Is Intelligence Determined by Age 11?

In this episode, we discuss a groundbreaking study from the University of Edinburgh, published in *Genomic Psychiatry*, which analyzed cognitive development over 25 years. The research reveals that nearly half of late-life intelligence can be traced back to cognitive abilities at age 11, suggesting intelligence might be largely set by this age. Additionally, higher childhood intelligence is linked to longer life expectancy, indicating the importance of early cognitive development. We explore what this means for nurturing young minds and why diverse experiences—such as travel, sports, and creative activities—are crucial for lifelong brain health.
