A recent scientific claim suggests that Generation Z (typically defined as those born between 1997 and 2010) may be less intelligent than Millennials and earlier generations has ignited intense debate across social media, academic circles and newsrooms worldwide because of the long-held assumption that intelligence steadily increases over time and raises uncomfortable questions about the modern world now Gen Z is growing up in.
According to the neuroscientist, Dr. Jared Cooney Horvath, academical performance, intelligence test scores, problem-solving, reasoning, and concentration appear to be declining among younger generations. This apparently contradicts the so-called Flynn Effect, a phenomenon that showed IQ scores rising consistently throughout the 20th century. For the first time in decades, the data suggests that progress may be moving backward.
“They’re the first generation in modern history to score lower on standardized academic tests than the one before it,” Dr. Horvath said, pointing to over-reliance on technology as a key contributing factor.
“More than half of the time a teenager is awake, half of it is spent staring at a screen,” he said. “Humans are biologically programmed to learn from other humans and from deep study, not flipping through screens for bullet point summaries.”
Unlike Millennials, Gen Z has grown up entirely immersed in smartphones, social media, and short-form content. While critics often blame Gen Z for overly relying on technology, there is an important question that is frequently overlooked: Did Gen Z truly have the opportunity to grow up in a healthy and balanced environment or were they simply born into rapid technological change without meaningful guidance?
When the technology was new to Gen Z, it was widely promoted by scientists, developers and educators, preaching how it improved access to information and new ways of learning. Today, when technology is becoming extremely overwhelming, those who have been using it get heavily criticized over weakened attention spans, deep reading habits, and critical thinking skills.
While it is true that Gen Z has experienced the “side effects” of prolonged digital exposure, it is also important to acknowledge the broader context. Many young people have been pushed further into digital spaces partly because real-world environments have become increasingly stressful and demanding. For some, technology became a coping mechanism rather than a choice.
With digital overexposure at the center of the debate, Horvath also shared that Gen Zs are “overconfident about how smart they are” and that “the smarter the people think they are, the dumber they actually are.”
The scientists who support this claim express that they themselevs performed at higher cognitive levels when they were at Gen Z’s age. They have been blunt about how sad it is to have such lower IQ scores. This perspective invites a critical reflection: where was this concern when earlier generations upheld beliefs rooted in superstition, discrimination, sexism, misogyny, extremism, and systemic injustice? It is safe to say that many of those harmful ideologies continue to shape lives today.
It is evident that through technology or not, the younger generations started the trend of embracing scientific reasoning, empathy, and social awareness. While Gen Z is frequently labeled as “less intelligent or dumb” it is also the generation that has challenged injustice, questioned harmful norms, and stood together despite widespread backlash.
Technology has undoubtedly affected young people, often negatively, especially with the rapid rise of AI. However, rather than accusing the youth, should responsibility not lie with those had the authority, resources ad foresight to guide its use more effectively in the first place? If cognitive abilities and intelligence among older generations were indeed superior, why was there so little intervention when children were the first to being immersed in digital environments? Early guidance and mindful restrictions could have mitigated many of these challenges.
Labeling an entire generation as “less intelligent or dumb” is not only misleading but harmful. While older generations grappled with socio-cultural issues that they themselves invented, younger generations are fighting socio-economic inequality, pandemic-related disruptions, mental health challenges, and educational gaps; the debris of what cognitively capable generations had to offer.
What’s clear is that this debate goes far beyond test scores. It is true that these claims though being controversial do encourage society to confront how technology, education based on technology and lifestyle choices are influencing human intelligence and how progress should be measured differently in the 21st century.
But what is also true is, these claims should not diminish the progress younger generations have made in terms of humanity, empathy, emotional intelligence and social awareness. Harmful ideologies such as sexism and abusive behavior are heavily challenged by young people today rather than normalized. Even when such behaviors do appear, they are often learned patterns passed down across generations.
So, instead of asking whether Gen Z is less intelligent, perhaps the more important question is this: Did Gen Z create the system they are now being judged by and should intelligence be measured solely through standardized tests and IQ scores?
Rather than assigning blame, the focus should be on preparing young people to think deeply, critically and independently in a world deliberately designed to distract them.
