Horvath</strong>, Generation Z may be experiencing lower IQ levels than Millennials — a shocking reversal of the century-long trend known as the <strong>Flynn Effect</strong>.

These findings were discussed during a <strong>2026 U.S. Senate Committee hearing</strong>, igniting urgent conversations about technology, education, and the future of human cognition.

Since around 2010, screens and educational technology have replaced deep reading, discussion, and long-form thinking. While digital tools offer convenience, <a href="/article/what-jobs-will-completely-disappear-by-2030-experts-warn" title="What Jobs Will Completely Disappear by 2030 — Experts Warn" class="internal-link">experts warn</a> they may be weakening the brain’s natural learning systems.

Human cognition evolved through storytelling, face-to-face interaction, repetition, and reflection — not rapid scrolling and bullet-point summaries.

Gen-Z has grown up surrounded by short-form videos, constant notifications, and digital multitasking. Neuroscience shows this environment trains the brain for speed rather than depth, making sustained focus increasingly difficult.

This loss of deep attention directly impacts memory, reading comprehension, problem-solving, and <a href="/article/how-to-develop-emotional-intelligence-your-roadmap-to-mastering-your-inner-world" title="How to Develop Emotional Intelligence: Your Roadmap to Mastering Your Inner World" class="internal-link">emotional intelligence</a>.

This is not just a Western issue. Declines in attention, memory, reading, and mathematics have been documented in <strong>over 80 countries</strong>, suggesting a global transformation in how intelligence develops <a href="/article/holistic-approaches-to-mental-wellness-in-the-digital-age" title="Holistic approaches to mental wellness in the digital age" class="internal-link">in the digital age</a>.

Ironically, Gen-Z spends more time in formal education than any previous generation. Yet cognitive performance has plateaued — or even declined.

This reveals a critical truth: <strong>more education does not automatically mean better learning</strong> — especially when technology replaces deep thinking instead of supporting it.

Experts believe this decline is not permanent. By redesigning education to prioritize deep reading, human connection, critical thinking, and meaningful problem-solving, societies can strengthen cognitive development.

Technology must shift from being a replacement for thinking to a tool that enhances it.

The reported reversal of the Flynn Effect is a warning — but also an opportunity. If we act now, we can reshape education to build smarter, more focused, and more resilient future generations.
