Neuroscientist study reveals that Gen Z has become the first generation to be less intelligent than its predecessor, the Millennials. For the first time in 100 years, young people are scoring lower than their parents on IQ tests and core skills like memory, reading, and focus. This is happening mainly in the US and Europe. The main cause appears to be excessive screen time and digital device use, particularly in schools and social settings. While some suggest Gen Z is just developing different skills, research shows actual declines in fundamental problem-solving abilities.
