The Great Dimming The Modern IQ Decline What if humanity isn't getting smarter—but slowly losing its ability to think? Around the world, researchers are reporting an unsettling trend: after decades of rising intelligence scores, IQ levels are now declining in many developed nations. Attention spans are shrinking. Critical thinking is fading. Memory is weakening. Is it simply a change in education and technology...or is something far more profound happening? In The Great Dimming, bestselling author Kevin B. DiBacco explores the science behind one of the most overlooked crises of our time. From ultra-processed foods, microplastics, environmental toxins, chronic stress, and poor sleep to social media addiction, digital overload, and sedentary lifestyles, this eye-opening investigation uncovers the hidden forces that may be reshaping the human brain. Drawing on current research and practical solutions, DiBacco separates fact from fear, revealing what the evidence tells us—and, more importantly, what each of us can do to protect our cognitive health. If our greatest resource is our ability to think, the question isn't whether the Great Dimming is real... It's whether we're willing to stop it before it's too late.
