We conclude that there cannot be a strongly cohesive network of communicating, unifying intelligences through the whole universe if (1) such galactic civilizations evolve upward from individual planetary societies and if (2) the velocity of light is indeed a fixed limit on the speed of information transmission, as…
Past experiments have shown persuasively that exercise spurs the birth of new mitochondria in muscle cells and improves the vigor of the existing organelles. This upsurge in mitochondria, in turn, has been linked not only to improvements in exercise endurance but to increased longevity in animals and reduced risk for…
On the successful completion of a test, they should not have said,“I’m so proud of you. You’re so smart. They should have said, “I’m so proud of you. You must have really studied hard”. This appeals to controllable effort rather than to unchangeable talent. It’s called “growth mindset” praise. More than 30 years of…
IQ is malleable. IQ has been shown to vary over one’s life span, and it is surprisingly vulnerable to environmental influences. It can change if one is stressed, old, or living in a different culture from the testing majority. A child’s IQ is influenced by his or her family, too. Growing up in the same household tends…
Thousands of experiments confirm that babies learn about their environment through a series of increasingly self-corrected ideas. They experience sensory observations, make predictions about what they observe, design and deploy experiments capable of testing their predictions, evaluate their tests, and add that…

The brain’s chief job description—yours, mine, and your hopelessly adorable children’s—is to help our bodies survive another day. The reason for survival is as old as Darwin and as young as sexting: so we can project our genes into the next generation. Will a human willingly overcome self-interest to ensure the…
One of the more startling findings about early enrichment is the effect of music. You can hardly pick up a newspaper without seeing some kind of reference to how Mozart makes people smarter. The governor of Georgia recently proposed spending $105,000 of state money to provide every newborn baby with a compact disc of…
;ct. What parents want even influences the very ways they label children. Sara Harkness and Charles Super found that when parents in three cultures were asked about intelligence, their views of what constitutes a smart child differed.^^ In America, an "intelligent" child is one who is aggressive and competitive; in…
Ann Druyan and I come from families that knew grinding poverty. But our parents were passionate readers. One of our grandmothers learned to read because her father, a subsistence farmer, traded a sack of onions to an itinerant teacher. She read for the next hundred years. Our parents had personal hygiene and the germ…
I prefer sociobiologist E. O. Wilson's view of us as unfortunate tribal carnivores that have acquired intelligence. Our evolution is more like that of social insects; the advances in knowledge and understanding that we prize are more a property of the human nests we call civilization than of its individual members…
